Since you live in Ontario get a Vehicle Information Package to verify ownership:

This is from the Ontario web site:
What is a Used Vehicle Information Package?
The package, which the seller must show to potential buyers and give it to the buyer of the vehicle, costs $20 and includes the following:
1. Description of the vehicle
2. Ontario vehicle registration history
3. Odometer Information
4. If there are any liens registered against the vehicle
5. Wholesale and retail values for the vehicle's model and year (on which the minimum tax payable may apply), if available
6. Retail sales tax requirements
7. Bill of sale
8. Other information such as consumer tips on vehicle safety standards inspections
Good luck.
