Contract Law in Canada: Formation, Interpretation, Performance, Breach, and Remedies in Common Law and Quebec Civil Law

Contract Law in Canada: Formation, Interpretation, Performance, Breach, and Remedies in Common Law and Quebec Civil Law

Introduction

Contract law is one of the principal foundations of private law in Canada. It governs the creation and enforcement of legally binding agreements between individuals, businesses, public bodies, and other legal entities. Commercial transactions, employment relationships, property arrangements, consumer purchases, professional services, loans, construction projects, and countless other everyday activities depend upon contractual obligations.

Although Canada has a unified federal constitutional structure, it does not have one uniform system of contract law. The country’s legal tradition is bijural: the common law governs contracts in the provinces and territories outside Quebec, while Quebec’s private law is principally governed by the Civil Code of Québec. This distinction affects how agreements are formed, how contractual language is interpreted, what obligations arise from good faith, how contractual breach is established, and which remedies may be available.

The distinction should not be exaggerated. Canadian common law and Quebec civil law address many of the same practical questions: whether the parties reached an agreement, whether they intended legal consequences, what their obligations mean, whether they performed them, and what follows when one party fails to comply. Both systems recognise the importance of consent, contractual certainty, good faith, and the protection of legitimate legal expectations. They nevertheless approach these questions through different legal sources and doctrinal structures.

In common-law jurisdictions, contract law has developed through judicial precedent, supplemented by legislation governing particular areas such as consumer transactions, electronic commerce, employment, sale of goods, and secured transactions. In Quebec, the Civil Code provides a systematic statutory framework for obligations arising from contracts and other legal sources. Judicial decisions remain important in interpreting and applying the Code, but the Code itself occupies the central position in private law.

Contract law in Canada must also be understood in its statutory and constitutional setting. Federal legislation may govern contracts within areas of federal jurisdiction, while provincial and territorial legislatures regulate much of the law affecting ordinary private transactions. The applicable rules may therefore depend not only on whether a dispute arises in Quebec or a common-law province, but also on the subject matter of the agreement and the relevant legislation.

This article examines the principal elements of Canadian contract law: the formation and validity of agreements, contractual interpretation, performance and good faith, breach and discharge, and the remedies available when contractual obligations are not fulfilled. It compares the common-law and Quebec civil-law approaches while identifying the practical implications of the country’s bijural system.

1. The Legal Foundations of Contract Law in Canada

1.1 A bijural system of private law

The Canadian legal system combines common law and civil law traditions. The distinction is especially important in private law, which governs legal relationships between private persons and organisations.

In the provinces and territories outside Quebec, contract law is primarily based on common-law principles developed by courts over time. Judicial decisions establish and refine doctrines concerning offer and acceptance, consideration, intention to create legal relations, contractual interpretation, implied terms, breach, and remedies.

In Quebec, contractual obligations are governed principally by the Civil Code of Québec (CCQ). Book Five, entitled Obligations, contains the principal rules governing contracts, civil liability, and other sources of obligations. The Code addresses the formation, interpretation, effects, performance, and extinction of obligations in a structured statutory framework.

The distinction does not mean that Quebec operates outside the Canadian legal system. Quebec courts apply federal legislation within federal jurisdiction, and the Supreme Court of Canada provides a common final appellate authority. Federal legislation may also interact with provincial private law. The result is a legal system in which two private-law traditions operate within one constitutional state.

1.2 Constitutional allocation of legislative authority

The Constitution Act, 1867 distributes legislative authority between Parliament and the provincial legislatures.

Section 92(13) assigns provinces authority over property and civil rights within the province. This provision is a central constitutional foundation for provincial private law, including ordinary contractual relationships.

Section 91 gives Parliament authority over specified federal subjects. Federal legislation may consequently affect contracts in areas such as banking, navigation and shipping, bankruptcy and insolvency, intellectual property, interprovincial trade, and other matters within federal competence.

The constitutional allocation does not mean that every contract connected with a federally regulated subject is governed exclusively by federal law. The legal analysis depends on the relevant constitutional head of power, the subject matter of the agreement, the applicable legislation, and the relationship between federal and provincial law.

For example, a banking agreement may be subject to federal banking legislation while also raising questions of provincial contract law. Similarly, a contract involving intellectual property may be affected by federal statutes while relying on provincial rules to determine certain private-law obligations.

1.3 Sources of contract law

The sources of Canadian contract law vary according to the jurisdiction and the subject matter.

In common-law provinces and territories, important sources include:

• Judicial precedent;
• Provincial and territorial statutes;
• Federal legislation within Parliament’s constitutional authority;
• The common law governing contractual obligations; and
• Equitable principles affecting particular contractual relationships and remedies.

In Quebec, the principal sources include:

• The Civil Code of Québec;
• Other provincial legislation;
• Applicable federal legislation;
• Judicial interpretation of the Civil Code and statutes; and
• General principles of civil law.

The Civil Code does not operate as an isolated or exhaustive statement of every rule relevant to a transaction. Other legislation may establish mandatory requirements, regulate particular industries, or create additional rights and obligations.

1.4 The importance of statutory regulation

Contractual freedom is not unlimited in either legal tradition. Legislatures may regulate particular transactions to protect consumers, employees, tenants, borrowers, investors, and other groups.

Examples include:

• Provincial consumer protection legislation;
• Sale of goods legislation;
• Employment standards legislation;
• Residential tenancy legislation;
• Insurance legislation;
• Electronic commerce legislation;
• Federal banking and financial legislation; and
• Legislation governing intellectual property and insolvency.

Some statutory rules are mandatory and cannot be excluded by agreement. Others apply unless the parties make a legally effective alternative arrangement.

A contract may therefore be valid under general contract principles but contain a term that is unenforceable because it conflicts with mandatory legislation.

2. The Concept of a Contract and the Intention to Create Legal Relations

A contract is a legally enforceable agreement that creates obligations recognised by law.

Not every agreement is a contract. People make arrangements in social, family, professional, and commercial settings without necessarily intending to assume legally enforceable obligations.

The law must therefore distinguish between a genuine contractual commitment and an informal understanding.

2.1 Common-law approach

In common-law jurisdictions, the traditional analysis of contract formation generally considers:

1. Agreement, usually demonstrated through offer and acceptance;
2. Consideration, subject to recognised exceptions and doctrines;
3. Intention to create legal relations; and
4. Sufficient certainty of the essential terms.

The elements are not always applied as a rigid checklist. Courts examine the parties’ words, conduct, circumstances, and the nature of the transaction.

An agreement may be expressed in writing, orally, or through conduct. The absence of a formal signed document does not automatically prevent a contract from arising.

2.2 Quebec civil-law approach

Quebec law does not use the common-law doctrine of consideration as a general requirement for contractual formation.

Article 1378 CCQ defines a contract as an agreement of wills by which one or several persons obligate themselves to one or several other persons to perform a prestation.

Under article 1385, a contract is formed by the sole exchange of consent between persons having capacity to contract, unless the law also requires a particular form as a condition of formation, or the parties make the formation of the contract subject to a solemn form.

The Code therefore focuses on consent, capacity, and the legally required form of the agreement.

A contract may be formed through an exchange of consent even where no consideration in the common-law sense is provided. However, special rules may apply to particular contracts, including formal requirements for certain transactions.

2.3 Intention and the nature of the transaction

The intention to create legal relations remains important in identifying whether the parties intended their agreement to have legal consequences.

In commercial settings, courts commonly infer an intention to create legal relations from the objective circumstances. In social or domestic arrangements, the question may require closer examination.

The legal analysis is objective. It generally concerns what a reasonable person would understand from the parties’ words and conduct in context, rather than a party’s undisclosed private intention.

In Quebec, the question is approached through the requirements of consent and the general rules governing contractual formation and interpretation. The Civil Code’s structure does not simply reproduce the common-law doctrine of intention to create legal relations.

3. Formation of Contracts in Common-Law Canada

3.1 Offer and acceptance

The traditional common-law model of contract formation begins with an offer made by one party and accepted by another.

