Out of province or out of country driver’s licenses are only valid for 90 days after entering Ontario. After 90 days, your license is considered expired. Anyone with an expired license will not be allowed to drive a Muskoka Woods vehicle, purchase a vehicle while in Ontario, or legally be permitted to drive a friend’s car.
If you are planning to stay in Ontario longer than 90 days and want to drive, we recommend that you obtain an International Driving Permit that allows you to drive up to 1 year while in Ontario. It’s important to note, you cannot obtain the IDP in Ontario, you must get it in the country/province that your license was issued in.
