US to Canada package forwarding service?

Hey Tildes,

There's a product that is sold in US Costco, where the Kirkland brand is a fraction of the price of the Canadian Costco brand name version. Without knowing anything about tarrifs or customs clearing, do you guys know of a service that I can ship to in US, that will forward my package to a Canadian address? Or is that all kinds of illegal or was possible but not anymore? Brief search on Reddit turned up AI and astroturfed results sadly