An offer is a sufficiently definite expression of willingness to enter into a contract on stated terms, made in circumstances indicating that the offeror intends to be bound if the other party accepts. It must be distinguished from an invitation to treat: a preliminary communication inviting another person to make an offer or begin negotiations.

Advertisements, catalogues, price lists, and displays of goods are often invitations to treat rather than binding offers. However, the legal character of a communication depends on its wording and context. An advertisement may constitute an offer where its language demonstrates a clear intention to be bound upon fulfilment of specified conditions.

Acceptance must correspond to the offer. A response that introduces materially different terms will ordinarily constitute a counter-offer rather than acceptance. A counter-offer generally terminates the original offer unless the parties’ conduct or subsequent communications indicate otherwise.

Acceptance may be communicated expressly, orally or in writing, or inferred from conduct. For example, a customer who orders goods on stated terms and a supplier who accepts and dispatches them may demonstrate agreement through their actions.

The central question is whether the parties objectively manifested agreement on sufficiently certain terms.

3.2 Communication of acceptance

The time and place at which a contract is formed can be important, particularly where the parties communicate remotely or operate in different provinces or countries.

At common law, the general rule for instantaneous communications is that acceptance becomes effective when received by the offeror, subject to the terms of the offer and the circumstances of communication.

The postal acceptance rule is a historical exception under which acceptance may become effective when a properly addressed and stamped acceptance letter is posted, rather than when it is received. Its application is limited and depends on the nature of the transaction and the parties’ intentions. It does not ordinarily govern modern instantaneous electronic communications.

Electronic commerce legislation in Canadian jurisdictions supports the legal recognition of electronic communications and provides rules concerning the time and place of sending and receiving electronic records. The precise rules depend on the applicable statute.

3.3 Consideration

Consideration is a central requirement of ordinary contract formation in common-law jurisdictions.

It refers to something of legal value exchanged between the parties. It may consist of a promise, an act, a forbearance, or another legally recognised benefit or detriment.

For example, where a supplier promises to deliver equipment and a purchaser promises to pay a specified price, each promise forms part of the exchange supporting the contract.

Consideration need not be economically equivalent to the value received. Courts do not generally determine whether the bargain was financially fair merely by comparing the value of the parties’ promises. The question is whether legally sufficient consideration exists, not whether the transaction was commercially advantageous.

Past consideration is generally insufficient because an act performed before a promise is made is not ordinarily given in exchange for that later promise. However, the law recognises limited circumstances in which an earlier request and an understood expectation of payment may support a subsequent promise.

The doctrine also raises questions where parties agree to vary an existing contract. A promise to perform an obligation already owed to the same party may not ordinarily constitute fresh consideration at common law. The application of this principle has, however, been refined by judicial decisions, including cases concerning practical benefits and contractual variations.

3.4 Promises without consideration

The common law distinguishes between a contract supported by consideration and certain promises that may be enforceable through other doctrines.

A gratuitous promise, meaning a promise made without an exchange, is generally not enforceable as an ordinary contract merely because the promisor expressed an intention to fulfil it.

Equity may nevertheless provide protection in particular circumstances through doctrines such as promissory estoppel. Broadly, promissory estoppel may prevent a party from insisting on strict legal rights where that party has made a clear representation or promise, the other party has relied on it, and it would be inequitable to permit the promisor to depart from it.

The doctrine has historically operated principally as a defence rather than as an independent cause of action, although its precise operation depends on the circumstances and the relevant jurisdiction.

3.5 Comparison with Quebec

Quebec civil law does not require consideration as a general condition of contractual formation.

Under article 1385 CCQ, a contract is formed through the exchange of consent between persons with capacity, unless the law or the parties require a particular form. The contract must also have a cause and an object.

The absence of a common-law consideration requirement does not mean that every promise is automatically enforceable. The agreement must still satisfy the requirements of civil law, including genuine consent, capacity, lawful cause and object, and any applicable formal requirements.

This is one of the most important differences between the two systems. A transaction that raises a consideration problem in a common-law province may be analysed differently in Quebec, where the inquiry focuses on the Code’s conditions for contractual validity.

4. Capacity, Consent, and the Validity of Agreements

4.1 Capacity to contract

A person must have the legal capacity required to enter into a valid contract.

Capacity issues may arise where a party is a minor, an adult subject to protective legal measures, a person who lacks the relevant mental capacity, or a corporation or other legal entity acting beyond its legal authority.

In common-law jurisdictions, the rules governing minors’ contracts distinguish between different categories of agreements. Contracts for necessaries and certain beneficial arrangements may receive different treatment from other transactions. The applicable rules also depend on provincial legislation.

In Quebec, capacity is addressed through the Civil Code of Québec. Articles 1398 and following concern consent, while the Code’s provisions concerning persons and capacity establish the broader legal framework. Minors and persons subject to protective supervision may enter into certain acts, but the legal consequences depend on the nature of the transaction and the applicable statutory provisions.

Corporate capacity is also relevant. A company ordinarily enters into contracts through individuals acting with actual or apparent authority, subject to the governing corporate statute and the circumstances of the transaction.

4.2 Genuine consent

A valid agreement requires genuine consent. A party’s apparent agreement may be legally defective where it was obtained through a recognised form of coercion, deception, or mistake.

Common-law doctrines include:

• Misrepresentation;
• Duress;
• Undue influence;
• Mistake; and
• Unconscionability.

Quebec civil law addresses defects of consent through the Civil Code, particularly articles 1399–1408.

Article 1399 provides that consent must be free and enlightened. It may be vitiated by error, fear, or lesion in the circumstances recognised by the Code.

4.3 Misrepresentation

Misrepresentation occurs where a false statement of fact induces another party to enter into a contract.

In common-law jurisdictions, the legal consequences depend on the nature of the statement, the state of mind of the person making it, whether it induced the agreement, and the remedy sought.

Misrepresentation may be fraudulent, negligent, or innocent. Fraudulent misrepresentation involves deliberate or reckless dishonesty. Negligent misrepresentation may arise where a person makes a statement carelessly in circumstances giving rise to a duty of care. Innocent misrepresentation involves a false statement made without the relevant fault.

Depending on the circumstances, remedies may include rescission, damages, or both where legally available.

In Quebec, error and fraud are addressed within the Code’s framework for defects of consent. Article 1400 concerns error, while article 1401 addresses error induced by fraud, including a lie or the concealment of a material fact. The legal consequences are assessed under the civil-law rules governing nullity and restitution.

4.4 Duress and fear

Duress involves pressure that unlawfully or illegitimately deprives a party of meaningful freedom of choice.

In common-law contract law, economic duress may arise where illegitimate pressure is applied, the pressure contributes to the party’s decision to contract or vary an agreement, and the circumstances justify relief.

The mere fact that a party faces commercial pressure or makes an unfavourable bargain does not establish duress. The court examines the nature of the pressure, available alternatives, protest or affirmation, and the overall circumstances.

In Quebec, article 1402 CCQ addresses fear induced by violence or threats, including circumstances in which the fear concerns serious injury to the person or property of a party or another person. The Code also recognises certain forms of exploitation and fear involving a third person.

4.5 Undue influence and unconscionability

Undue influence concerns the improper use of a relationship of trust, dependence, or influence to obtain another person’s agreement.

Unconscionability is concerned with transactions involving serious inequality of bargaining power and an improvident bargain. It may be particularly relevant where a vulnerable party enters a standard-form agreement or accepts terms that substantially disadvantage that party.

The Supreme Court of Canada considered unconscionability in Uber Technologies Inc. v. Heller, 2020 SCC 16. The case concerned an arbitration clause imposing substantial practical barriers on a driver seeking to pursue a claim. The Court held the clause unconscionable in the circumstances.

The decision is important beyond arbitration. It illustrates that contractual freedom does not necessarily justify enforcement of an arrangement produced by significant bargaining inequality and an improvident result.

Quebec civil law approaches related concerns through its rules on defects of consent, lesion in legally recognised circumstances, good faith, and public order. Article 1406 CCQ addresses lesion, while article 1437 deals with abusive clauses in consumer and adhesion contracts.

