(Reuters) -Unifor members at the CAMI Assembly and Battery Assembly plants in Ontario have ratified a two-year contract with General Motors that achieves significant pay increases, the Canadian labor union said on Sunday.

Unifor Local 88 members voted 95.7% in favour to ratify the contract which will see workers' pay rise 10% immediately with a 2% increase in September 2025 and an additional 3% increase in July 2026.

The contract will also provide for a 20.25% wage increase for skilled trades, the union said in a statement.

The new two-year agreement is now set to expire on September 20, 2026, according to Unifor.

"For the first time Unifor has successfully negotiated a two-year contract term that will align CAMI members with the union's Detroit Three negotiations to combine the future bargaining power of more than 5,600 GM members," Unifor National President Lana Payne said.

GM did not immediately respond to a Reuters request to comment.

Unifor Local 88 represents more than 1,300 members at the CAMI Assembly and Battery Assembly which manufacture the Chevrolet BrightDrop EV 600 and EV 400 and Ultium battery modules.
