Key takeaways
  • Ontario follows buyer beware, so a seller generally need not disclose patent defects that a buyer could find through reasonable inspection and inquiry.
  • A seller must disclose latent defects that make the property unfit for habitation, dangerous or potentially dangerous.
  • A seller who conceals a patent defect can lose the protection of buyer beware.

You have found a leak, a cracked foundation or an old repair nobody mentioned, and you are looking at the agreement of purchase and sale for what it says about the property's condition. Words like "as is" or a seller warranty can feel decisive, but they are only part of the picture.

This article explains the general rules in Ontario on defects, what counts as latent, and how the wording of your agreement fits in. The outcome in your case depends on the exact clauses and facts, so a lawyer should review them.

Buyer beware in Ontario

Ontario follows "buyer beware". A seller generally need not disclose patent defects, which a buyer can find through reasonable inspection and inquiry. These duties come from case law, not TRESA.

In plain terms, the law expects you to look carefully and ask questions. That is why buyers commonly look at inspection conditions before the deal is firm. Whether your agreement gives you time to inspect, and how long, depends on its exact wording, so read the conditions closely and confirm with a lawyer before you waive anything.

Patent and latent defects

The difference between the two types of defect drives most disputes.

TypeGeneral rule
Patent defect (found by reasonable inspection and inquiry)Seller generally need not disclose it
Latent defect making the property unfit for habitation, dangerous or potentially dangerousSeller must disclose it
Patent defect the seller concealsSeller can lose the protection of buyer beware
Latent defect not disclosedMay be treated as misrepresenting the property

Wilful blindness can also create liability. A seller cannot avoid the issue by deliberately not looking at a problem they suspect.

Telling the two types apart is not always easy. A crack you can see from the basement may be one thing, while water damage hidden behind a finished wall may be another. Which category your problem falls into depends on the facts, so it is worth confirming with a lawyer.

What "as is" and warranties do

Agreements often include wording about the property's condition, such as an "as is" statement, or a seller warranty about things like chattels or known problems. What these clauses mean, and how far they limit your rights, depends on the exact words in your agreement and the facts. Read them closely and have a lawyer explain them before you sign.

Be careful about assuming that wording alone protects a seller from a hidden, dangerous defect or a deliberate misstatement. The case law duties in the previous section still matter, and concealment and misrepresentation can change the result.

The seller information statement

A seller property information statement is not a required form. A seller's agent may ask the seller to complete one, and it is based on the seller's own knowledge and experience.

If a seller has prepared an information statement for buyers, the seller's agent must tell every interested buyer that it exists, and must give a copy to any buyer who asks. If you received one, keep it. Compare what it says with your inspection findings, because a statement that does not match what you find may matter later.

What to do next

None of these steps decides who is responsible. They keep your options open and give a lawyer what is needed to look at your situation properly.

Frequently asked questions

Does "as is" mean I have no rights?

Not automatically. What an "as is" clause does depends on its exact wording and the facts, and a seller who conceals a patent defect can lose the protection of buyer beware. Have a lawyer read the clause.

What is a latent defect?

It is a defect a buyer could not find through reasonable inspection and inquiry. A seller must disclose latent defects that make the property unfit for habitation, dangerous or potentially dangerous.

Do sellers have to complete an information statement?

No, it is not a required form. A seller's agent may ask the seller to complete one. If one exists, the agent must tell interested buyers and give a copy to any who ask.

Can I walk away if I find a defect before closing?

It depends on your conditions and the wording of your agreement. Whether you can end the deal turns on which conditions are still open and what the seller knew or disclosed. A seller who conceals a patent defect can lose the protection of buyer beware. Speak to a lawyer before you waive anything or refuse to close.