4.6 Illegality and public order

A contract must not require conduct prohibited by law or violate applicable public order requirements.

In common-law jurisdictions, an illegal contract may be unenforceable, although the consequences depend on the relevant legislation, the nature of the illegality, and the public policy considerations involved.

In Quebec, the validity of a contract is affected by the requirements concerning lawful cause and object and the rules of public order. Articles 1410 and 1411 CCQ address the object and cause of contracts, while other provisions govern nullity and its consequences.

A contractual term may also be invalid even where the remainder of the agreement can continue to operate. Whether the entire agreement or only a particular provision is affected depends on the governing legal rules and the structure of the transaction.

5. Contractual Terms and the Structure of Agreements

5.1 Express terms

Express terms are obligations and conditions stated by the parties, whether in a written agreement or through an oral agreement.

They may address:

• The identity of the parties;
• The subject matter;
• Price and payment;
• Delivery and performance;
• Duration and renewal;
• Warranties;
• Confidentiality;
• Allocation of risk;
• Termination;
• Dispute resolution; and
• Remedies for non-performance.

Written contracts provide evidence of the parties’ agreement and can reduce uncertainty. Nevertheless, the written document must be interpreted in accordance with the applicable legal principles. A signed document is not necessarily the complete or legally decisive expression of every aspect of the parties’ relationship.

5.2 Implied terms

Not every contractual obligation must be expressly written into the agreement.

In common-law jurisdictions, terms may be implied by law, by fact, or through established custom and usage, subject to the relevant legal tests.

A term implied in fact is generally intended to give effect to the parties’ objectively understood agreement. Courts are cautious about implying terms merely because they appear reasonable or desirable after a dispute arises.

Terms implied by law may attach to particular categories of contractual relationships, such as employment, tenancy, or insurance. Legislation may also imply terms into contracts, particularly in the sale of goods and consumer transactions.

In Quebec, article 1434 CCQ provides that a contract validly formed binds the parties not only as to what is expressed in it but also as to what follows from its nature and from usage, equity, or law.

This provision reflects the Code’s systematic approach to the effects of contracts. The parties’ obligations are not necessarily confined to the literal words of the agreement.

5.3 Conditions, warranties, and intermediate terms

Common-law contract law traditionally distinguishes between conditions and warranties, although modern analysis also recognises intermediate or innominate terms.

A condition is generally a term whose breach may entitle the innocent party to terminate the contract and claim damages. A warranty is ordinarily a lesser obligation whose breach gives rise to damages but does not automatically justify termination.

The classification depends on the contract, the statutory framework, and the nature and consequences of the breach.

An intermediate term is one where the consequences of breach determine whether termination is justified. The question is whether the breach deprives the innocent party of substantially the whole benefit intended under the contract.

This approach avoids treating every breach of an important-looking term as automatically giving a right to terminate.

Quebec civil law does not simply reproduce the common-law taxonomy. The consequences of non-performance are analysed under the Code’s rules governing obligations, resolution, resiliation, and damages.

5.4 Exclusion and limitation clauses

Commercial agreements frequently include clauses limiting or excluding liability.

An exclusion clause may attempt to remove responsibility for specified categories of loss, while a limitation clause may cap damages or restrict the remedies available.

Courts generally seek to give effect to contractual language where it is valid and sufficiently clear. However, statutory protections, public policy, unconscionability, and rules of interpretation may restrict enforcement.

In Tercon Contractors Ltd. v. British Columbia (Transportation and Highways), 2010 SCC 4, the Supreme Court established a structured approach to exclusion clauses in common-law contract disputes.

The analysis generally asks:

1. Whether the clause, properly interpreted, applies to the circumstances;
2. Whether the clause was unconscionable at the time the contract was made; and
3. Whether an overriding public policy reason nevertheless justifies refusing enforcement.

The case remains important in understanding the relationship between contractual freedom and judicial control of exclusion clauses.

Quebec’s approach must be considered separately, particularly in light of the Civil Code’s rules concerning public order, consumer contracts, adhesion contracts, and abusive clauses.

6. Interpretation of Contracts

6.1 The objective approach to interpretation

Contractual interpretation seeks to determine the meaning of the agreement and the obligations the parties objectively undertook.

In common-law jurisdictions, courts generally interpret a contract by considering the words used, the agreement as a whole, and the circumstances in which it was made. The objective is to identify the meaning that a reasonable person, possessing the relevant background knowledge available to the parties at the time of formation, would attribute to the contractual language.

The court does not simply ask what one party privately intended. Nor does it ordinarily rewrite the agreement to produce what appears, after the dispute has arisen, to be a fairer bargain.

The Supreme Court of Canada explained the modern approach in Sattva Capital Corp. v. Creston Moly Corp., 2014 SCC 53. Contractual interpretation is generally a question of mixed fact and law because it involves applying legal principles to the words of the contract in the context of the surrounding circumstances.

6.2 The text and the factual matrix

The factual matrix consists of the background circumstances known or reasonably available to both parties at the time the contract was made. It may include the commercial setting, the purpose of the agreement, the nature of the transaction, and relevant circumstances surrounding its formation.

The factual matrix assists in understanding the language used. It cannot ordinarily be employed to overwhelm, contradict, or replace the actual contractual wording.

This distinction protects contractual certainty. If a court could disregard the written language whenever one party later presented a more attractive interpretation of the background circumstances, written agreements would lose much of their commercial value.

The approach in Sattva therefore requires courts to read the words in context while remaining anchored in the text.

6.3 Entire agreement and surrounding documents

A contract may consist of more than one document. A main agreement may incorporate schedules, technical specifications, policies, statements of work, amendments, or other documents.

The court must determine which documents form part of the agreement and how they interact.

An entire agreement clause may state that the written document represents the complete agreement between the parties and supersedes earlier negotiations or representations. Such a clause can be important, but it does not automatically resolve every dispute about interpretation, misrepresentation, statutory rights, or the validity of contractual terms.

Similarly, a merger clause cannot necessarily exclude mandatory statutory protections or defeat a claim that the agreement itself was induced by legally actionable misconduct.

6.4 Ambiguity and interpretation against the drafter

Where contractual language remains genuinely ambiguous after the ordinary interpretive process, courts may apply the doctrine of contra proferentem. Under this principle, ambiguity may be resolved against the party who drafted or relies on the disputed wording, particularly where that party seeks to exclude or limit liability.

The doctrine is not a substitute for careful interpretation. Courts first attempt to determine the meaning of the agreement as a whole, in context.

In consumer and insurance contracts, the principle may be particularly significant where one party prepared standard wording and the other had little or no opportunity to negotiate it.

6.5 Standard-form contracts

Standard-form contracts are widely used in modern commerce. They include insurance policies, banking agreements, software licences, telecommunications contracts, online service terms, and consumer agreements.

They are generally drafted in advance by one party and presented to the other on a take-it-or-leave-it basis.

The Supreme Court considered their interpretation in Ledcor Construction Ltd. v. Northbridge Indemnity Insurance Co., 2016 SCC 37. The Court recognised that standard-form contracts raise distinctive interpretive issues because the factual matrix may be less individualised than in a negotiated agreement.

The interpretation of standard-form wording can have precedential significance beyond the immediate parties. Courts may therefore give particular attention to the wording, commercial purpose, and reasonable expectations associated with the standard form.

6.6 Quebec’s approach to interpretation

Quebec’s Civil Code provides a statutory framework for contractual interpretation.

Articles 1425–1432 CCQ establish the principal interpretive rules.

Article 1425 directs the interpreter to seek the common intention of the parties rather than stop at the literal meaning of the words.

Article 1426 requires consideration of the nature of the contract, the circumstances in which it was formed, the interpretation already given to it by the parties, and usage.

Article 1427 provides that each clause must be interpreted in light of the others, giving each the meaning that results from the contract as a whole.

Article 1428 favours an interpretation that gives a clause some effect rather than one that renders it meaningless.

Article 1432 provides that, in case of doubt, a contract is interpreted in favour of the person who contracted the obligation and against the person who stipulated it. In consumer or adhesion contracts, it is interpreted in favour of the consumer or adhering party.

