The Globe and Mail reports in its Thursday edition that trade talks between Canadian and U.S. officials have resumed in Washington, as provincial unity crumbles under harsh tariffs on autos, steel, aluminum and lumber. The Globe's Robert Fife writes that Privy Council Clerk Michael Sabia was in Washington last week for trade talks with Canadian Ambassador Kirsten Hillman, U.S. Commerce Secretary Howard Lutnick and U.S. Trade Representative Jamieson Greer. Ottawa is focused on lifting U.S. sectoral tariffs justified by President Donald Trump under Section 232 of trade law. When the talks paused for the weekend, Prime Minister Mark Carney said his negotiating team was seeking tariff relief for key Canadian sectors. Stellantis said Tuesday it is moving a production line from its Brampton, Ont., plant to the United States, marking another setback for the Canadian economy. The move appeared to respond to Mr. Trump's protectionist trade policy aimed at bringing carmaking back to the U.S. On the same day, U.S. tariffs on softwood lumber increased to 45 per cent. The premiers, who previously stood united with Ottawa, have begun to criticize the Prime Minister's trade strategy as provincial economic priorities become apparent.
