As the GM strike continues, thousands of Canadian workers have been furloughed. Evidently, the strike that is occurring in U.S. plants is having a negative impact on Canadian facilities. Production at the GM plant in Ontaria, Canada has been fully halted as a result of the strike. Canadian union leaders have stated that Canadian workers support the strike, despite losing work because of it.