The civil-law approach is therefore not simply a search for literal meaning. It seeks to identify the parties’ common intention through the Code’s interpretive principles.

7. Good Faith in Canadian Contract Law

Good faith is one of the most significant areas of modern Canadian contract law. It is also an area in which the common-law and civil-law systems have developed important similarities alongside doctrinal differences.

7.1 Good faith under Quebec civil law

Good faith occupies a central position in Quebec’s contractual framework.

Article 6 CCQ requires persons to exercise their civil rights in good faith. Article 7 prohibits exercising a right with the intention of injuring another or in an excessive and unreasonable manner contrary to the requirements of good faith.

Article 1375 provides that the parties must conduct themselves in good faith at the time an obligation arises, while it is performed, and when it is extinguished.

These provisions establish good faith as a general requirement throughout the life of contractual obligations.

It is not merely a rule applicable to exceptional circumstances. It informs the exercise of contractual rights, the conduct of negotiations, performance, and the termination of obligations.

7.2 Good faith in common-law jurisdictions

Historically, common-law contract law recognised good faith obligations in particular contexts but resisted a broad, general doctrine applying to every contract.

The Supreme Court’s decision in Bhasin v. Hrynew, 2014 SCC 71, significantly developed this area.

The Court recognised good faith as an organising principle of common-law contract law and established a general duty of honest contractual performance.

The duty requires parties not to lie or knowingly mislead one another about matters directly linked to the performance of their contractual obligations.

It applies regardless of whether the parties expressly included an honesty clause in their agreement.

However, the duty is not equivalent to a general obligation to disclose all relevant information, act altruistically, or subordinate one’s commercial interests to those of the other party.

A contracting party may generally pursue its own legitimate economic interests, provided it does not perform its contractual obligations dishonestly.

7.3 Honest performance and the limits of the duty

The duty of honest performance is concerned with dishonesty in the performance of contractual obligations.

A party may breach the duty by knowingly misleading its contractual partner about an intention or action relevant to performance. The duty does not create a general fiduciary relationship between ordinary contracting parties.

In C.M. Callow Inc. v. Zollinger, 2020 SCC 45, the Supreme Court considered the duty of honest performance in the context of a contract termination provision. The case clarified that a party may breach the duty not only through an express false statement but also through conduct that knowingly misleads the other party in relation to contractual performance.

The Court emphasised that the duty must be applied in its contractual context. It does not impose a general obligation to disclose every intention or development, but it prohibits knowingly misleading conduct.

7.4 Good faith in the exercise of contractual discretion

Some contracts grant one party discretion to make decisions affecting the other party. Examples include decisions about allocation, pricing mechanisms, approvals, performance standards, or the exercise of contractual options.

The exercise of such discretion may be subject to a duty of good faith.

In Wastech Services Ltd. v. Greater Vancouver Sewerage and Drainage District, 2021 SCC 7, the Supreme Court considered the good-faith exercise of contractual discretion.

The Court explained that a discretionary power must be exercised consistently with the purpose for which the contract granted it. The analysis is not whether the decision was commercially disadvantageous to the other party, but whether the discretion was exercised in a manner consistent with the contractual purpose and the legitimate expectations arising from the agreement.

This does not mean that a party must always exercise discretion in the other party’s favour. It means that contractual discretion cannot be used for a purpose inconsistent with the bargain.

7.5 Good faith is not fiduciary loyalty

A distinction must be maintained between good faith and fiduciary duties.

An ordinary contracting party does not generally owe a duty to place the other party’s interests first. Nor does the duty of honest performance ordinarily require full disclosure of every matter that might influence the other party’s decisions.

Fiduciary duties arise in particular relationships characterised by legally recognised obligations of loyalty, such as certain relationships involving trustees, agents, directors, and other persons entrusted with discretionary power over another’s interests.

Good faith is broader in its application but generally less demanding in its content. It requires compliance with the minimum standards of honest and appropriate contractual conduct, not self-sacrifice.

7.6 Comparing the two systems

The common-law and Quebec approaches both recognise that contractual rights must not be exercised abusively or dishonestly.

However, their doctrinal foundations differ.

In Quebec, good faith is expressly established in the Civil Code and applies throughout the life of obligations under articles 6, 7, and 1375.

In common-law jurisdictions, Bhasin recognised an organising principle of good faith and a specific duty of honest performance, while Callow and Wastech developed its application in particular contexts.

It would therefore be inaccurate to say that the two systems are identical. The underlying concern is shared, but the legal structure and the way courts formulate the relevant duties remain distinct.

8. Performance of Contractual Obligations

8.1 The duty to perform

Once a valid contract has been formed, the parties are generally required to perform the obligations they have undertaken.

Performance may involve payment, delivery of goods, provision of services, transfer of property, completion of work, granting of access, or compliance with specified standards.

The contract may establish a particular timetable, sequence of performance, quality requirement, or method of delivery. The parties must comply with those obligations unless the agreement or the law permits variation, suspension, or termination.

A party cannot ordinarily avoid performance simply because the bargain has become less profitable or less convenient.

8.2 Time and place of performance

The contract may specify when and where an obligation must be performed.

Where no express term exists, the applicable law and the nature of the obligation may determine the appropriate time and place.

In some contracts, time is essential. A delay may defeat the commercial purpose of the agreement, particularly where goods are required for a particular event or a construction project must meet a fixed deadline.

In other cases, a delay may be compensable without justifying termination.

The consequences depend on the contract, the applicable statutory rules, and the seriousness of the non-performance.

8.3 Substantial performance

Common-law jurisdictions recognise that a party may, in some circumstances, be entitled to payment despite failing to perform every minor detail of the contract.

The doctrine of substantial performance may apply where the essential obligations have been fulfilled and the remaining deficiencies are relatively minor.

The innocent party may nevertheless be entitled to damages or a deduction reflecting the cost of correcting the defects.

The doctrine is not a general permission to perform contracts incompletely. Its application depends on the seriousness of the defects, the purpose of the agreement, and the overall circumstances.

Quebec civil law addresses incomplete performance through the Code’s rules on obligations, creditor remedies, and the consequences of non-performance.

8.4 Cooperation between contracting parties

Some contractual obligations cannot be performed effectively without cooperation.

A customer may have to provide access to premises, supply specifications, approve plans, or deliver information. A contractor may be unable to complete the work without those actions.

The parties must therefore consider obligations that arise expressly or implicitly from the nature of the contract.

In Quebec, article 1375’s good-faith requirement is relevant to the manner in which parties cooperate in performing obligations.

In common-law jurisdictions, cooperation may be required through express terms, implied terms, the duty of honest performance, or other established doctrines.

8.5 Contractual variations

Parties may agree to change their contractual obligations.

A variation may concern price, delivery, scope of work, deadlines, specifications, or the duration of the agreement.

The variation must satisfy the applicable requirements for contractual formation and validity.

In common-law jurisdictions, consideration may be relevant to whether a variation is enforceable, although statutory provisions and judicial developments may alter the analysis in particular contexts.

In Quebec, the parties may generally modify their contractual obligations by mutual consent, subject to applicable formal requirements, mandatory rules, and the Code’s provisions governing obligations.

A party should not assume that a unilateral change is effective merely because it has been communicated to the other side.

9. Discharge and Termination of Contracts

A contract may come to an end through performance, agreement, operation of law, or the exercise of a legally recognised termination right.

9.1 Performance and discharge

The ordinary way of discharging contractual obligations is through proper performance.

Where both parties fulfil their obligations, the contractual relationship may be completed without further liability, subject to continuing obligations such as warranties, confidentiality, indemnities, or post-termination duties.

9.2 Agreement to terminate

Parties may mutually agree to terminate or replace an existing contract.

The agreement may provide for payment, return of property, release of claims, continuing confidentiality obligations, or other arrangements.

The legal effect depends on the terms of the termination agreement and the applicable rules governing its formation and validity.

9.3 Termination for breach

A serious breach may entitle the innocent party to terminate the contract, provided the relevant legal requirements are satisfied.

