Go to amazon.com rather than amazon.ca. You can use your existing Amazon account, US Prime is separate from Canadian Prime. We got our groceries delivered to bell services, although some people report meeting the delivery driver (I think you have to if there's alcohol being delivered). Lots of good info in the Grocery Delivery FAQ thread over on the Resorts board
