Misrepresentation in contract law in Ontario is a false statement of fact made by one contracting party to another that induces the other to enter the contract. Ontario courts recognize three types of misrepresentation, fraudulent, negligent, and innocent misrepresentation, and the available remedies, such as rescission or damages, depend on which category applies.
For business owners, purchasers, and sellers, this area of law comes up constantly. A seller overstates the revenue of a business being sold. A supplier misdescribes the condition of equipment. A franchisor paints a rosier picture of system-wide performance than the numbers support. Each of these can give the receiving party a legal basis to unwind the deal, recover compensation, or both. This guide walks through how Ontario law treats each category of misrepresentation, what you must prove, what you can recover, and the practical drafting and due diligence points that commonly decide the outcome.
The Core Elements of a Misrepresentation Claim in Ontario
Whichever category applies, a claim for misrepresentation in Ontario generally requires four building blocks:
- A representation of fact. The statement must be one of existing fact, not mere sales talk (often called "puffery"), opinion, or a forward-looking promise. "This machine produces 500 units an hour" is a statement of fact. "This is the best machine on the market" is opinion.
- Falsity. The statement was untrue when it was made. A statement that becomes incorrect later, without more, is not automatically actionable.
- Materiality and reliance. The statement induced the other party to enter the contract. If the receiving party would have signed anyway, reliance is hard to prove.
- Resulting loss. The misrepresentation caused the receiving party harm, typically a worse bargain, direct financial loss, or consequential damages.
The Supreme Court of Canada set out the modern Canadian framework in Queen v. Cognos Inc., [1993] 1 SCR 87, which remains the leading authority on the tort of negligent misrepresentation and informs how Ontario courts analyze misrepresentation more broadly.
Fraudulent Misrepresentation in Ontario
Fraudulent misrepresentation is the most serious of the three types of misrepresentation in Ontario. It occurs where a party makes a false statement of fact:
- knowing it to be false;
- without honest belief in its truth; or
- recklessly, not caring whether it is true or false.
To succeed in a claim for fraudulent misrepresentation in Ontario, the plaintiff generally needs to establish five elements:
- The defendant made a false representation of fact.
- The defendant knew the statement was false or was reckless as to its truth.
- The defendant made the representation with the intention that it be acted on by the plaintiff.
- The plaintiff relied on the statement.
- The plaintiff suffered damages as a result.
A common scenario is the sale of a small business. The vendor produces financial statements that overstate revenue, conceals a lost customer, or fails to disclose that a major contract is about to end. The purchaser signs based on that picture, takes over the business, and only then discovers the truth.
Entire-Agreement Clauses Do Not Shield Fraud
Most commercial contracts in Ontario contain an "entire agreement" clause saying that the written contract contains everything the parties agreed to and that the buyer is not relying on any statement made outside the four corners of the document. Sellers often assume these clauses are a complete defence.
They are not. In 10443204 Canada Inc. v. 2701835 Ontario Inc., 2022 ONCA 745, the Ontario Court of Appeal confirmed that an entire-agreement clause and the existence of due diligence opportunities cannot bar a claim of fraudulent misrepresentation. The purchasers of a coin laundry business were induced to buy based on statements about profitability and income, and the court was not prepared to let the seller hide behind boilerplate.
Remedies for Fraudulent Misrepresentation
A party who succeeds on fraudulent misrepresentation may obtain:
- Rescission, unwinding the contract and putting the parties back to where they started.
- Damages measured on a tort basis to cover direct and consequential losses.
- Punitive damages in exceptional cases where the conduct was malicious or high-handed.
Negligent Misrepresentation in Ontario
Negligent misrepresentation lies one step below fraud. The representor does not know the statement is false, but was careless in making it, they did not take the trouble to verify facts they were in a position to check.
The modern Canadian test comes from the Supreme Court of Canada's decision in Queen v. Cognos Inc. The plaintiff must establish:
- A special relationship (duty of care) between the representor and the representee.
- A representation that is untrue, inaccurate, or misleading.
- Negligence, the representor did not exercise reasonable care in making the statement.
- Reasonable reliance by the representee.