In common-law jurisdictions, the right to terminate may arise where a condition is breached, an intermediate term is breached with sufficiently serious consequences, or the contract expressly provides a termination right.

A party should distinguish between termination and damages. A breach may justify compensation without giving the innocent party a right to end the contract.

9.4 Resiliation and resolution in Quebec

Quebec civil law uses its own terminology and framework for ending contracts because of non-performance.

The Civil Code distinguishes between different forms of termination, including resolution and resiliation.

Resolution generally operates in relation to contracts involving obligations that have not been performed, with consequences that may include retroactive unwinding and restitution. Resiliation is commonly associated with ending a contract of successive performance, generally for the future.

The distinction is important in contracts such as leases, services, and continuing commercial arrangements.

The applicable rules are found in the Civil Code’s provisions concerning the effects and remedies of obligations, including articles 1590 and following.

9.5 Frustration and impossibility

A contract may become impossible to perform because of an unforeseen event occurring after formation.

In common-law jurisdictions, the doctrine of frustration may discharge a contract where an event, without the fault of either party, makes performance radically different from what was undertaken.

Mere increased expense, inconvenience, or reduced profitability is not generally enough.

The doctrine is applied narrowly because commercial parties are expected to allocate foreseeable risks through their agreements.

In Quebec, the analysis is conducted through the Code’s provisions concerning impossibility of performance and superior force (force majeure), particularly articles 1470 and 1693.

The legal consequences depend on whether the event meets the statutory definition and whether the debtor is legally excused from performance.

10. Breach of Contract

10.1 Meaning of breach

A breach of contract occurs when a party fails to perform a contractual obligation in the manner required by the agreement and the applicable law.

It may involve:

• Failure to pay an agreed price;
• Late delivery of goods;
• Failure to provide contracted services;
• Delivery of defective or non-conforming goods;
• Failure to complete construction work;
• Refusal to perform an agreed obligation;
• Violation of confidentiality or exclusivity provisions; or
• Failure to comply with an agreed termination or renewal procedure.

The seriousness of the breach determines the available remedies. Some breaches give rise to damages only, while others may justify termination, specific performance, or other relief.

10.2 Actual and anticipatory breach

An actual breach occurs when a party fails to perform an obligation when performance is due.

An anticipatory breach arises where, before performance is due, a party clearly indicates that it will not perform a contractual obligation or acts in a manner demonstrating that it cannot or will not fulfil the agreement.

In common-law jurisdictions, a sufficiently clear repudiation may allow the innocent party to accept the repudiation, terminate the contract, and claim damages without waiting until the original performance date.

However, the innocent party must decide whether to accept the repudiation or affirm the contract. An unjustified termination may itself constitute a breach.

Quebec civil law addresses refusal and failure to perform through the Code’s rules governing obligations, default, and the remedies available to creditors. The analysis is not simply a transplantation of common-law anticipatory repudiation terminology.

10.3 Materiality and seriousness

Not every breach justifies termination.

A minor defect in performance may entitle the innocent party to compensation or correction but not to abandon the entire agreement.

The court considers the contractual language, the nature of the obligation, the consequences of the breach, and whether the innocent party has lost substantially the benefit for which it contracted.

For example, a small delay in delivering office furniture may be compensable without justifying termination. A failure to deliver essential equipment by a deadline that makes the equipment useless for its intended purpose may be fundamentally different.

10.4 Repudiation and election

Where a serious breach gives rise to a right to terminate, the innocent party must generally communicate or otherwise clearly demonstrate its decision to accept the breach as terminating the contract.

The innocent party may instead affirm the agreement and insist on continued performance, where legally possible.

This choice is sometimes described as an election between termination and affirmation.

The decision may have important consequences for damages, continuing obligations, and the rights of both parties. A party that continues to perform without clarifying its position may create uncertainty about whether it has accepted the breach or affirmed the contract.

10.5 Breach of good faith

A party may also breach a contractual obligation by acting dishonestly in the performance of the agreement, even where it appears to comply with the literal wording of a particular clause.

Under common law, the duty of honest performance established in Bhasin v. Hrynew may give rise to liability where a party knowingly misleads its contractual partner about matters connected with performance.

In Quebec, failure to comply with the good-faith requirements of articles 6, 7, and 1375 CCQ may have consequences under the Civil Code’s framework for contractual obligations and liability.

The precise remedy depends on the nature of the conduct and the loss suffered.

11. Remedies for Breach of Contract in Common-Law Jurisdictions

The principal purpose of contractual remedies is generally to protect the innocent party’s legally recognised contractual interests.

The most familiar remedy is damages. However, common-law courts may also grant equitable relief, including specific performance and injunctions, where the legal requirements are satisfied.

11.1 Expectation damages

Expectation damages are designed to place the innocent party, so far as money can do so, in the position it would have occupied if the contract had been properly performed.

Suppose a supplier agrees to deliver specialised equipment for $50,000 but fails to deliver it. The buyer must obtain equivalent equipment elsewhere for $65,000.

Subject to the applicable rules on causation, mitigation, and remoteness, the buyer may be entitled to recover the additional $15,000 needed to obtain substitute performance.

Expectation damages are not automatically equal to the amount claimed by the innocent party. The claimant must establish the loss caused by the breach and demonstrate that it is legally recoverable.

11.2 Reliance damages

Reliance damages compensate a party for expenditure incurred in reliance on the contract.

They may be relevant where the claimant cannot establish the expected profit with sufficient certainty but can demonstrate that it incurred expenses because it reasonably relied on the agreement.

For example, a business may incur preparatory costs, hire personnel, purchase materials, or reserve facilities in anticipation of contractual performance.

Reliance damages seek to restore the claimant to the position it would have occupied had it not relied on the agreement, subject to the applicable rules and any limits on recovery.

11.3 Restitutionary relief

Restitution is concerned with reversing unjustified enrichment or restoring benefits transferred under circumstances recognised by law.

It is distinct from ordinary expectation damages.

For example, where a contract is rescinded or otherwise unwound, a party may be required to return money, property, or another benefit received.

The precise availability of restitution depends on the basis of the claim, the legal consequences of termination or rescission, and whether the law permits recovery independently of contractual damages.

11.4 Nominal damages

Nominal damages may be awarded where a legal right has been breached but the claimant has not established substantial compensable loss.

The award recognises that a legal wrong occurred even though the claimant cannot demonstrate a significant financial consequence.

Nominal damages should be distinguished from compensation for actual economic loss.

11.5 Liquidated damages and penalty clauses

Contracts sometimes specify in advance the amount payable if a particular obligation is breached.

A properly drafted liquidated damages clause may provide a genuine contractual estimate or allocation of the loss likely to arise from breach. It can reduce uncertainty and avoid the need for detailed proof of damages in later proceedings.

However, a clause designed to punish a party rather than protect a legitimate contractual interest may be treated as an unenforceable penalty under common-law principles.

The distinction depends on the clause’s substance, purpose, and the applicable legal test.

In H.F. Clarke Ltd. v. Thermidaire Corp. Ltd., [1976] 1 SCR 319, the Supreme Court considered the distinction between damages and penalties in the context of contractual obligations. The broader common-law approach requires examination of the function and legal effect of the clause, rather than accepting its label as conclusive.

11.6 Specific performance

Specific performance is an equitable remedy requiring a party to perform the contractual obligation itself.

It is not automatically available whenever a breach occurs.

Historically, courts have been more willing to order specific performance where the subject matter is unique or damages would be inadequate. Land is a traditional example, although the remedy is not automatic in every land transaction.

Specific performance may also be considered in relation to unique goods or particular contractual obligations where monetary compensation would not adequately protect the claimant.

The court considers whether the remedy is appropriate, whether the claimant has acted equitably, and whether the order can be framed and supervised effectively.

11.7 Injunctions

An injunction is a court order requiring a person to do something or refrain from doing something.

In contract disputes, injunctions may be used to restrain conduct contrary to a contractual obligation, such as misuse of confidential information or breach of an enforceable restrictive covenant.

