Ontario used car problems after purchase: dealer disputes, refunds & OMVIC
If an Ontario registered dealer refuses a refund or you discover a problem after purchase, the refusal does not by itself decide your rights. There is no general cooling-off period, but dealer disclosure duties matter and specified missing or inaccurate information can create a 90-day cancellation right.

What the law says
- Ontario says there is no general cooling-off period for motor-vehicle contracts; a signed deal is usually binding.
- Registered dealers must disclose prescribed vehicle history and key information in writing.
- Ontario Regulation 333/08 section 50 allows cancellation within 90 days after actually receiving the vehicle for specified disclosure failures, including prescribed odometer/distance information, make/model/model year, branding and specified prior use. This is not a general 90-day return right.
- Dealer advertisements that state a vehicle price must generally use all-in pricing for the fees and charges the dealer intends to collect. HST and the actual cost of licensing/registration may be excluded if the advertisement clearly states they are not included.
- The Motor Vehicle Dealers Compensation Fund can cover qualifying losses from registered-dealer transactions, subject to eligibility and claim rules.
What to do next
- 1Confirm the dealer and salesperson were registered with OMVIC.
- 2Keep the signed bill of sale, all disclosure statements, advertisement, vehicle-history material and finance documents.
- 3Compare required disclosures with the actual vehicle history and preserve proof of any discrepancy.
- 4If a statutory cancellation ground may exist, act promptly and document the notice rather than relying on a verbal conversation.
- 5Complain to OMVIC where a registered dealer or salesperson may have breached the regulatory framework.
- 6For substantial damages or overlapping Consumer Protection Act issues, consider qualified Ontario legal advice.
What if the dealer refuses a refund?
Ontario does not give every vehicle buyer a general right to return a car simply because a problem appears or the buyer changes their mind. But a dealer saying “no refund” does not end the analysis. Check whether the problem involves a required disclosure, inaccurate vehicle history, false or deceptive information, a warranty or another contractual or statutory remedy.
No general cooling-off period
Ontario warns consumers that motor-vehicle contracts do not have a general cooling-off period. Changing your mind or finding a better deal does not normally cancel a signed agreement.
90-day cancellation for specified disclosure failures
Ontario Regulation 333/08 section 50 creates a specific cancellation remedy for listed disclosure failures in registered-dealer transactions. The regulation says this cancellation cannot be exercised more than 90 days after the buyer actually receives the vehicle. The listed grounds include prescribed distance/odometer information, make/model/model year, branding and specified prior use such as rental, taxi, limousine, police or emergency service. It is not a blanket 90-day refund or change-of-mind period.
Dealer misrepresentation and disclosure disputes
The Motor Vehicle Dealers Act prohibits registered dealers from falsifying information and from furnishing false or deceptive information about a motor-vehicle trade. Preserve the advertisement, bill of sale, vehicle-history material and the exact representation you say was wrong or omitted.
Dealer disclosure duties
The Motor Vehicle Dealers Act and regulation require registered dealers to provide extensive written information about used vehicles. The sale contract should be preserved because it is the primary record of what the dealer disclosed.
All-in pricing
If an Ontario dealer advertisement includes a vehicle price, that price must generally include the fees and charges the dealer intends to collect. HST and the actual cost of vehicle licensing/registration may be left out only where the advertisement clearly states they are not included. Evidence of the advertised price and final bill of sale can therefore be central in a fee dispute.
OMVIC and the compensation fund
OMVIC regulates registered dealers and salespeople and receives consumer complaints. Ontario also maintains a Motor Vehicle Dealers Compensation Fund for qualifying losses when a registered dealer fails in specified ways.
Private sellers and curbsiders
Private purchases do not receive the same OMVIC dealer protections. Ontario warns about curbsiders—unregistered dealers posing as private sellers—and requires private sellers to provide a Used Vehicle Information Package.
