Seller Misrepresentation and Non-Disclosure in Ontario Home Sales

You close on a house, move in, and discover something the seller clearly knew — a history of flooding, a roof that was patched but never repaired, a toxic mold problem behind freshly painted drywall. Or maybe the seller told you something during negotiations that you later find out was simply false. Either way, you may be dealing with seller misrepresentation or non-disclosure in Ontario, and you may have a legal claim.

These cases are among the most common — and most frustrating — real estate disputes Ontario buyers face after closing. This article explains the legal framework, what you need to prove, and what you can realistically recover.

Two Separate Legal Concepts

Misrepresentation

A misrepresentation is a false statement of fact made by the seller (or seller's agent acting on their behalf) that induced you to buy the property or to buy it at the price you paid. There are three main types:

• Fraudulent misrepresentation: the seller knew the statement was false (or was reckless about the truth)
• Negligent misrepresentation: the seller made a careless false statement without taking reasonable care to verify it
• Innocent misrepresentation: the statement was false but the seller genuinely believed it to be true

The type matters because it affects what damages you can claim and whether you can rescind (unwind) the contract.

Non-Disclosure

Non-disclosure is different — it is not about a false statement but about silence. In Ontario, sellers have a legal duty to disclose latent defects they know about, but not patent defects.

• A latent defect is one that is hidden, not discoverable by a reasonable inspection, and that renders the property dangerous or unfit for habitation. A flooded basement that the seller covered with new drywall and fresh paint is a classic example.
• A patent defect is one that a buyer could have discovered through a reasonable inspection. If the crack in the foundation wall was clearly visible during your walkthrough, the seller may argue they had no duty to call it out.

The rule "buyer beware" (caveat emptor) still applies in Ontario, but it has meaningful limits: it does not protect a seller who actively conceals a known defect, who makes fraudulent statements, or who fails to disclose a defect that makes the property uninhabitable.

What You Need to Prove

The elements of a successful claim vary by the type, but in general you must show:

1. The seller knew (or should have known) about the defect or made the false statement
2. You relied on the statement or the seller's apparent disclosure — you would have walked away or paid less if you had known the truth
3. You suffered a measurable loss — the cost of repairing the defect, or the difference between what you paid and what the property was worth with the defect known

Documentation is everything: home inspection reports, contractor repair estimates, any written communications from the seller or agent, the Seller Property Information Statement (if one was provided), and the agreement itself.

The Seller Property Information Statement (SPIS)

Many sellers in Ontario provide a Seller Property Information Statement — a form on which the seller answers questions about the property's condition, history of flooding, permits, known defects, and more. The SPIS is not legally required, but if one was provided and contains false answers, it creates strong evidence of misrepresentation.

However, the SPIS typically contains a disclaimer saying the seller is not making a warranty. Courts have nonetheless found liability based on false SPIS answers, particularly where the misstatement was about something the seller clearly knew about (e.g., answering "no" to "has the basement ever flooded?" when the seller had insurance claims for multiple floods).

Remedies: What Can You Get?

Rescission

Rescission means unwinding the deal — you get your money back and return the property to the seller. Courts grant rescission in cases of serious fraudulent misrepresentation or where a latent defect is so significant that the buyer would never have purchased. It is a drastic remedy and not always available, particularly if you have significantly changed the property.

Damages

More commonly, buyers recover monetary damages: the cost to remediate the defect, or the reduction in market value the defect represents. If the seller committed fraud, additional punitive damages may be available in egregious cases.

Agents and Brokerages

If the seller's real estate agent made or repeated the false statement — or knew of the defect and failed to disclose it — you may have claims against them as well, under the common law and under Ontario's real estate legislation. Real estate agents have professional obligations to buyers even when they represent the seller.

Time Limits

Ontario's standard limitation period is two years from when you discovered (or ought reasonably to have discovered) the defect or misrepresentation. For hidden defects, the clock generally starts when you actually found the problem — not on closing day. However, do not delay: evidence degrades, witnesses forget, and legal proceedings take time.

Get a written repair estimate as soon as you discover the problem, and consult a lawyer before undertaking major repairs that might affect your evidence.

Practical Realities

Not every post-closing disappointment is a legal claim. Normal wear and tear, problems you could have found with a proper inspection, and features that simply didn't live up to your expectations are generally not recoverable. A claim requires a specific false statement or a hidden defect the seller knew about.

Before spending money on litigation, discuss with your lawyer whether the provable damages justify the cost. For smaller claims, Ontario's Small Claims Court (up to a threshold — verify the current limit) offers a faster and cheaper path than Superior Court.
