Dealers and salespeople should reveal everything they know about the vehicles they are selling, even if the customer doesn’t ask. If the dealer or salesperson had no knowledge of a problem, the dealer can still be held liable if they should have known.
If the dealer unknowingly breaches the CPA, the consumer is still fully entitled to the protection of the CPA. For example, the dealer buys a used vehicle at fair market value with 52,000 km on it and sells it to a consumer. A month later, the consumer discovers the odometer had been rolled back by a previous owner. Even though the dealer did not know about the roll back, and bought and sold in good faith, the consumer is protected by the Act and may request cancellation of the contract or negotiate other compensation.
