GM Cuts Third Shift at Oshawa Plant, Hundreds Face Layoffs

General Motors (GM) is set to eliminate the third shift at its Oshawa Assembly Plant, effective January 29, 2026. This decision will lead to the loss of hundreds of jobs, with the union representing workers estimating that over 700 direct positions will be affected. In addition, numerous jobs in the supply chain are expected to disappear as a result of this move.

According to GM, approximately 500 employees will be laid off directly. The announcement follows earlier plans made in May 2025 to reduce operations at the Oshawa facility, which primarily manufactures the Chevrolet Silverado pickup trucks. The company has indicated a shift in production focus to its Fort Wayne, Indiana plant, a change that has been attributed in part to evolving tariffs under the administration of former U.S. President Donald Trump.

Lana Payne, the national president of the Unifor union, criticized the decision in a statement, asserting that GM has opted to “cave to Donald Trump rather than stand up for its loyal Canadian workforce.” This remark underscores the tensions surrounding labor relations and the impact of political decisions on local employment.

Despite the layoffs, GM has expressed its ongoing commitment to the Oshawa plant. The company announced an investment of $280 million to prepare for the production of its latest models of gas-powered full-sized pickups. This investment indicates that GM intends to maintain a presence in Oshawa, though the immediate future for many workers appears uncertain.

GM has stated that it is working closely with Unifor to support affected employees through the transition. The company has expressed gratitude for the contributions of its workforce during this challenging period.

As the automotive industry continues to adapt to changing market conditions and political landscapes, the situation at the Oshawa Assembly Plant serves as a poignant reminder of the complexities involved in manufacturing and labor relations in North America.
