Donald Trump posted that Canada had been ripping off the United States and threatened new tariffs on cars and trucks, with tariffs on an array of Canadian products affecting roughly 5 percent of exports taking effect over the weekend. Canada plans retaliation in early September while Carney toured a Quebec shipyard with the provincial premier.
