Amplid doesn't ship directly, they use Shop-A-Tron, which is like a system that connects local and online shops into one place. Basically what happens is you order it through shop-a-tron on the Amplid website, they then check the stock of all their dealers and the product gets shipped from them (the dealer), the reason they do this is so that they can ship it from the closest location to you so it should get to you faster. That being said, it depends on the product and shops carry that product whether or not it can be shipped to Canada, to find out if it can be shipped you have to add it to your cart and check-out. However, I did find this on their website:
"We will not falsify invoices or shipping labels under any circumstances. If your country is not an option in the checkout process, we cannot ship to your country. Check a product's shipping notes while you shop to learn of any possible shipping restrictions for particular products."
Which means, when your checking out and you don't see Canada as an option then you can't order it through them and have it delivered to Canada. However, you may be able to find them on a different online shop that will ship to Canada (not all dealers and shops are connected to shop-a-tron).
