I am a third year student at McGill and have had some really sick seasons so far and you will too. Montreal has access to some amazing skiing - but it gets really fucking cold.
So here is the deal at McGill and what you can find:
Jay Peak - located about 15 minutes inside the US border - about 2 hrs (maybe a little more because the roads suck) from McGill. They used to run a bus every Saturday and Sunday from Roddick gates (Sherbrooke + McGill college) for $20 return for the day. It was amazing, butt hey cancelled it last year which sucked a lot. If you can get to Jay I highly recommend it. Hit it on a powder day and you will have the day of your life - deep snow, great trees and absolutely no life lines. It's a completely locals' only mountain. The park really sucks if that's what you are after - two "parks", one with a mini jump line and around 4 rails/boxes, and another with a bigger jump line and stupidly big rails that no-one hits. The parks are fun to fuck around with on the way down, but don't expect to go there for the day and do park laps. It's a sick mountain and they get soo much snow. Bought a season pass for $300...
Last year I made the switch to Tremblant. Season pass is $280 or something. My buddies and I rented a car each week and drove out there - there is a bus, but it takes about 3 hrs (opposed to an easy 1hr 45minute drive in the car from Mtl) and it is super expensive - worth it if you are staying the night up in Tremblant though.
Overall I was hugely disappointed with Tremblant. Touristy, massive lines, WAY overpriced and just a huge commercial resort. It's one of those resorts where you have to pay for a "park pass" - comlete bullshit. They don't really get that much snow, and if they do they just groom it all out because it is basically a beginners' mountain. All the runs are the same - completely groomed and VERY EASY. If you do manage to hit it on a pow day, check out the "edge " lift, has some of the only good tree skiing I found on the mountain - it is a super fun lift and much less crowded.
The parks, on the other hand, are pretty great - definitely a mountain you can hit up to session park all day. Lifts allow you to make fast park laps (besides the massive lines for the lift).
This year I am definitely not hitting up Tremblant - way too boring of a mountain and WAY too expensive.
I recommend joining the Snowboard Club (not just for snowboarding, so many skiers too). YOu pay $100 for membership and then only 25-35$ per week, including bus and lift ticket! no hassle or risk or driving up, and we hit up a different mountain every week - including some in the US including Stowe and Jay, along with all over Quebec.
It's a much better deal and less hassle - you can also bring guests, and they do not pay much at all.
They go every Saturday. Leave very early.
As A.G. mentioned above, you can also join the McGill Freestyle club - a park club that makes trips to Bromont (I think?) in the week?
So yeah, many options for you. If you put the money and time in, you will have a SICK season and few years skiing at McGill.
Also, Mt. Royale is a graet place to go when it snows - my buddies and I occasionally build a kicker or something and go at night - so fun... always get super fucked up and hit jumps.
Or taboozing... always a good time.
