MADD is fairly active in Canada, and they've been influential in getting the legal blood-alcohol level lowered. Most provinces now have penalties (not criminal) if you're over .05 to go with the preexisting criminal penalties for over .08. I think that the penalties for drunk driving are harsher and more enforced than in the past too. And they also have graduated driver's licenses for young people now, which (I think) include zero tolerance or something.

But overall probably more sane to try to stop drunk driving by young people rather than drinking by young people.
