General Motors shares fell Monday after President Trump announced 50% tariffs on Canadian vehicle and part imports. The policy becomes effective January 1, 2027.
The announcement followed the collapse of trade negotiations between the two nations over the weekend. Trump issued the update via social media.
GM stock dropped approximately 2% during the session. Competitors Ford and Stellantis recorded larger declines of 4%.
The tariffs create significant uncertainty for automakers using integrated cross-border supply chains. Investors expressed concern over future manufacturing costs and profitability for Detroit’s major automakers.
