The head of Canada's largest private union has issued a warning to General Motors after meeting with Prime Minister Justin Trudeau.
Unifor president Jerry Dias suggests the Canadian and U-S governments could band together to punish G-M if it insists on closing five plants at the end of next year.
Dias represents about 2,500 workers at the factory the carmaker plans to shut at the end of 2019.
After meeting with the Prime Minister Dias said GM has moved production of five models of vehicles to Mexico and the United States in the past few years, and if the Oshawa plant closes, the company will have only one left here.
Dias argues that if General Motors stops making cars in Canada, it would devastate the parts industry and that would cause big trouble for other car companies.
He says labour standards in Mexico are low and Trudeau has to work with President Donald Trump to keep manufacturing jobs from shifting south.
Dias says Prime Minister Justin Trudeau has said he will ``roll up his sleeves'' and talk to General Motors C.E.O. Mary Barra.
