I live in Montréal. And yes, we hate you. We hate everyone. Mange d'la marde, grosse pute.
I've been just about everywhere in Canada though. Vancouver and Winnipeg are the best after Montréal, when it comes to big cities.

On the more serious side though, nobody is friendlier than anyone else, at least where I've been. You'll actually find that kinda stuff in smaller, out of the way towns.
