Oshawa GM plant to cut shifts in the fall, citing U.S. tariffs, union says

General Motors is cutting shifts at its Oshawa Assembly Plant starting this fall due to U.S. tariffs, the union representing workers said.

The plant is moving from a three shift to a two shift operation, according to a news release from Unifor on friday.

"We will not allow GM to barter Canadian jobs to gain Donald Trump's favour," said Unifor National President Lana Payne in a statement.

"Cutting the third shift at Oshawa Assembly is a reckless decision that deals a direct blow to our members and threatens to ripple through the entire auto parts supplier network."

GM's Oshawa plant "will return to a two-shift operation in light of forecasted demand and the evolving trade environment," spokesperson Jennifer Wright said in an email to CBC Toronto on Friday.

"These changes will help support a sustainable manufacturing footprint as GM reorients the Oshawa plant to build more trucks in Canada for Canadian customers," she said.

Wright said the company "will work with our partners to support employees through the transition."