An interlocutory injunction may be sought before the final determination of the dispute to preserve the position of the parties.

The Supreme Court’s decision in RJR—MacDonald Inc. v. Canada (Attorney General), [1994] 1 SCR 311, established the familiar three-part test for interlocutory injunctions:

1. There must be a serious question to be tried;
2. The applicant must demonstrate that it would suffer irreparable harm if relief were refused; and
3. The balance of convenience must favour granting the injunction.

The test applies within the relevant procedural context and is not a guarantee that an injunction will be granted whenever a contract is alleged to have been breached.

11.8 Mitigation of loss

A claimant seeking damages must generally take reasonable steps to limit the loss caused by the breach.

This is known as the duty to mitigate.

For example, if a supplier fails to deliver goods, the buyer may be expected to seek a reasonable substitute rather than allow avoidable losses to accumulate.

Mitigation does not require the claimant to take unreasonable risks, incur disproportionate expenses, or accept an unsuitable alternative.

The question is whether the claimant acted reasonably in the circumstances.

11.9 Remoteness and causation

Not every loss that follows a breach is legally recoverable.

The claimant must establish a sufficient causal connection between the breach and the claimed loss. The loss must also satisfy the applicable rules on remoteness.

The traditional common-law approach is associated with Hadley v. Baxendale (1854), which distinguishes losses arising naturally from the breach from losses that were within the parties’ reasonable contemplation because of particular circumstances communicated at the time of contracting.

Canadian courts apply the principles of causation, foreseeability, and contractual risk allocation in determining recoverable damages.

A claimant cannot ordinarily recover every consequential financial disadvantage merely because it occurred after the breach.

12. Contractual Remedies under Quebec Civil Law

Quebec’s Civil Code establishes a systematic framework for remedies arising from non-performance.

12.1 The creditor’s remedies

Article 1590 CCQ provides that a creditor is entitled to demand that the obligation be performed in full, properly, and without delay.

Where the debtor fails to perform, the creditor may, subject to the Code’s requirements, seek:

• Specific performance;
• Resolution or resiliation of the contract;
• A reduction of the creditor’s own obligation;
• Damages; or
• Other appropriate relief provided by law.

The creditor’s rights are therefore framed through the Code’s general law of obligations rather than solely through a common-law classification of damages and equitable remedies.

12.2 Default and formal notice

The Civil Code contains rules governing default, including the circumstances in which a debtor is considered to be in default.

Articles 1594 and following address default and the methods by which it may be established.

Depending on the nature of the obligation and the circumstances, a creditor may need to place the debtor in default by formal notice. In other situations, default may arise automatically under the Code or the agreement.

Formal notice can be important because it may establish the point from which particular consequences of non-performance arise, including liability for delay.

12.3 Specific performance

Quebec civil law recognises the creditor’s right to demand performance of the obligation itself, subject to the nature of the obligation and the applicable legal limits.

Article 1601 CCQ provides for specific performance, while article 1602 addresses circumstances in which the creditor may be authorised to perform the obligation or have it performed at the debtor’s expense.

The remedy must be considered in the context of the nature of the obligation. A court cannot always compel personal services or conduct where performance is legally or practically inappropriate.

12.4 Resolution and resiliation

Where contractual non-performance is sufficiently serious, the creditor may seek resolution or resiliation, subject to the relevant requirements.

Resolution generally unwinds a contract and may require restitution of prestations already performed. Resiliation ordinarily ends a contract of successive performance for the future.

The distinction matters because the consequences of ending a one-time sale are not necessarily the same as ending a continuing service agreement or lease.

The Civil Code contains specific rules governing these consequences and the restitution of prestations.

12.5 Reduction of the creditor’s obligation

In appropriate circumstances, the creditor may seek a reduction of its own obligation where the debtor has failed to perform properly.

For example, where services have been supplied but are materially deficient, the creditor may have a legal basis to seek a corresponding reduction in the amount payable, subject to the applicable rules.

This remedy reflects the reciprocal nature of many contractual obligations.

12.6 Damages under article 1607

Article 1607 CCQ provides that a creditor is entitled to damages for bodily, moral, or material injury that is an immediate and direct consequence of the debtor’s default.

The provision establishes the connection between non-performance and compensable injury.

Article 1611 addresses the scope of damages, including loss sustained and profit of which the creditor has been deprived.

Article 1613 provides an important limitation in contractual matters: where non-performance does not result from intentional or gross fault, the debtor is liable only for damages that were foreseen or foreseeable at the time the obligation was contracted, and those damages must remain an immediate and direct consequence of the non-performance.

These provisions demonstrate the Code’s structured approach to causation, foreseeability, and compensation.

12.7 Contractual liability and article 1458

Article 1458 CCQ is central to contractual civil liability.

It requires every person to honour their contractual undertakings. A person who fails to do so is liable for bodily, moral, or material injury caused to the other contracting party and must make reparation.

The provision also prevents a contracting party from avoiding the rules of contractual liability by choosing the rules governing extracontractual liability where the injury results from failure to honour contractual obligations.

This distinction between contractual and extracontractual liability is an important feature of Quebec civil law.

13. The Common-Law and Quebec Civil-Law Approaches Compared

The two systems address similar practical problems but organise the law differently.

Issue	Common-law provinces and territories	Quebec
Main legal source	Judicial precedent and legislation	Civil Code of Québec and legislation
Contract formation	Offer, acceptance, consideration, intention, certainty	Consent, capacity, cause, object, and required form
Consideration	Generally required for ordinary simple contracts	Not a general condition of formation
Consent defects	Misrepresentation, duress, undue influence, mistake, unconscionability	Error, fear, fraud, lesion in recognised circumstances
Implied obligations	Terms implied by law, fact, custom, or statute	Article 1434 and other Code provisions
Good faith	Organising principle and specific doctrines, including honest performance	General requirements under arts. 6, 7 and 1375
Interpretation	Objective meaning, text, factual matrix, contract as a whole	Common intention, arts. 1425–1432
Breach	Failure to perform contractual obligations	Failure to honour obligations under the Code
Termination	Termination or discharge under common law and statute	Resolution, resiliation, and other Code remedies
Damages	Expectation, reliance, restitutionary and other recognised remedies	Civil liability and damages under arts. 1458, 1607 and following
Specific performance	Equitable remedy, subject to judicial discretion	Remedy under the Code, subject to applicable requirements

The comparison reveals both convergence and difference.

Both systems seek to enforce valid agreements, protect legitimate expectations, and provide compensation for legally recognised losses. Both also recognise that contractual freedom operates within limits imposed by legislation, public order, good faith, and principles protecting vulnerable parties.

However, the legal route to a result may differ. A lawyer or researcher cannot safely assume that a doctrine developed in a common-law province applies in the same form in Quebec.

14. Consumer Contracts and Standard-Form Agreements

14.1 Consumer protection as a limit on contractual freedom

Consumer contracts are an important area in which general contract principles interact with protective legislation.

Consumers commonly enter agreements drafted by businesses, including online purchases, telecommunications services, financial products, insurance policies, and subscription arrangements.

The consumer may have little opportunity to negotiate the wording. Legislatures therefore impose statutory obligations on businesses and provide remedies that may not be available under ordinary contract law alone.

Consumer protection legislation is principally provincial, although federal legislation may regulate particular products, services, and industries.

14.2 Quebec consumer contracts

Quebec’s Consumer Protection Act operates alongside the Civil Code.

The Act imposes mandatory requirements concerning representations, disclosure, cancellation rights, warranties, and prohibited contractual practices in specified consumer transactions.

The Civil Code also provides protections for consumer and adhesion contracts. Article 1437 CCQ allows an abusive clause in a consumer or adhesion contract to be declared null or the obligation arising from it to be reduced.

This is an important statutory control over unfair contractual terms.

14.3 Ontario and other provincial consumer legislation

Ontario’s Consumer Protection Act, 2002 regulates a range of consumer transactions and provides protections concerning unfair practices, disclosure, cancellation, and other matters.

Other provinces have their own consumer protection legislation. The precise protections differ, and the applicable statute depends on the transaction and the relevant jurisdiction.

