OK, I'll try to make a good wrap up of the option here.....
Mont-Sainte-Anne
http://www.mont-sainte-anne.com/Mont.../Home/Home.asp
Good place for Ski and snow-board. Nice place to stay right at the bottom as well. About 30 minutes from Quebec City
My place
Le Massif.... AWESOME place for ski and snow-board. LOTS of snow there, not that many place to stay and not that much stuff to do, about 45 to 60 minutes from Quebec City. The view at the top is beautiful and the trails are good.

Le Massif du Sud:
http://www.quebecweb.com/massifdusud...langue=ENGLISH This one is South shore of Quebec City, about 75 minutes from the old Quebec part of town. This is the place to be for challenging trails and snow condition. Not that much to do, but if you are looking for snow, good price and awesome trails in the wood, that's the place to be. It's a remote station compare to the other ones, so it's closed on Monday, Tuesday and Wednesday. If you can make it there on a Thursday..... well powder snow heaven....
Stoneham:
http://www.ski-stoneham.com/Stoneham.../Home/Home.asp Great snowboard accommodation, the snow park is quite big and the Half Pipe is used for a world cup event that takes place there every year, so good stuff

A little on the small side though. 20 minutes from Quebec.
Le Relais:
http://www.skirelais.com/EN/index.php Even smaller than Stonehan, but again grrrrreat snow park.... and cheap. The closest one from Quebec city, around 15 minutes.
Here's a google heart shot with them all.