- Damages caused by that reliance.
These elements matter in everyday commercial practice. Consider a share purchase where the vendor's principal walks the buyer through a forecast that has not been stress-tested, or an asset sale where vendor-provided customer lists include names that have already quietly cancelled. If the seller was in a position to know better and did not, a court may find negligent misrepresentation even without proof of dishonesty.
Common commercial settings include:
- Share purchase agreements and asset sales, especially statements about revenue, EBITDA, customer concentration, or contract renewals.
- Disclosure of financial statements and management forecasts.
- Representations about inventory, equipment condition, or regulatory status.
- Vendor take-back financing arrangements where the vendor's characterization of the buyer's business plan becomes material to the lender.
Remedies for Negligent Misrepresentation
Damages are generally assessed on a tort basis, the court tries to put the plaintiff back in the position they would have been in had the misrepresentation never been made. Rescission may also be available in appropriate cases. Unlike fraud claims, punitive damages are unusual.
Innocent Misrepresentation
Innocent misrepresentation applies when the representor honestly, and reasonably, believed the statement was true. There is no dishonesty and no carelessness; the statement simply turns out to be wrong.
The primary remedy is rescission: the party who relied on the statement can unwind the contract and be restored to their pre-contract position. Damages are typically not available for innocent misrepresentation in Ontario. That is a critical distinction: an innocent misrepresentation may allow you to walk away from the deal, but it usually will not put money in your pocket for losses already incurred.
Rescission is an equitable remedy, and courts can refuse to grant it if:
- the innocent party affirmed the contract after discovering the truth;
- too much time has passed (laches);
- third-party rights have intervened and cannot fairly be unwound; or
- restitutio in integrum, restoring the parties to their original positions, is no longer possible (for example, because the subject matter has been consumed, destroyed, or materially altered).
Remedies for Misrepresentation in Ontario
Rescission
Rescission is the classic contract remedy for misrepresentation. It treats the contract as if it had never been made: property is returned, purchase prices are repaid, and the parties resume their pre-contract positions, with adjustments for use, benefits received, and improvements where appropriate. Rescission is available for all three categories of misrepresentation, but it is subject to the equitable defences above.
Damages
For fraudulent and negligent misrepresentation, damages are assessed on a tort measure, the aim is to restore the plaintiff to the position they would have been in had the misrepresentation not occurred. That is different from the contract measure (putting the plaintiff where they would have been if the contract had been performed as promised), and the difference can matter a great deal in practice. Consequential losses, lost profits, financing costs, remediation costs, can be recoverable where they were reasonably foreseeable.
Punitive Damages
Ontario courts can award punitive damages against a defendant whose conduct was particularly egregious, for example, a sustained course of deliberate deception designed to strip a buyer of their savings. Punitive damages are meant to punish and denounce, not to compensate, and are awarded sparingly.
Key Pitfalls and Protections for Ontario Businesses
Misrepresentation claims are almost always cheaper to prevent than to litigate. Business owners on both sides of a deal can reduce their exposure by following a few practical rules.
Do Real Due Diligence
Buyers should insist on access to source documents, financial statements, customer contracts, supplier agreements, leases, employment records, and should document what was asked for and what was produced. A paper trail showing what the buyer actually saw, and what the seller said about it, is invaluable evidence if a dispute later arises.
Understand What Entire-Agreement Clauses Can and Cannot Do
Entire-agreement clauses are a standard and important part of a well-drafted commercial contract. They help ensure that the final deal is captured on paper and that stray comments made during negotiations are not pulled into the contract's substance. However, as 10443204 Canada Inc. v. 2701835 Ontario Inc. confirmed, they cannot defeat a claim of fraudulent misrepresentation. Sellers who believe a boilerplate clause protects them from pre-contract dishonesty are mistaken.
Representations vs. Warranties
In a typical share purchase agreement or asset purchase agreement, the vendor gives both representations (statements of existing fact, which can ground a misrepresentation claim if untrue) and warranties (contractual promises about the state of the business, which ground a breach-of-contract claim if untrue). Many clauses combine the two. The distinction matters for choosing the right remedy, the applicable measure of damages, and any survival and indemnity provisions.
