What must you disclose when selling a house in Ontario? A seller should not conceal defects or make misleading statements, and certain known hidden defects may require disclosure. The answer depends on the nature of the problem and the facts—not a blanket rule that every repair or past issue must be reported. This guide explains patent versus latent defects, past water or structural problems, stigmas and property information statements, with guidance on when to consult an Ontario real-estate lawyer.
RECO explains that a seller’s legal disclosure obligations are based on current case law rather than TRESA itself. Because this area can be complex, sellers should obtain legal advice when they are unsure whether a particular fact or defect must be disclosed.
Patent Defects vs. Latent Defects
RECO separates property defects into two broad categories.
- Patent defects are defects a potential buyer or home inspector could detect through reasonable observation and inquiry.
- Latent defects are generally not apparent through reasonable inspection and can involve conditions that make a property unfit for habitation, dangerous or potentially dangerous.
RECO’s current bulletin says a seller generally does not have to proactively disclose a patent defect, but the seller should not conceal it or misrepresent the property. RECO also states that latent defects must be disclosed and recommends legal advice where there is uncertainty about whether a particular issue meets that threshold.
See RECO’s Bulletin 7.4: Facts a seller has a legal obligation to disclose.
Do Not Hide or Cover Up a Known Problem
Trying to conceal a visible defect can create additional risk. Painting over active water damage, blocking access to a known issue or making statements that create a misleading impression can undermine a seller’s ability to rely on “buyer beware.”
What About Past Water, Structural or Mechanical Issues?
The answer depends on the facts. A fully repaired historical issue may be different from an unresolved hidden condition that could create danger or make the property unfit for habitation. Keep invoices, warranties, reports, permits and remediation records where available, and discuss uncertain situations with your lawyer before marketing the property.
What If an Inspection Finds Something Before You List?
A pre-listing inspection can give a seller useful information, but learning about an issue can also create decisions about repair, pricing, disclosure and documentation. Do not assume that fixing an issue automatically eliminates every disclosure question, or that leaving it unrepaired automatically means the property cannot be sold.

What About Stigma?
A stigma is different from a physical defect. RECO notes that Ontario sellers are generally not required to proactively disclose facts that may create a stigma for some buyers, but stigma can be highly fact-specific. RECO advises seller representatives to discuss stigma issues with the seller and recommend legal advice where appropriate.
See RECO’s Bulletin 7.5: Stigmas.
Property Information Statements Are a Separate Decision
RECO explains that a seller may complete a property information statement for different purposes. A statement intended only to help the seller’s representative understand the property is different from one intended to be shared with buyers. If a seller prepares a statement for buyers, the representative must disclose that the statement exists to interested buyers and provide it when requested.
See RECO’s Property Information Statements guidance.
Listing Information Must Also Be Accurate
Disclosure is not only about defects. Property descriptions, renovation dates, permits, legal status, taxes, condo fees and other factual claims should be accurate. RECO has specifically warned registrants to verify property details and avoid publishing information that cannot be confirmed.
Can You Sell a House As-Is?
Yes, a property can be marketed in as-is condition, but “as-is” wording does not give a seller permission to conceal, misrepresent or ignore legal disclosure obligations. The clause also does not eliminate the importance of accurate marketing and appropriate legal advice.
