There are no more unlimited carfax accounts by vin anymore, so unless someone bought 5 and have unused ones you aren't going to get a free carfax. Carfax isn't that great for Canadian cars anyways.
Carproof is what you want, they have the best info for Canadian cars, but they are even harder to come by cause they are ordered by vin and they never had an option to run unlimited vin checks.
Attached is a free AutoCheck report, but beware I've seen many clean AutoChecks where Carproof showed an accident. If you are serious about the car, pay to get the Carproof.
