Firstly - Not to slag the local scene, or your ski plans (I too snow-board or two-plank at 'Blue') ...But Blue Mountain Ain't even a mountain, more of a large hill. FYI Blue Mountain is in Southern Ontario, about 1 & 3/4 hours from Toronto proper. It's at the edge of South-Western Georgian Bay. Its a nice little condominium strewn winter playground for those who want to partake in snow sports, but can't get out to Quebec, British Columbia (Whistler Black Comb) or Stateside for the weekend.
As for the Bryston dealers etc., you'll find that greenbacks are very popular anywhere in Canada – But you'll find better audio deals in Western Canada. There's a real protectionist mentality in THIS country. Too bad the government’s selling the people out anyway - and cheaply I might add.
...At any rate you might find a deal, but its not going to be that great because you'll have to find a way around the GST. You could pay here and have it shipped state-side, but the dealer will have already paid Goods and Services Tax (to Bryston) and won't be willing to do the paperwork to recoup it - you'd have to chase the CDN Govt. for it (that's 7% bro!) So... looking closer to home might be better. I purchase most of my stuff when I'm in Ohio - whether local sales or not.
Good luck,
Mike