A contract that is enforceable under general common-law principles may nevertheless contain provisions that are prohibited or restricted by consumer legislation.

14.4 Online contracts and electronic acceptance

Electronic contracts are now central to Canadian commerce.

A person may accept contractual terms by clicking a button, creating an account, purchasing a service, or continuing to use a digital platform after receiving appropriate notice.

The enforceability of online terms depends on whether the user received reasonable notice and objectively manifested agreement, as well as on the applicable legislation and other contract principles.

In Rudder v. Microsoft Corp. (1999), 2 CPR (4th) 474 (Ont. SCJ), the Ontario Superior Court considered the enforceability of online contractual terms in a digital service arrangement.

The broader lesson is that electronic form does not automatically prevent contract formation. The critical issues concern notice, assent, clarity, and applicable legal requirements.

14.5 Unfair and unconscionable standard terms

Standard-form agreements can create significant bargaining imbalances.

Courts may scrutinise clauses that attempt to exclude essential remedies, impose disproportionate obligations, or prevent access to an effective dispute-resolution mechanism.

Uber Technologies Inc. v. Heller, 2020 SCC 16, remains a particularly important illustration of the limits of contractual enforcement where the practical effect of an arbitration clause is to make a legal remedy inaccessible.

The decision should not be understood as invalidating standard-form agreements generally. It confirms that their enforceability remains subject to applicable doctrines and statutory protections.

15. Commercial Contracts and Risk Allocation

Commercial agreements are often designed not merely to create obligations but to allocate risks between parties.

A carefully drafted commercial contract may specify who bears the risk of delay, defective performance, price changes, changes in law, supply interruptions, currency fluctuations, and unforeseen events.

15.1 Warranties and representations

Warranties are contractual promises concerning the quality, condition, performance, or characteristics of goods or services.

Representations are statements that may induce a party to enter into a contract. Depending on their nature and legal effect, inaccurate representations may give rise to contractual or non-contractual liability.

The distinction is important because a statement may be a term of the contract, a representation, or both.

15.2 Indemnity clauses

An indemnity clause allocates responsibility for specified losses, claims, liabilities, or expenses.

For example, a contractor may agree to indemnify a property owner for certain losses arising from the contractor’s negligence or breach of specified obligations.

The scope of an indemnity depends on its wording and the applicable interpretive rules. Courts do not necessarily read an indemnity as covering every loss connected with the contractual relationship.

15.3 Force majeure clauses

A force majeure clause allocates the consequences of specified extraordinary events that affect performance.

The clause may identify events such as natural disasters, war, government restrictions, or supply interruptions and establish whether performance is suspended, extended, or terminated.

The existence of a force majeure event does not automatically excuse performance. The party relying on the clause must establish that the event falls within its wording and that the required causal and procedural conditions have been satisfied.

In Quebec, the Code’s rules on superior force may also be relevant, particularly article 1470 and the provisions governing impossibility of performance.

15.4 Entire agreement, governing law, and jurisdiction clauses

Commercial contracts commonly include provisions identifying the complete agreement, governing law, and forum for disputes.

A governing law clause selects the law intended to govern the contract, subject to mandatory legal rules and applicable conflict-of-laws principles.

A jurisdiction clause identifies the court or courts in which disputes may be brought. It should be distinguished from an arbitration clause, which directs disputes to private adjudication.

In cross-border contracts, these provisions can be decisive. A Canadian business contracting with a foreign supplier may need to consider whether the agreement selects provincial law, foreign law, or a particular dispute-resolution mechanism.

Canadian courts assess such clauses under the relevant conflict-of-laws principles and applicable statutory rules. A choice-of-law clause does not necessarily displace mandatory protections or public policy.

16. Limitation Periods and Contractual Claims

A party who wishes to sue for breach of contract must consider the applicable limitation period.

Limitation periods are principally governed by provincial and territorial legislation, although federal statutes may establish particular periods in matters within federal jurisdiction.

Ontario’s Limitations Act, 2002, for example, generally establishes a two-year basic limitation period running from discovery of the claim, subject to the statute’s provisions and exceptions.

Other provinces have their own limitation regimes. Quebec addresses prescription through Book Eight of the Civil Code of Québec, including the general three-year prescription period for personal actions under article 2925, subject to specific rules and exceptions.

The date on which a claim is discovered, the nature of the cause of action, statutory suspension or extension provisions, and contractual terms may all be relevant.

A contractual claim should therefore not be assessed by assuming that one limitation period applies throughout Canada.

17. Practical Example: A Commercial Supply Agreement

Assume that a Canadian company enters into an agreement with a manufacturer for the supply of specialised machinery.

The agreement specifies a price, delivery date, technical specifications, installation requirements, and a warranty period.

The manufacturer accepts the order and receives an advance payment. However, it delivers machinery that does not meet the agreed specifications and refuses to correct the defects.

The buyer may have several legal questions to consider.

First, was a valid contract formed? In a common-law province, the analysis would examine offer, acceptance, consideration, intention, and certainty. In Quebec, it would focus on consent, capacity, cause, object, and any required form.

Second, what were the manufacturer’s contractual obligations? The court would interpret the agreement, technical specifications, incorporated documents, and relevant statutory terms.

Third, was the machinery defective in a way that constituted breach? The answer may depend on express warranties, implied obligations, sale of goods legislation, and the technical evidence.

Fourth, did the manufacturer act in good faith? If it knowingly misrepresented the machinery’s compliance or deliberately misled the buyer about its ability to correct the defects, additional contractual duties may be relevant.

Fifth, what remedies are available? The buyer may seek damages, repair or replacement, termination, restitution, or specific performance, depending on the applicable legal system and the nature of the breach.

Finally, the buyer must consider mitigation. It may need to obtain substitute machinery, take reasonable steps to limit operational losses, and preserve evidence of the costs caused by the breach.

If the agreement contains an exclusion clause, limitation of liability, or dispute-resolution provision, those terms must also be examined. Their enforceability will depend on the wording, applicable law, statutory protections, and relevant judicial doctrines.

The example demonstrates why contract disputes require more than identifying a broken promise. The legal analysis must connect formation, interpretation, performance, breach, causation, and remedies.

18. Key Takeaways

1. Canadian contract law is bijural. Common-law principles govern private contracts in the provinces and territories outside Quebec, while Quebec’s private law is principally governed by the Civil Code of Québec.

2. Section 92(13) of the Constitution Act, 1867 gives provinces legislative authority over property and civil rights, providing the constitutional foundation for much of Canadian private law.

3. In common-law jurisdictions, contract formation traditionally requires offer, acceptance, consideration, intention to create legal relations, and sufficiently certain terms.

4. Quebec civil law does not generally require consideration. Article 1385 CCQ focuses on consent, capacity, cause, object, and any legally required form.

5. Contractual consent must be genuine. Misrepresentation, fraud, duress, undue influence, mistake, and other recognised defects may affect enforceability.

6. Contractual terms may be express, implied by law, implied from the circumstances, or incorporated through legislation and established usage.

7. Contractual interpretation requires consideration of the agreement as a whole. Common-law courts apply the principles developed in Sattva, while Quebec courts apply articles 1425–1432 CCQ.

8. Good faith is central to modern Canadian contract law. In common-law jurisdictions, Bhasin v. Hrynew established an organising principle of good faith and a general duty of honest performance.

9. In Quebec, articles 6, 7, and 1375 CCQ expressly require the exercise of civil rights and the performance of obligations in good faith.

10. A breach of contract occurs when a party fails to fulfil a contractual obligation. The seriousness of the breach determines whether damages, termination, or other relief may be available.

11. Common-law remedies include expectation damages, reliance damages, restitutionary relief, specific performance, and injunctions.

12. Quebec’s Civil Code provides a structured range of remedies, including specific performance, resolution, resiliation, reduction of the creditor’s obligation, and damages.

13. Damages are subject to rules concerning causation, foreseeability, remoteness, and mitigation.

14. Consumer protection legislation and other mandatory statutes may restrict contractual freedom and invalidate or limit particular terms.

