A friend told me that Super Arzon would be a good place to buy a shisha in Toronto which is how I found it. They have a bunch of them along with a lot of other Iranian groceries in their store. I'd reccomend the Lavaash bread which I believe is baked in house. It's as big as a doormat and I think impossible to carry without folding and tastes excellent. They also have a little restaurant but seating is cramped and right next to a freezer. The food is about the same price as Altona Kebab next door which I'd reccomend over Arzon. The person who owns Altona used to work at Arzon and then went ahead and opened his own place next door. There's another, almost identical supermarket in the same plaza called Pars Bakery which unfortunately closes at about 10 whereas Arzon is open 24 hours (except the restaurant which closes at 4)
