I can't rent a car because my licence is a G2.
The Canadrian driving system works like this:
G1: Your first license lets you drive if someone else is in the car who has a G licence. You cannot leave the country or have any alcohol in your bloodstream.
G2: You can drive on your own, but you cannot leave the country or have any alcohol in your bloodstream.
G: You can drive on your own, leave the country, teach other people to drive and have a small ammount of alcohol in your bloodstream
My G test is in March (the Ministry of Transportation here went on strike twice, so theres like an 8 month waiting period for tests).
