I took part in the 10 week course with ski le gap, I have to say it is without a doubt the best thing I have ever done! Tremeblant by itself is such a amazing place for both skiing and other activities as well as it's night life.
The coaching given by ski le gap is the best I've ever had, throughout my entire stay two level 4 coaches were helping me along the way eventually helping me obtain my level 2 ski instructor qualification. But the most enjoyable part of the skiing is how chilled out the coaches were they never put anyone under pressure they just wanted us to have fun and enjoy ourself a whilst becoming better skiers.
The trips to quebec, ottowa and Montreal were a very nice addition to the course it gave us a chance to see three great cities and experience different cultures within Canada.
If anyone is thinking of doing ski le gap I'd tell them do it 100% as I know they won't regret it.
