The walkout by workers came after Canadian union Unifor said GM was "stubbornly refusing" to match the contract the labor union reached with Ford Motor (F.N), which offered wage increases of up to 25% in Canada.
The walkout adds to the headache faced by the automaker in the U.S. where it is racking up millions of dollars in losses per week due to the United Auto Workers (UAW) strike that started Sept. 15.
GM has lost 34,176 vehicles of production since the start of the UAW strike, according to an estimate by Deutsche Bank.
GM has laid off 2,300 U.S. workers due to the impacts of the UAW strike.
At the Oshawa plant, workers build Chevrolet Silverado trucks, one of GM's most profitable models, while the plant's stamping operations supply various parts for GM North America.
