look into cat riding. you get to access heli-esque terrain, you get more runs in, and its cheaper.
chugach powder guides in AK - i think SnoWolf used them...among many others, as well as operators in the lower 48 (mt bailey)
otherwise for resorts: Jackson Hole, Revelstoke, Shames, etc. will offer the type of riding you're looking for. as for POW well sometimes you just gotta get lucky with the weather. go in march.
i dunno what riding in quebec is like but no way in hell would i go to vt to look for powder.
