Well, since this is "World" Photography Forums, I'll chip in with my 2 cents (Canadian) with the two stores I buy most of my gear from in Toronto:
1. Aden Camera -
www.adencamera.com
2. Downtown Camera -
www.downtowncamera.com
Of course, the big franchise here is Henry's (
www.henrys.com), but I find the prices a bit on the high side.
cheers,
