How to Draft and Review Commercial Contracts in Ontario

Introduction

A well-drafted commercial contract is one of the most valuable assets a business can have. It clearly defines the rights and obligations of each party, allocates risk, and provides a roadmap for resolving disputes if the relationship breaks down. Conversely, a poorly drafted contract—or worse, a handshake deal with no written agreement at all—can expose your business to significant financial and legal risk.

This article is a practical guide to drafting and reviewing commercial contracts in Ontario. We cover the essential elements of a valid contract, walk through the key clauses found in most commercial agreements, highlight common drafting pitfalls, and discuss industry-specific considerations. Whether you are preparing a services agreement, a supply contract, a licensing deal, or an employment arrangement, the principles discussed here will help you negotiate and document your business relationships more effectively.

Essential Elements of a Valid Contract

Before diving into specific clauses, it is important to understand the legal requirements for a binding contract in Ontario. If any of these elements is missing, the agreement may be unenforceable.

Offer and Acceptance

A contract begins with an offer—a clear, definite proposal by one party to another. The offer must be sufficiently certain in its terms to be capable of acceptance. An invitation to treat (such as a price list or advertisement) is generally not an offer. Acceptance must be unconditional and communicated to the offeror. If the offeree changes any term of the offer, that constitutes a counter-offer, which destroys the original offer and creates a new offer that the original offeror can accept or reject.

Consideration

Consideration is the price each party pays for the other’s promise. It can be money, goods, services, a promise to do something, or a promise to refrain from doing something. Consideration must be real but need not be adequate—courts will not generally inquire into whether the parties made a good bargain. Past consideration (a benefit conferred before the promise was made) is generally not valid consideration. A promise to perform an existing legal obligation is also not good consideration, unless additional consideration is provided.

Capacity and Legality

Both parties must have the legal capacity to enter into the contract. This means they must be of the age of majority (18 in Ontario), of sound mind, and not under the influence of substances that impair judgment to the extent that they cannot understand the nature and consequences of the agreement. A corporation has the capacity of a natural person under s. 15 of the OBCA. A contract whose subject matter is illegal or contrary to public policy is void and unenforceable.

Certainty of Terms

The terms of a contract must be sufficiently certain that a court can determine what the parties agreed to and enforce the agreement. An agreement to agree—where essential terms are left to be negotiated later—is generally not enforceable. Courts have some latitude to imply reasonable terms to fill gaps, but they will not write a contract for the parties.

Key Clauses in Commercial Contracts

Every well-drafted commercial contract contains a set of core clauses that define the parties’ relationship, allocate risk, and provide mechanisms for resolving disputes. The following sections discuss the most important clauses and their functions.

Representations and Warranties

Representations are statements of fact made by one party to induce the other to enter the contract. Warranties are contractual promises about the truth or accuracy of certain facts. Together, they serve as risk allocation tools: the party making the representation or warranty bears the risk that the statement is false. If a representation turns out to be false, the innocent party may have the right to rescind the contract or claim damages. If a warranty is breached, the typical remedy is damages.

In drafting representations and warranties, be specific and accurate. Avoid making representations you cannot verify. Use knowledge qualifiers ("to the best of the Seller’s knowledge") where appropriate, but be aware that such qualifiers are often heavily negotiated.

Indemnification

Indemnification clauses require one party to compensate the other for specified losses. They are the primary mechanism for allocating risk in commercial contracts. A well-drafted indemnification clause specifies the trigger events, the scope of losses covered (including whether third-party claims are included), any caps or baskets, the procedure for making and defending claims, and the survival period after the contract ends.

Indemnification obligations should be carefully matched to the parties’ respective risk profiles. The party best positioned to control a risk should generally bear it. Caps on indemnification exposure should reflect the value of the transaction and the nature of the risks involved.

Limitation of Liability

Limitation of liability clauses cap the total amount a party can recover from the other, typically expressed as a dollar amount or as a multiple of fees paid. These clauses commonly exclude indirect, consequential, incidental, and punitive damages. Ontario courts generally enforce such clauses between sophisticated commercial parties, provided they are not unconscionable.

