Canadian Prime Minister Mark Carney said a proposed U.S.-Canada trade deal would have disadvantaged Canada’s auto industry and effectively reduced Canadian businesses to subsidiaries of U.S. companies. He said negotiations accumulated serious disputes over French-language issues, future trade restrictions and the competitiveness of key industries before diverging near the end. President Donald Trump defended his tariffs, saying they had revived and saved the U.S. automobile business. U.S. Trade Representative Jamieson Greer called Washington’s proposal Canada’s best deal, while Commerce Secretary Howard Lutnick accused Carney of seeking political advantage and disputed Canada’s account of the negotiations. Carney said the talks could converge again and cited Monday’s three Liberal by-election victories as support for his government’s approach.
