You bought the business, and the numbers turned out to be fiction. A claim for fraudulent misrepresentation in Ontario exists precisely for that situation, and it reaches further than an ordinary breach of contract claim. However, the law sets a demanding standard, and the clock starts running sooner than most people assume. This guide explains what you must prove, what you can recover, and how quickly you need to move.
What Counts as Fraudulent Misrepresentation in Ontario
Courts use three labels interchangeably: civil fraud, deceit, and fraudulent misrepresentation. Ontario judges apply the same four-part test to all of them.
Fraudulent misrepresentation in Ontario is a tort rather than a mere breach of contract, so the claim survives many contractual defences a seller would otherwise raise.
The Supreme Court set that test out in Bruno Appliance and Furniture, Inc. v. Hryniak, 2014 SCC 8. Karakatsanis J. set out the elements at paragraph 21:
(1) a false representation made by the defendant; (2) some level of knowledge of the falsehood of the representation on the part of the defendant (whether through knowledge or recklessness); (3) the false representation caused the plaintiff to act; and (4) the plaintiff’s actions resulted in a loss.
Element three defeats many claims. Proving that someone lied is not enough; you must also show the lie induced you to act.
A vendor overstates monthly revenue, the buyer relies on those figures to set the price, and the buyer closes. All four elements are then in play.
Fraudulent misrepresentation claims in Ontario frequently founder on inducement rather than falsity. Where the buyer commissioned its own valuation and ignored the vendor’s numbers, causation becomes hard to establish.
Who you can sue
A corporate seller is rarely the only defendant. Because deceit is a tort, the individual who made the statement can be personally liable despite the corporate structure. You must plead that person’s own conduct with particularity, though, since courts strike bare allegations against directors and officers.
That drives strategy in Ontario fraudulent misrepresentation cases. A judgment against an empty holding company is worth little; one against the principals who signed the financial statements may be worth a great deal, assuming they are solvent.
Fraudulent, Negligent and Innocent Misrepresentation
Not every false statement amounts to fraud. Ontario law separates fraudulent misrepresentation from negligent and innocent misrepresentation by the speaker’s state of mind, and the category shapes every remedy that follows.
Fraudulent misrepresentation requires knowledge of the falsehood, absence of honest belief, or recklessness about the truth. Negligent misrepresentation involves an honest belief held carelessly. Innocent misrepresentation involves an honest and reasonable belief that turned out to be wrong.
The negligent misrepresentation test
For negligence, the Supreme Court’s decision in Queen v. Cognos Inc., [1993] 1 SCR 87, supplies five requirements: a duty of care arising from a special relationship, an untrue or misleading representation, negligence in making it, reasonable reliance by the representee, and resulting damage.
Consequently, many plaintiffs plead fraud and negligence in the alternative. If the court cannot find intent, the negligence claim may still succeed.
Why the label matters
Fraud unlocks remedies that negligence does not. It supports punitive damages, survives clauses designed to block claims, and can extend limitation periods where the wrongdoer concealed what happened.
Innocent misrepresentation, by contrast, generally supports rescission alone.
Why an Entire Agreement Clause Won’t Save the Seller
Almost every purchase agreement contains an entire agreement clause stating that no representations exist outside the document. Sellers treat it as a shield.
Ontario’s Court of Appeal has said otherwise, repeatedly, and that is why an entire agreement clause rarely ends a fraudulent misrepresentation claim. In 10443204 Canada Inc. v. 2701835 Ontario Inc., 2022 ONCA 745, the sellers of a coin laundry sued on a vendor take-back mortgage. The buyers counterclaimed, alleging misstated gross revenues, and the motion judge treated the entire agreement clause as a complete answer. The Court of Appeal reversed.
The reasoning is direct. Such a clause cannot deny an innocent party a remedy for fraudulent misrepresentation, and Ontario courts will not read it that way. Unequal bargaining power is not required either.
Just as importantly, the same decision confirms that a contractual opportunity to conduct due diligence does not strip a purchaser of the right to avoid a contract for fraud.
The Court took a similar line in Royal Bank of Canada v. 1643937 Ontario Inc., 2021 ONCA 98, where guarantors said the bank had misdescribed their liability limit. An entire agreement clause did not preclude the misrepresentation defence there either.
For buyers, that line of authority is the most useful feature of a fraudulent misrepresentation claim in Ontario. Boilerplate that defeats a contract claim will not necessarily defeat a fraud claim.
Silence, Non-Disclosure and Hidden Defects
The general rule is straightforward. Mere silence is not a misrepresentation, and parties at arm’s length must protect their own interests.
Several exceptions matter in practice, though. Ontario recognises a defined set of circumstances in which staying quiet amounts to fraudulent misrepresentation.
When silence becomes actionable
Half-truths are the most common exception. Once you speak, you must speak fully, because a technically accurate statement creating a false impression is actionable.
A direct question compels a complete and honest answer. In addition, where a representation was true when made but became false before closing, the speaker must correct it.
Active concealment counts as well, since papering over a defect converts a discoverable problem into an actionable misrepresentation.
Finally, fiduciary and special relationships carry disclosure duties. Partners, directors, agents and trustees cannot simply stay quiet.
Patent and latent defects in real estate
Real estate transactions account for a large share of fraudulent misrepresentation litigation in Ontario, and property deals follow a parallel structure. Patent defects, which a reasonable inspection would reveal, are subject to the caveat emptor or “buyer beware” rule, so a seller need not mention them. Active concealment defeats that protection even in an “as is” sale.
Latent defects are different, although buyer beware remains the starting point. Ontario authority accepts that a vendor who knows of a latent defect rendering premises unfit for habitation may owe a duty to disclose it. The purchaser must prove the vendor actually knew, however, which makes the exception demanding.
