Are there disclosure requirements for sellers in Ontario?

Must-Know: Are sellers in Ontario required to disclose property defects? Here's the blunt truth.

Quick answer

Yes. Ontario sellers must disclose known material defects and cannot hide problems that would affect a buyer’s decision. There is no single government “seller disclosure” form required across the province, but the legal duty to be honest is real — and the cost of hiding issues can be severe.

What Ontario law actually requires

• Common law duty: Sellers must not fraudulently conceal latent defects (hidden problems that affect safety, use, or value). If you know about a structural issue, mould, sewage backup, illegal additions, or contamination, you must disclose it.
• REBBA and registrant duties: Real estate professionals in Ontario must disclose material facts to buyers and sellers. If an agent knows a problem, they must pass it on.
• “As-is” clauses don’t excuse fraud: Advertising a sale “as-is” won’t protect a seller who actively hides known defects.
• New homes and Tarion: New home buyers are covered by Tarion warranty rules. That’s separate from resale seller duties.

Examples of material issues to disclose

• Structural cracks, foundation problems, water penetration
• Past or present mould or pest infestations
• Illegal or unpermitted additions
• Sewage, septic, well problems
• Environmental contamination or prior remediation
• Outstanding municipal work orders or zoning violations

Practical implications for sellers

If you’re selling in Ontario, follow this checklist:

• Be honest about what you know. Don’t wait for a buyer to uncover it.
• Keep records: inspection reports, repair invoices, permits, receipts.
• Consider completing a Property Disclosure Statement (PDS) even though it’s optional — it reduces disputes.
• Allow reasonable access for buyer inspections and consider pre-listing inspections.
• Consult a real estate lawyer on complex issues (title defects, easements, encroachments).

Consequences of non-disclosure Buyers can sue for misrepresentation, rescission (contract cancelled), or damages. A seller who hides defects risks having a sale reversed or paying large settlements. Criminal fraud charges are rare but possible in extreme cases.
