If ever you come to Quebec:
Tremblant, nice azz moutain, but commercial and busy.
Mont Ste. Anne's, beautiful mountain and less commercial then Tremblant.
Grey Rocks and Le Massif are very nice to, but more fun for Skiers.
Aside from the ones mentioned the other Mountains are kinda small, but fun none the less. The St. Sauveur region is full of smaller 20-45 run mountains, great for families and a lot of them have sweet parks if you like that.
Never been to the Eastern Townships much, but supposedly Mont Sutton is supposed to have nice glades.