It is important to consider the interaction between your limitation of liability clause and your indemnification obligations. A poorly drafted contract may create a situation where the indemnification obligation exceeds the liability cap, creating ambiguity about the intended risk allocation.

Termination

Termination clauses specify the circumstances under which the contract can be ended. Common termination triggers include material breach that remains uncured after a notice period, insolvency or bankruptcy of a party, and termination for convenience on a specified notice period. The clause should address what happens upon termination—payment of outstanding amounts, return of confidential information, wind-down of services—and which provisions survive termination.

Force Majeure

A force majeure clause excuses a party from performing its obligations when performance is prevented or hindered by extraordinary events beyond the party’s control, such as natural disasters, pandemics, war, government orders, or labour strikes. In Ontario, there is no implied force majeure doctrine—if your contract does not contain a force majeure clause, you may be held to your obligations regardless of external events, unless the common law doctrine of frustration applies.

Draft force majeure clauses carefully. Specify the qualifying events with reasonable particularity, define the consequences (suspension of obligations, right to terminate), and include a notice requirement and a long-stop date beyond which either party may terminate.

Dispute Resolution

Dispute resolution clauses establish how disagreements will be handled. Common approaches include mandatory mediation as a first step, followed by arbitration or litigation if mediation fails. Arbitration clauses should specify the arbitral institution (if any), the number of arbitrators, the seat of arbitration, and the language of proceedings. The Arbitration Act, 1991, S.O. 1991, c. 17, provides the statutory framework for domestic arbitration in Ontario.

Governing Law and Jurisdiction

A governing law clause specifies which jurisdiction’s laws govern the interpretation and enforcement of the contract. A jurisdiction clause (or forum selection clause) specifies where disputes will be heard. For Ontario businesses, it is typically advisable to select Ontario law and Ontario courts as the governing law and exclusive forum. If your counterparty is in another jurisdiction, the choice of law and forum can be a significant negotiation point.

Entire Agreement, Severability, and Assignment

The entire agreement clause (also called a merger or integration clause) states that the written contract constitutes the entire agreement between the parties and supersedes all prior negotiations, representations, and understandings. This clause is important because it limits the ability of a party to introduce extrinsic evidence of oral promises or side agreements.

A severability clause provides that if any provision of the contract is found to be invalid or unenforceable, the remaining provisions continue in effect. Without a severability clause, the invalidity of one provision could potentially render the entire contract unenforceable.

An assignment clause addresses whether and how a party may transfer its rights and obligations under the contract to a third party. Most commercial contracts restrict assignment without the other party’s prior written consent.

Common Drafting Pitfalls

Even experienced business owners make mistakes when drafting or reviewing contracts. The following are among the most common pitfalls we see.

Ambiguity

Ambiguous language is the single biggest source of contract disputes. If a clause can reasonably be interpreted in two different ways, you can be sure that each party will adopt the interpretation most favourable to itself. Use plain, precise language. Define key terms. Avoid jargon and legalistic phrasing that obscures meaning rather than clarifying it.

Boilerplate Neglect

Many business owners focus on the commercial terms—price, scope, timeline—and treat the "boilerplate" provisions (entire agreement, severability, governing law, assignment, notices) as an afterthought. This is a mistake. Boilerplate clauses have real legal consequences. A missing or poorly drafted entire agreement clause can allow a party to introduce extrinsic evidence of oral promises. A missing governing law clause can result in an expensive jurisdictional dispute.

Electronic Contracts and the Electronic Commerce Act, 2000

Many commercial contracts are now executed electronically—via email, electronic signatures, or click-through agreements. The Electronic Commerce Act, 2000, S.O. 2000, c. 17 (the "ECA") provides that information shall not be denied legal effect solely because it is in electronic form. An electronic signature satisfies a legal requirement for a signature, provided the other party consents to accepting an electronic signature.

