If the device was directly shipped from Finland to Canada than yes, there would be an import tax, but if a product is brought into the US, than sold by a US entity to a member of NAFTA than depending on it's category of affiliation it is not subject to export or import tax.

Ex. I'm a company in the US, I buy a product from TokyoFlash ( Japan watch company ), which I then list on my website as a product that I sell, I can ship said product to Canada without any taxes depending on it's category affiliation outlined during the NAFTA negotiations of 1988 and post-signatory amendments.

Although it's frowned upon, this practice of trade has been going on for quite sometime. At the recent G20 summit this particular issue was brought up between the Canada and the US, though in the past Mexico has opposed banning this type of trade because of the amount of monetary influx it receives into their economy ( which desperately needs every single dollar )
