I always order my film (35mm and 120) and chemicals from B&H. They always have everything I'm after, and the price is right, even after shipping fees to remote Fogo Island, off of Newfoundland's northeast coast. I simply can't afford to shop Canadian when it comes to film and darkroom supplies.
Living in Mississauga and needing 120 B&W film quickly just prior to traveling, I went to Henrys in Mississauga and cleaned them out of 120 TMY and FP+4, which was 4 and 3 rolls respectively.
They indicated they could order, but that was what they had on hand.
A little more lead time would have been the smarter solution.
