TORONTO, Oct 12 (Reuters) - The government of Ontario urged General Motors Co and striking Canadian union workers on Thursday to immediately resolve a month-long strike at GM's plant after the U.S. automaker threatened to move all production to Mexico.
Contract talks stalled over job security and led to the longest strike in 25 years at the factory, known as CAMI, which makes the popular Equinox sport utility.
The issue is escalating just as Canadian Prime Minister Justin Trudeau discusses the North American Free Trade Deal with U.S. and Mexican leaders.
"I feel like we're engaged in a poker game, but the interests of Ontario are sitting on the table right now," Ontario Economic Development Minister Brad Duguid told Reuters.
"It's an uncomfortable place to be, obviously, and we'd really like to urge the parties to find a resolution to this as quickly as possible before permanent damage is done."
Some 2,500 workers at a factory in Ingersoll, Ontario, walked off the job on Sept. 18 after GM rejected the Unifor labor union's call for the automaker to designate the factory as the lead production site for the Equinox in North America.
On Wednesday, GM warned Unifor leaders that it would start winding down production at the CAMI plant unless workers called off their strike.
GM officials told the union that it would ramp up Equinox output at two plants in Mexico if the walkout continued, Unifor President Jerry Dias told Reuters.
The strike is also affecting the plant's supply chain, said Duguid, who is aware of about 1,000 workers in other plants who have been temporarily laid off pending the outcome of the dispute.
Shares in GM were down 1.7 percent on Thursday morning, as the Wall Street Journal reported that the company plans to temporarily close its Detroit-Hamtramck assembly plant.
GM has invested $800 million to retool the CAMI plant and is projected to build about 210,000 vehicles in 2018, according to AutoForecast Solutions, a forecasting firm. The two GM Mexico plants are together projected to build 149,000 vehicles next year.
The Equinox was the second best-selling model in the United States Chevrolet lineup in September, and GM had just 41 days worth of the vehicle in stock at the end of last month, according to Automotive News. (Reporting by Susan Taylor; Editing by Denny Thomas and Susan Thomas)
