Tremblant can be very very cold. It was gorgeous fresh -5C and 22cm last friday, but it got flattened and frozen on Sat/Sunday when temp dropped to -25C. Definitely bring layers, good gloves and socks.
Lots of flat areas, so either keep your speed up or bring a pole. This mountain is much more skier friendly. Lots of moguls or bumpy areas (again, great for skiers) - can be fun if you like that sort of thing. I had fun in them on Friday, not so much on Saturday when everything for harder and my board got slow from the cold.
Also, LCBO is SAQ in Quebec.
