Canadian negotiators had gone into the talks suggesting the ultimate goal should be to create a “Fortress North America,” as they called it, with ultralow or nonexistent tariffs inside its walls, namely between Canada and the United States, and aligned tariffs for outsiders.The United States wanted Canada to apply U.S. tariffs to other countries, particularly when it came to steel, now and in the future: If the United States changed policy and place higher tariffs on certain goods from a third country, Canada would need to do the same, even if it already had a trade agreement in place, a Canadian official said.
Tariff alignment is one thing. Canada having to change their tariffs because an Italian comedian made a joke about Trump, or whatever, is quite another.
