@wanton: Honestly if you live in Toronto, it's not even needed. As traffic dt is ridiculous and the public transit is fine. Sauga and Brampton have a good transit system as well. It's only during cold weather that a car really comes in handy, and to save time. But with car cost, insurance, gas, maint, it really isn't worth it to a lot of people.
i got my full license maybe near the end of sophomore year of high school or it could've been the summer going into junior year, not exactly sure. in the end it only mattered my senior year of high school because that's when i had my own car and could drive it around freely
