Why do people think that happens? It does not happen. 90% of the tariffs will be absorbed by Canadian companies trying to keep up sales to the US because there's nowhere else to go, and even if they sell elsewhere, it'll be discounted that much to other countries because of the general laws of supply and demand.

The only way, and it's one that we have nothing in place to effect, is to mark prices as of the tariff date and to enact an export tariff for the amount of the sale under the price set point. That would highly discourage discounting sales and pretty much just cut them off since, in the case of products made or produced in the US, it would be competing with local products at 125% of the local price.
