Just wanted to know if I can legally drive a car in Toronto, Canada on an Australian drivers license?
Yes, if you are just visiting and not becoming a resident of Ontario. In addition, depending on your length of visit, you may need an International Drivers' Permit in addition to your Australian licence. From the Ontario Ministry of Transportation:
Visiting: less than 3 months
If you are visiting Ontario for less than 3 months and want to drive while you're here, you can use a valid driver's licence from your own province, state or country.
You will also need to:
- be at least 16 years old
- have proper insurance coverage for the vehicle you will drive
- carry an original (or exact) copy of the vehicle ownership permit
- obey traffic laws, drive safely and avoid collisions when you drive
Visiting: more than 3 months
If you will be visiting from another country for more than 3 months, you will need an International Driver's Permit (IDP) from your own country.
This is a special licence that allows motorists to drive internationally when accompanied by a valid driver’s licence from their country.
You need to have this permit with you when you arrive in Ontario. You cannot apply for one once you are here.