15. Electronic agreements can create legally binding contracts, but notice, acceptance, clarity, and statutory compliance remain important.

16. Limitation periods differ across provinces and territories. Quebec’s general prescription period for personal actions is three years, subject to exceptions, while other jurisdictions apply their own statutory rules.

17. A contract must be analysed under the law applicable to the transaction. A doctrine or remedy familiar in one province should not automatically be assumed to operate identically in another.

19. Frequently Asked Questions

1. What is contract law in Canada?

Contract law governs legally enforceable agreements and the obligations created by them. It determines how contracts are formed, interpreted, performed, terminated, and enforced.

2. Does Canada have one national contract law?

No. Most private contract law falls within provincial jurisdiction. Common-law principles govern most provinces and territories, while Quebec applies its civil-law system under the Civil Code of Québec. Federal legislation also regulates particular contractual subjects within federal jurisdiction.

3. What is the difference between common-law contract law and Quebec contract law?

Common-law contract law relies substantially on judicial precedent and generally requires consideration for an ordinary simple contract. Quebec relies on the Civil Code and does not generally require consideration. Its formation rules focus on consent, capacity, cause, object, and required form.

4. What are the essential elements of a contract under Canadian common law?

The traditional requirements are offer, acceptance, consideration, intention to create legal relations, and sufficient certainty of terms. The precise analysis depends on the nature of the agreement and applicable legislation.

5. Is consideration required in Quebec?

No. Consideration is not a general condition of contractual formation under Quebec civil law. Article 1385 CCQ provides that a contract is generally formed through an exchange of consent between persons with capacity, subject to other legal requirements.

6. Can an oral agreement be legally binding in Canada?

Yes. Oral contracts may be enforceable if the applicable formation requirements are satisfied. However, certain transactions are subject to statutory writing, signature, registration, or other formal requirements. Proving the terms of an oral agreement may also be more difficult.

7. Are electronic contracts legally valid in Canada?

Generally, yes. Electronic commerce legislation recognises electronic records and signatures in many circumstances. The enforceability of a particular online agreement depends on the applicable law, the method of acceptance, notice of the terms, and any statutory formalities.

8. What happens if a person signs a contract without understanding its terms?

The consequences depend on the circumstances. A party is not automatically released merely because they did not read an agreement. However, misrepresentation, fraud, duress, unconscionability, lack of capacity, and statutory consumer protections may affect enforceability.

9. What is an implied term?

An implied term is an obligation that applies even though it is not expressly written into the contract. In common-law jurisdictions, terms may be implied by law, fact, custom, or statute. In Quebec, article 1434 CCQ recognises obligations arising from the nature of the contract, usage, equity, and law.

10. What does good faith mean in Canadian contract law?

Good faith requires contractual parties to comply with recognised standards of honest and proper conduct. Its exact legal expression differs between common-law jurisdictions and Quebec. It does not generally require an ordinary contracting party to put the other party’s interests first.

11. What did the Supreme Court decide in Bhasin v. Hrynew?

In Bhasin v. Hrynew, 2014 SCC 71, the Supreme Court recognised good faith as an organising principle of common-law contract law and established a general duty of honest contractual performance.

12. Can a party terminate a contract because of a breach?

Sometimes. A serious breach, breach of a condition, or exercise of a valid contractual termination right may justify termination. A minor breach will not necessarily permit the innocent party to end the agreement.

13. What is anticipatory breach?

Anticipatory breach occurs where a party clearly indicates before performance is due that it will not fulfil its contractual obligations. In common-law jurisdictions, the innocent party may be able to accept the repudiation and claim damages without waiting for the performance date.

14. What is the difference between resolution and resiliation in Quebec?

Resolution generally involves unwinding a contract, potentially with restitution of prestations already performed. Resiliation generally ends a contract of successive performance for the future. The distinction is important for continuing agreements such as service contracts and leases.

15. What damages can be claimed for breach of contract?

Depending on the applicable law, a claimant may recover financial losses, lost profits, reasonable reliance expenditure, and other legally recognised losses caused by the breach. The claimant must establish causation and satisfy the relevant rules on foreseeability, remoteness, and mitigation.

16. What are expectation damages?

Expectation damages aim to place the innocent party in the financial position it would have occupied if the contract had been properly performed.

17. What is the duty to mitigate?

The duty to mitigate requires a claimant to take reasonable steps to limit losses caused by a contractual breach. A claimant generally cannot recover losses that could reasonably have been avoided.

18. Can a Canadian court order a party to perform a contract instead of paying damages?

Yes. Specific performance may be available where the legal requirements are met and monetary damages would not provide an adequate remedy. Its availability differs between common-law and Quebec civil-law systems.

19. Are exclusion clauses enforceable in Canada?

They may be, depending on their wording, the circumstances of formation, applicable legislation, and public policy. The Supreme Court’s decision in Tercon Contractors Ltd. v. British Columbia, 2010 SCC 4, provides an important common-law framework for assessing exclusion clauses.

20. What is an unconscionable contract?

An unconscionable agreement involves circumstances that justify judicial intervention because of serious bargaining inequality and an improvident bargain. The precise legal test depends on the applicable legal system. Uber Technologies Inc. v. Heller, 2020 SCC 16, is a leading Canadian example.

21. What is the limitation period for breach of contract in Canada?

There is no single national limitation period. Ontario generally applies a two-year basic limitation period under its Limitations Act, 2002, subject to statutory rules and exceptions. Quebec generally applies a three-year prescription period to personal actions under article 2925 CCQ, also subject to exceptions.

22. Can a contract be valid but contain an unenforceable clause?

Yes. A particular term may be invalid or unenforceable because it violates mandatory legislation, public order, consumer protection rules, or other legal requirements. The remainder of the agreement may continue to operate if the law permits.

23. What law applies to a contract between parties in different Canadian provinces?

The answer depends on the contract’s governing law clause, the applicable conflict-of-laws rules, the nature of the dispute, and mandatory legislation. The parties may choose a governing law in many commercial circumstances, but their choice is not unlimited.

24. Are contracts with government bodies governed by ordinary contract law?

Government contracts may be subject to ordinary contractual principles, but they can also involve public-law requirements, statutory powers, procurement rules, constitutional considerations, and special remedies. The legal analysis depends on the nature of the government body’s authority and the transaction.

25. Why is the distinction between common law and Quebec civil law important for international businesses?

A business operating in Canada must understand that contractual formation, interpretation, good faith, remedies, and prescription may differ between Quebec and the other provinces and territories. Contracts intended for use throughout Canada should be drafted with these differences in mind.

Conclusion

Contract law provides the legal architecture through which individuals and organisations organise their economic and personal relationships. It establishes when promises become enforceable, how contractual obligations are interpreted, what standards govern performance, and which remedies are available when an agreement is not honoured.

The Canadian system is particularly interesting because it combines two major private-law traditions. Common-law contract law has developed through judicial precedent and statutory intervention, while Quebec civil law provides a codified framework in which consent, obligations, good faith, and contractual remedies are organised through the Civil Code of Québec.

The differences are substantial. Consideration, the formation of agreements, the role of good faith, contractual interpretation, and the structure of remedies cannot be approached as though the two systems were interchangeable. At the same time, both traditions seek to protect legitimate contractual expectations and to ensure that private autonomy operates within a coherent legal framework.

Modern Canadian contract law also demonstrates that contractual freedom is not absolute. Consumer protection legislation, rules against unconscionability, good-faith obligations, public policy, and mandatory statutory requirements place limits on the enforcement of agreements. These limits are particularly important in contemporary commercial relationships, where standard-form contracts, digital transactions, and unequal bargaining power can significantly affect the practical ability of parties to negotiate and enforce their rights.

For businesses, lawyers, students, and individuals dealing with Canadian transactions, the central lesson is that a contract must be understood within its legal environment. Its wording matters, but so do the circumstances of formation, the applicable provincial or federal legislation, the nature of the parties’ obligations, and the legal consequences of non-performance. Understanding these elements is essential to understanding how Canadian private law protects agreements and regulates the relationships built upon them.
