USPS is the only way to go for shipments up north.
As a Canadian who sometimes shops online, I would agree with that from the customer's perspective. Packages are handled much more securely by our local post office than they are by the courier services. I've abandoned more than one shopping cart because shipping options did not include the postal service.
