I ski with at Tremblant all the time and speak regularly with the Intrawest guys up there and they have never mentioned anything about this happening. For now I am going to just say its a rumour but I'll try and get some confirmation from their park manager ASAP.
In my opinion I don't think it would happen for the sole reason that their halfpipe is not at a worldclass level. I've been told that they are looking to relocate their halfpipe and get new equipment, but until that happens I don't see X-games coming to Tremblant.
I really hope I'm wrong because that would be so ill. I think they could make a pretty sick slopestyle course for the athletes but we'll have to wait and see!
No man your right it wasnt available in quebec.. but i dont know for the rest of the canada
