If you don't possess a driver's license issued in Canada, then you may need to acquire an International Driving Permit (IDP) in your home country to be allowed to rent a car. Also consider that if an IDP is required, it won't be valid on its own. You'll need to show your current license your passport and other forms of ID as well. Lastly, it's important that the credit card used to book the rental vehicle matches the name on your license and passport. Some added requirements to rent a car internationally are:

• Age restrictions: You'll need to be 25 or over in many countries to rent a car. If you're younger than that, it might still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to the types of cars you can rent.
• Driving limitations: Be sure to read the rules and regulations before sliding behind the wheel. You typically can't cross country borders, drive onto ferries or go off-roading with a rental car.
