Can't tell what the cost is on Alufoil - but I know that Chocalat-chocolat in Montreal carries coloured foil.

I currently have been ordering 6"x7" foil sheets from Alufoil however with our weak Canadian dollar as well as fees and duties to ship cross border I am trying to find a supplier in Canada to order from. Does anyone know of one up here. Everything I see online is about 3-5 times the price of alufoil so in that case it still makes sense to pay those border fees.
