Honestly, the only way to keep that cost in the US is to mandate that anyone selling across border has a price set as of the day of the tariffs. If they sell under that price, they get export tariffed for the difference. Then at least there's a chance that the tariff burden will be passed on to the US consumers and maybe they'll do something.

But we don't have anything in place to make something like that happen at this point, and even if we did, I doubt we have the political will to shelter Canadians that way. Sure as fuck Polievre won't do any such thing.
