GM Cuts Third Shift at Oshawa Plant, Hundreds Face Layoffs

General Motors (GM) will eliminate the third shift at its Oshawa Assembly Plant on January 29, 2026, resulting in significant job losses. The decision will directly impact over 700 positions at the facility, along with additional layoffs among suppliers, as the company shifts its focus in production.

Job Losses Amid Strategic Changes

According to Unifor, the union representing workers, many employees will face unemployment due to this decision. GM states that approximately 500 employees will be laid off as part of this restructuring. Lana Payne, national president of Unifor, criticized GM’s choice to cut the shift, suggesting that the company has prioritized external pressures from former President Donald Trump over the needs of its Canadian workforce.

This move follows GM’s announcement in May 2025 to reduce operations at the Oshawa plant, which primarily manufactures Chevrolet Silverado pickup trucks. As part of its strategy, GM has increased Silverado production at its facility in Fort Wayne, Indiana, responding to tariff pressures introduced during Trump’s administration.

Commitment to Oshawa Despite Layoffs

Despite the layoffs, GM has emphasized its ongoing commitment to the Oshawa plant. The company has invested $280 million to prepare for the production of new models of gas-powered full-sized pickups. GM expressed gratitude to its employees for their hard work and contributions, stating that they have worked closely with the union to provide support during this transition.

The decision to cut the third shift underscores the complexities facing automakers as they navigate a rapidly changing market. As GM adapts its operations, the ramifications for the workforce in Oshawa highlight the challenges posed by shifts in production strategies and external economic pressures.
