When I was a student in Rimouski, I didn't get my driver's licence until much later on. Mr. Lukiwski said that only 2% of Canadians don't a have driver's licence. I was told that 25% of people living in the Toronto area don't have a driver's licence, so it obviously depends a lot on the place in question. And young people are clearly the ones most likely not to have a driver's licence. Many are waiting even longer before getting one.
You said they can use a student card to vote, but that isn't a realistic option for a lot of young people who don't have proof of residence, which means they can't use their student cards as identification at the polls.
I have more questions for you as well.
