I grew up in Canada and in the 70's and 80's when I ordered something from the US or elsewhere, it would be shipped to me and I would get a notice in the mail that a package was waiting for me along with the amount of taxes that I owed. That's a nice way to handle it because I could order from anywhere in the world and every small vendor across the planet didn't need to understand Canadian tax codes. I suspect if all those companies had to collect and remit taxes to the Canadian government, they would have just refused to ship there. That's the part that would sadden me.
