A big (and stupid) bone that gets many American online people (and their Canadian quisling brethern) very excited is the "high tariff" on agricultural goods. People whip out the above-quota tariff rate and say "look at what they are charging!" without understanding what a tariff-rate quota is.....
Trump posts threat he will increase autos and auto parts tariffs on Canada to 50% on Jan. 1st. The industry is highly integrated across the border.
