I would love to do this, but lodging near slopes tends to be quite expensive - do you stay a bit further away, or have you had success sharing a house with a group of people doing the same thing?
Salt Lake city is quite affordable and im ~45 minutes to Brighton, Park city, Solitude, Snowbird, etc, excluding traffic. But pretend i didn't say that, traffic in the canyons already sucks, and more people will only make it worse.
Montreal? For Snowboarding? No offense, but snowboarding conditions in the western United States and western Canada is so much better than Montreal. For example Mont Treblant only gets 164 inches of snow on an average year[1], while Snowbird, Alta, Brighton and Solitude in Utah average 500 inches a year.
