Hello fellow Canadian! (From Edmonton here). There is a Alberta version of clubgp, but it's not too active that I'm aware of.
As for parts, your kinda out of luck I've found, I've ordered all my parts from either grandprixstore.com, or zzp. You do get killed by the shipping and the customs.
Sorry for the bad news, but Welcome Aboard!
