No open a Canadian Hot dog stand, For the bun use a rolled up pancake, you'd throw a quarter slab of bacon into it, and douse the thing with maple syrup. Dessert would be Coffee Crisp, and the only pop you could sell would be Canada Dry. And don't accept paper money, only loonies and twoonies.
You also have to have a uniform, I suggest a canuck jersey and toque.
I don't think it would be really tasty but I'd buy one once.
Not sure about the precooked thing, there are a few popcorn stands and lots of roasted chestnuts stands those aren't precooked. I do beleive you need to prove you have access to running water and a washroom, not for your clients but for yourself, usally just an agreement with a neighbouring building.
