A week before Donald Trump fired off yet another tariff threat on his neighbors, Justin Trudeau and Claudia Sheinbaum had a chance to confer in person about how to tackle that very scenario. Would they join forces against their errant trading partner or was it going to be a case of every person for themselves?

The president-elect said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until Canada, Mexico and China halted the flow of drugs and migrants.

The report also notes that the economic impacts would be even worse in the likelihood that Canada and Mexico retaliate since U.S. manufacturers rely heavily on components shipped from those two counties.
