GM Cuts Oshawa Shifts Amid U.S.-Canada Tariff Dispute

General Motors will reduce operations at its Oshawa Assembly Plant in Ontario from three shifts to two starting this fall, a move expected to affect about 700 jobs. The decision comes after U.S. President Donald Trump imposed a 25% tariff on Canadian-built vehicles, prompting reciprocal tariffs from Canada and creating uncertainty in cross-border trade. GM said the change is intended to maintain a sustainable manufacturing footprint as it focuses on building more trucks for the Canadian market. Unifor, the union representing Oshawa workers, condemned the shift cut as reckless and urged GM to reverse its decision. Ontario Premier Doug Ford expressed concern for affected workers and their families. U.S. Customs recently exempted certain auto parts compliant with the Canada-U.S.-Mexico Agreement from tariffs, and further developments are expected as trade discussions continue.
