The Globe and Mail reports in its Saturday edition that as U.S. war plans go, there is nothing secret about the one President Donald Trump has plotted for Canada's auto sector. The Globe's Jason Kirby writes that from his vow to "crush" and "permanently shut down" carmaking in this country to his barrage of tariffs, the signal is clear: There should only be one country on the continent that makes cars for Americans. It is unlikely Mr. Trump will get his way and fully drive vehicle production out of Canada. The President's scheme will do little but push up costs, reduce consumer choice and put domestic automakers at a competitive disadvantage to their international rivals. Still, there is a strong chance that Canada's auto sector will shrink in a trade war. To hear Mr. Trump tell it, snatching auto production away from Canada is as simple as flipping a switch. Canada exports 1.1 million vehicles annually to the United States, accounting for less than 10 per cent of cars and trucks sold south of the border. To fill the gap left by Canada, automakers would need to build six new U.S. plants, according to Toronto-Dominion Bank economists Marc Ercolao and Andrew Foran. Full onshoring could cost U.S. industry $100-billion (U.S.).
