Welcome from the southwest corner of the country.
I'm curious who you source materials from.
Somehow i have amassed a very large stock of films, papers and chemicals that i am picking away at. We were pretty lucky in Whitehorse to have a good family owned photo store that would order anything we needed if they didn't stock it. They shut down about five years ago, so mail order is the only option.
I have started using "The Camera Store" out of Calgary and Beau Photo Supplies in Vancouver have also been good to deal with on the phone. For the longest time i would order from a lab i use to work at in Ottawa (Ginn Photo) and they would ship it across the country, but no more, they also closed down a few years ago.
There is always the Vistek and Henry's but i like the small shop with personal service kind of experience.
Recently i found again KHB Photografix in Welland, Ontario. I used them in the pass and had lost their contact, they do repairs, lots of darkroom supplies and large format stuff.
For hard to source weird stuff there is always Freestyle Photography for us on the West coast but with the exchange...
