You need a valid driver's license and proof of auto insurance to drive a car in Canada. A driver's license and insurance from the United States are also valid in Canada for a short while (up to 90 days in some provinces). However, visitors from other countries are advised to get an International Driving Permit (IDP) and will need to purchase insurance to rent a car.

If you already have auto insurance in the United States and are coming to Canada on a tourist visa, it is very likely that your existing policy will cover you. However, it is a good idea to call your insurance provider to make sure.
