I'm in Canada, and want to buy the Prime in a physical store. All these release dates are confusing, when can I expect to be able to purchase one?

Just sold my iPad 2 today, and I'm pumped for the Prime. However, I've heard everywhere from Canadian availability being the 5th, the 8th, the 12th, the 19th, etc...I'd like to purchase it in a physical store, such as Future Shop, so when can I expect the Prime to be available?

Thanks guys!
