Unifor has reached tentative agreements with General Motors covering more than 4,600 workers at five Ontario facilities.
The deals apply to members at Oshawa Assembly Plant, CAMI Assembly Plant in Ingersoll, St. Catharines Propulsion Plant and Woodstock Parts Distribution Centre. Talks began August 10 after Unifor ratified a pattern agreement with Ford Motor Company.
The union said bargaining took place during tariff uncertainty and ongoing U.S. trade pressure.
Unifor represents 320,000 private‑sector workers across Canada.
“Our bargaining committee worked diligently to reach these agreements, which deliver strong income and benefit gains, amid some of the most challenging times in our history,” said Unifor national president Lana Payne.
Unifor said the GM agreements secure the pattern set with Ford.
“We entered this round of talks in the midst of tariff uncertainty and relentless U.S. trade aggression,” said Unifor GM master bargaining chairperson Trevor Longpre. “Thanks to the hard work of every member of our negotiating team, we emerged with a deal that secures the pattern set by our union with Ford.”
Ratification meetings are scheduled for August 29‑30.
