GM Oshawa Layoffs: 1,200 Workers Face Job Cuts - What's Next for Autoworkers? (2026)

A devastating day has arrived for autoworkers in Oshawa, Ontario, as GM Canada prepares to cut a shift at its local plant, resulting in the loss of over a thousand jobs. This news has been dreaded for months, and now the reality is sinking in.

The Impact of GM's Decision

Up to 1,200 workers are expected to work their final shift on Friday, as GM scales back its Canadian operations. Jeff Gray, president of Unifor Local 222, who represents these workers, shared his concerns. He stated, "We did everything we could to make our case to General Motors."

GM's decision to cut the midnight shift, one of three, will impact workers based on their seniority. High-seniority members will be reassigned to the remaining shifts, while those with lower seniority across all shifts will unfortunately lose their jobs.

Gray described the situation as "heartbreaking," as these workers will enter their shifts unaware that it will be their last. He added, "You feel nervous and anxious about providing for yourself and your family."

The Background: Tariffs and Trade

GM's shift cut announcement last year followed U.S. President Donald Trump's imposition of tariffs targeting the auto sector. Jennifer Wright, a GM spokesperson, cited "forecasted demand and the evolving trade environment" as reasons for the decision.

Interestingly, GM is simultaneously adding 250 temporary workers to its plant in Fort Wayne, Indiana. Both the Oshawa and Fort Wayne plants produce the Chevrolet Silverado.

The layoffs, initially scheduled for November, were delayed until the end of January, giving the union more time to lobby the federal government for a trade deal with the U.S. and to try to reverse GM's shift reduction decision.

Unifor's Response and Future Plans

Unifor has been vocal about the impact of these job cuts, initially estimating that around 2,000 workers would be laid off. Gray later clarified that the number has decreased to between 1,100 and 1,200 due to the efforts of in-plant representation.

Gray has called on national union leaders to increase their support, as he believes auto jobs across Ontario are at risk. He stated, "From the perspective of the members, the pushback hasn't been enough."

Unifor plans to advocate for more jobs in Oshawa and is developing programming to retrain laid-off autoworkers. These programs may include resume writing skills and basic computer training, to be hosted at action centers across Ontario.

The Role of CUSMA

GM's layoffs come at a critical time, as Canadian leaders prepare for a mandatory review of the Canada-U.S.-Mexico Agreement (CUSMA). U.S. Trade Representative Jamieson Greer has indicated that CUSMA needs changes before Trump agrees to extend it, citing issues like Canada's dairy quota system, online streaming laws, and ongoing boycotts of U.S. alcohol in some provinces, including Ontario.

Gray hopes that the premiers will encourage the federal government to actively pursue a renewal of CUSMA with the U.S. He believes this could bring things back to normal, stating, "That's the best answer for us - to return to the United States, our most reliable and dependable trading partner for the last 100 years."

As trade talks with the U.S. and Mexico intensify, the future of the auto industry and the livelihoods of thousands of workers hang in the balance.
