GM Ends Oshawa Third Shift, Cutting About 500 Jobs

Union leaders blame U.S. tariffs for cuts linked to increased truck output in Indiana.

General Motors says it's investing $280 million in its Oshawa assembly plant to produce its next generation of full-sized internal combustion engine pickup trucks. Chevrolet Silverados sit on the General Assembly line at the GM plant in Oshawa, Ontario, on Feb. 22 2022.

Overview

  • The final midnight shift in Oshawa ended at 6:30 a.m. Friday, marking the start of layoffs that follow GM’s return to a two‑shift operation.
  • GM says roughly 500 direct jobs are eliminated, while Unifor and local estimates put total losses, including suppliers, at up to 1,200.
  • Unifor accuses GM of caving to President Donald Trump’s tariff pressure; GM denies a tariff link, citing forecasted demand and a C$280 million investment to build next‑generation gasoline pickups in Oshawa.
  • GM has added about 250 temporary workers at its Fort Wayne, Indiana, truck plant, which builds the Silverado, as some output previously handled in Oshawa’s third shift is absorbed in the U.S.
  • Industry Minister Mélanie Joly called the cuts completely unacceptable, said Ottawa will seek to recover public funds tied to GM investments, and pledged support for affected workers.
