THen you could also picket and protest on the value of your canadian currency versus the market shre of the US dollar.... yes i know its one to one right now but still contact your government for concessions or drastic changes to your currency. Just cause apple is an american company doesnt mean their stores present in canada still have to pay costs relative to the canadian government etc.