Voluntary disclosure changes the analysis. In Krawchuk v. Scherbak, 2011 ONCA 352, the Court of Appeal applied the Cognos test to statements a vendor made in a seller property information statement. Once you complete such a form, your answers can be used in a claim against you if they are found to be false.
The overlapping duty of honest performance
Since Bhasin v. Hrynew, 2014 SCC 71, and C.M. Callow Inc. v. Zollinger, 2020 SCC 45, contracting parties owe a duty of honest performance. Silence, omissions and half-truths can breach that duty where a party knowingly misleads its counterparty.
Remedies and Deadlines in a Fraudulent Misrepresentation Ontario Claim
A successful fraudulent misrepresentation claim in Ontario opens two doors: unwind the deal, or keep it and sue for the shortfall.
Rescission
Rescission unwinds the contract and restores the parties to their pre-contract positions, with adjustments for benefits received. It is discretionary, however, so several bars apply.
Affirmation is the first: a party who continues performing after learning the truth may lose the right. Delay, third party rights, and the impossibility of restoring the parties are the others.
The third party bar is softer than it looks. In Urban Mechanical Contracting Ltd. v. Zurich Insurance Company Ltd., 2022 ONCA 589, the Court of Appeal put it this way at paragraph 5:
Prejudice to the rights of third parties may be, but is not always, a bar to rescission. This is particularly true in the case of fraudulent misrepresentation and in cases where it is possible to provide restitution in other ways.
The court left the final assessment to a trial judge.
Damages
Damages in deceit follow the tort measure. They put you where you would have been had the misrepresentation never been made, not where you would have been had it been true.
That distinction matters. A buyer who overpaid recovers the money and consequential losses flowing from the fraud, not the profits of the business they were promised.
Punitive damages are available as well. Under Whiten v. Pilot Insurance Co., 2002 SCC 18, they require conduct that is malicious, oppressive and high-handed, departing markedly from ordinary standards of decent behaviour. They also require an independent actionable wrong, which deceit itself supplies.
Limitation periods
Timing defeats more fraudulent misrepresentation claims in Ontario than the merits ever do. The Limitations Act, 2002 imposes a basic two-year period running from discovery, not from the date of the lie.
Discovery occurs when you knew, or ought reasonably to have known, that loss occurred, that an act or omission caused it, that the defendant was responsible, and that a proceeding would be appropriate. The Act presumes you knew on the day the act occurred unless you prove otherwise.
Section 15 adds an ultimate 15-year period. Willful concealment suspends that outer clock, and it can also delay discovery under the two-year rule by helping to rebut the presumption.
Ontario courts apply these limitation rules to fraudulent misrepresentation as they do to any other tort. Timing arguments therefore turn on when you first had reason to investigate, so build that record early.
Ontario’s Limitations Act, 2002 rewards a careful read. Do not assume that discovering a fraud years later preserves your claim.
What to Do Next: When to Call a Lawyer
Practical steps matter more than legal theory here. Anyone weighing a fraudulent misrepresentation claim in Ontario should work through the following sequence first.
Preserve everything first. Collect the offer, the agreement, financial statements, emails, texts, marketing materials and notes of what the other side said. Fraud cases turn on contemporaneous documents.
Next, stop performing carefully rather than abruptly. Continued performance can amount to affirmation, although sudden non-payment can put you in breach, so get advice first.
Then move quickly if you suspect dissipation. A Mareva injunction can freeze assets, although the threshold is high: a strong prima facie case, assets within the jurisdiction, a real risk of dissipation, and full and frank disclosure on an urgent motion usually brought without notice.
You must also undertake to pay damages if the freeze proves unjustified. Norwich orders can trace where money went, and a certificate of pending litigation may be available where the claim asserts an interest in land.
Two points that surprise clients
Pleading rules are strict. Rule 25.06(8) of the Rules of Civil Procedure requires full particulars wherever a party alleges fraud or misrepresentation, although knowledge may be pleaded as a fact without the circumstances behind it.
Case law fills in what particulars means: what was said, when, where, by whom, to whom, why it was false, and how it induced you. Courts strike bare allegations of dishonesty.
The standard of proof, by contrast, is not special. In F.H. v. McDougall, 2008 SCC 53, Rothstein J. was emphatic at paragraph 40:
Like the House of Lords, I think it is time to say, once and for all in Canada, that there is only one civil standard of proof at common law and that is proof on a balance of probabilities.
Fraud is harder to prove in practice, because it requires proof of someone’s state of mind, but no higher legal test applies.
In Hryniak v. Mauldin, 2014 SCC 7, the Supreme Court called for change at paragraph 2:
Increasingly, there is recognition that a culture shift is required in order to create an environment promoting timely and affordable access to the civil justice system.
Summary judgment is therefore available in fraud cases, so a well-documented claim need not wait years for trial.
Related claims worth pleading
A fraudulent misrepresentation claim in Ontario rarely travels alone. Where the deception happened inside a corporation, the oppression remedy under section 248 of the Business Corporations Act may give a shareholder or director a broader answer.
Where the money can still be traced, a constructive trust over the proceeds can put you ahead of ordinary creditors. Unjust enrichment, breach of fiduciary duty and conspiracy also appear regularly alongside a fraudulent misrepresentation claim in Ontario.
Raise these possibilities with counsel at the outset, because amendments cost time and a limitation period may have closed.
Business fraud rewards fast, organised responses and punishes hesitation. If you suspect fraudulent misrepresentation in an Ontario business deal, or someone has accused you of it, contact Cowan for a clear-eyed assessment of the claim and the deadlines you face.
