Yeah I go, am graduating this year.
First year I got a season pass to Jay Peak, but that's because there was a bus there. Second year, got a tremblant pass because had a friend drive.
Last 2 years have been a member of the SSMU Ski and Snowboard club. In my opinion your best bet. Different mountain every weekend depend on the best conditions around, get on the bus and pass out. crazy cheap ski lift tickets and they throw good parties too. I'd recommend that.
Personally, if I had a car, i'd have a Jay pass - by far the best skiing around. Great east coast pow skiing. Its about 1 hr 45 mins away. Or, get a Bromont night pass - $99 for the season for nights (45 mins away).
Enjoy McGil and Montreal , it's a great city with great skiing options.
