Can I sue a private seller for hidden defects on a used car in small claims court?

What the Law Says

In Canada, private used car sales are governed by provincial consumer protection and sale of goods laws—not federal legislation—so rules vary slightly by province. While 'as is' sales are common, sellers still cannot commit fraud or misrepresent facts.

Private sellers in Canada are not covered by provincial consumer protection acts the way dealers are (e.g., Ontario’s Consumer Protection Act, 2002 does not apply to one-time private sales), but they remain bound by the common law of contract and provincial Sale of Goods Acts.

Under section 14 of the federal Sale of Goods Act (R.S.C., 1985, c. S-1), which applies unless excluded by agreement, there is an implied condition that goods sold must be of merchantable quality—but this only applies when the seller is acting in the course of business, not in private sales.

However, a private seller can still be liable for fraudulent misrepresentation or negligent misstatement: if they knowingly hid a defect (e.g., water damage, frame rust, or non-operational airbags) or lied about maintenance history, courts may award damages under tort or equitable principles.

Statutory Text

Where the seller makes a false statement of fact to the buyer which induces the buyer to enter into the contract, the buyer may rescind the contract or claim damages.

— Sale of Goods Act, R.S.C., 1985, c. S-1, s. 13(1)(a)