However, the ECA contains important exceptions. Certain documents—including wills, powers of attorney, and certain real property instruments—cannot be created or signed electronically under the ECA. If your business regularly enters into contracts electronically, ensure your processes comply with the ECA and that you maintain adequate records of electronic communications and signatures.

Industry-Specific Considerations

While the core principles of contract drafting apply across industries, certain types of agreements require special attention.

Services Agreements

Services agreements should clearly define the scope of services, deliverables, timelines, acceptance criteria, and payment terms. Ambiguity about scope is the most common source of disputes in services engagements. Include a change order process for scope modifications and address intellectual property ownership for any work product created during the engagement.

Supply and Distribution Agreements

Supply agreements require careful attention to pricing mechanisms (fixed price, cost-plus, volume-based), delivery terms, quality specifications, inspection and rejection procedures, and risk of loss during transit. Distribution agreements should address exclusivity, territory, minimum purchase commitments, and the circumstances under which the manufacturer may appoint additional distributors.

Licensing Agreements

Licensing agreements grant one party the right to use another party’s intellectual property—a trademark, patent, copyright, or trade secret. Key terms include the scope of the licence (exclusive vs. non-exclusive, field of use, territory), royalty or fee structure, quality control requirements, sublicensing rights, and termination provisions. Ensure that the licence grant is clearly defined and does not inadvertently grant broader rights than intended.

Employment Agreements and the Employment Standards Act, 2000

Employment agreements in Ontario must comply with the Employment Standards Act, 2000, S.O. 2000, c. 41 (the "ESA"). The ESA establishes minimum standards for wages, hours of work, overtime, vacation, public holidays, termination notice, and severance pay. Any provision in an employment contract that provides less than the ESA minimum is void and unenforceable. Ontario courts have struck down entire termination clauses where even one provision falls below ESA minimums, as in Waksdale v. Swegon North America Inc., 2020 ONCA 391.

Employment agreements should also address restrictive covenants (non-competition, non-solicitation, and confidentiality), intellectual property assignment, and probationary periods. Non-competition clauses in employment agreements are presumptively unenforceable in Ontario and will only be upheld if the employer can demonstrate that a non-solicitation clause would be insufficient to protect its legitimate interests.

Frequently Asked Questions

Q: Is a verbal contract enforceable in Ontario?

A: Yes, in most cases. Ontario law does not require contracts to be in writing to be enforceable, with certain exceptions under the Statute of Frauds, R.S.O. 1990, c. S.19 (which requires certain contracts—such as contracts for the sale of land and guarantees—to be evidenced in writing). However, verbal contracts are extremely difficult to prove. We always recommend putting your agreements in writing.

Q: Can I use a contract template I found online?

A: Online templates can be a useful starting point, but they should never be used without careful review and customization by a qualified lawyer. Templates are generic by nature and may not reflect Ontario law, your specific industry, or the particular risks of your transaction. A template that works for one transaction may be wholly inadequate for another.

Q: What happens if my contract does not have a force majeure clause?

A: In Ontario, there is no implied force majeure doctrine. Without a force majeure clause, you would need to rely on the common law doctrine of frustration, which has a very high threshold: the supervening event must fundamentally alter the nature of the contractual obligations, not merely make performance more expensive or difficult. The doctrine of frustration was considered by the Supreme Court of Canada in Naylor Group Inc. v. Ellis-Don Construction Ltd., 2001 SCC 58.

Q: Are electronic signatures legally valid in Ontario?

A: Yes, in most cases. The Electronic Commerce Act, 2000 provides that an electronic signature satisfies a legal requirement for a signature, as long as the other party consents to the use of electronic signatures. However, certain categories of documents are excluded from the ECA, including wills, powers of attorney, and certain real property instruments.

Q: What should I do if the other party wants to use their standard form contract?

A: Never sign a counterparty’s standard form contract without having it reviewed by your own lawyer. Standard form contracts are drafted to favour the party that prepared them. Booni Law can identify provisions that are unfavourable to you and negotiate amendments to achieve a fairer allocation of risk.
