That's basically what US companies were doing with Chinese stuff when those tariffs were announced but not in force yet (and maybe earlier if they got early wind about it).
Dunno what's going on with NAFTA/CUSMA/USMCA. Changes with the wind. Or maybe you'll qualify for duty-free under our supposed trade agreement if you pay some assessor mafia $9999 to confirm that your handmade good is Made in Canada.
I also sell something that has a max value people would be willing to pay, so if that number is $6, then I'd rather get $6 USD than $6 CAD.
