What’s going on at General Motors?

General Motors (GM) is planning to cut one of its three shifts at its assembly plant in Oshawa, Ontario in the fall.

The automaker announced on May 2 that it has decided to reduce production at the facility — which makes Chevrolet Silverado trucks — “in light of forecasted demand and the evolving trade environment.”

Jeff Gray, president of the Unifor local at GM’s Oshawa plant, claims the move will not only affect around 700 hourly jobs, but also 1,500 to 2,000 employees at parts suppliers that operate within the facility and at other factories.

The union is calling on Prime Minister Mark Carney and his political counterparts to meet with U.S. President Donald Trump as soon as possible and “fix the [auto] tariffs.”

According to reports, approximately 3,000 people work at GM’s Oshawa plant.

Reaction from Canadian officials

Anita Anand, minister of innovation, science, and industry prior to the recent federal election, posted on X (formerly Twitter) that she’s “profoundly disappointed” by GM’s decision.

“Our government introduced relief for the auto sector on the assumption that manufacturers maintain their production levels in Canada,” Anand’s post reads.

“I want to be clear: the federal government is entitled to revise these previous commitments, should we not see a long-term investment and production plan in Canada.”
