More and more people are saying this.
NGL these are some pretty astounding stats, especially considering how car-brained most of Canada is. Even so, our transit usage (in major cities) completely eclipses the yanks (I have not independently verified these stats but the user seems knowledgeable enough that I did not bother).
Taken from a 
thread from /r/fuckcars on the topic of obesity rates between different states/provinces (the consensus was that while there are other factors at play such as diet, car-dependency seems to be the overall defining factor for obesity rates).

something something pOPuLaTiOn DEnSiTy like there aren't a shitload of rail and lightrail lines through the Alps and Himalayas where no one lives.
Like all our population centres are basically on a straightish line, mostly with no mountains.
You could drop a single high-speed rail line from Edmonton to Halifax and connect half the country's population within 12 hours of each other with no problem. I'm not sure how high speed a rail you could cook up between Vancouver and Calgary but the rest should be an obvious project.
It's actually way easier (and cheaper) than that. Half the country's population lives in a straight fucking line between Windsor and Quebec City.