Use Disclosure Schedules and Survival Clauses
Well-drafted agreements include detailed disclosure schedules that carve out known exceptions to the reps and warranties; survival clauses that say how long the reps and warranties live past closing; materiality thresholds and basket/cap limits on indemnity claims; and specific indemnity language dealing with breach of reps and warranties. These provisions allocate risk predictably and reduce the chance that a minor issue becomes a full misrepresentation fight.
Limitation Periods for Misrepresentation Claims in Ontario
Under the Limitations Act, 2002, SO 2002, c. 24, Sch. B, most civil claims in Ontario, including claims for misrepresentation, are subject to a basic two-year limitation period (s. 4) that runs from the date the claim was discovered or reasonably ought to have been discovered.
Two-year running time is not always triggered on the day the contract was signed. The Limitations Act, 2002 applies a discoverability rule (s. 5): the clock generally starts when the injured party knew, or with reasonable diligence ought to have known, the material facts underlying the claim.
There is also an ultimate limitation period of fifteen years (s. 15), running from the day the act or omission took place, regardless of when it was discovered. Certain exceptions apply, including for acts that were wilfully concealed, so actively hidden fraud may extend the clock, but these are narrow. Because the rules are fact-specific and missing the limitation period is usually fatal to a claim, parties who suspect a misrepresentation should seek advice promptly rather than waiting.
Frequently Asked Questions
What are the three types of misrepresentation in Ontario contract law?
Ontario law recognizes fraudulent misrepresentation (a knowingly false or reckless statement), negligent misrepresentation (a careless false statement made without reasonable verification), and innocent misrepresentation (a false statement the representor honestly and reasonably believed to be true). Each category has different elements and different available remedies.
What is the difference between fraudulent and negligent misrepresentation?
Fraudulent misrepresentation requires dishonesty, knowledge of falsity or recklessness as to truth. Negligent misrepresentation requires only carelessness: the representor failed to exercise reasonable care in confirming the statement was true. Punitive damages are available for fraud but rarely for negligence, and the evidentiary burden for proving fraud is substantially higher.
What remedies are available for misrepresentation in Ontario?
Rescission (unwinding the contract) is available for all three categories. Damages on a tort basis are available for fraudulent and negligent misrepresentation but generally not for innocent misrepresentation. Punitive damages may be awarded in rare cases of particularly outrageous fraudulent conduct.
Can an entire-agreement clause prevent a claim for misrepresentation?
An entire-agreement clause can limit reliance on pre-contract statements in many situations, but it cannot bar a claim of fraudulent misrepresentation. In 10443204 Canada Inc. v. 2701835 Ontario Inc., 2022 ONCA 745, the Court of Appeal confirmed that neither an entire-agreement clause nor the availability of due diligence shields a party that deliberately misled the other side.
What is the limitation period for a misrepresentation claim in Ontario?
The basic limitation period is two years from discovery under section 4 of the Limitations Act, 2002, with an ultimate limitation period of fifteen years under section 15. Time runs from when the injured party knew or ought to have known the claim existed, and may be postponed where fraud was actively concealed.
Does misrepresentation have to be in writing?
No. A misrepresentation can be oral, written, or made through conduct. Oral misrepresentations are harder to prove in court because they depend on witness evidence, which is one reason the best protection is to insist that important pre-contract statements be recorded in the written agreement as representations and warranties.
What is the test for negligent misrepresentation in Canada (the Cognos test)?
The Supreme Court of Canada set out five elements in Queen v. Cognos Inc., [1993] 1 SCR 87: a special relationship between the parties, an untrue or misleading representation, negligence in making it, reasonable reliance by the receiving party, and damages caused by that reliance. All five elements must be proven on a balance of probabilities.
Can silence or non-disclosure amount to misrepresentation?
Generally, contracting parties in Ontario do not owe a broad duty to volunteer information, but silence can amount to misrepresentation where there is a duty to speak, for example, where partial disclosure creates a misleading picture, where a statement that was true when made later becomes false, or where a fiduciary or other special relationship imposes a duty of candour.
