TORONTO -- General Motors of Canada was forced to idle two plants in Ontario on Monday, affecting about 6,000 workers, after employees at one of its suppliers went on strike, a GM spokeswoman said.
The country's biggest automaker scrapped the second shifts at the two Oshawa plants, which make models such as the Chevrolet Impala and Pontiac Grand Prix, due to a parts shortage after TDS Automotive workers walked off the job.
The supplier makes just-in-time deliveries of subassembly components for steering columns, among others parts.
"We're hopeful that TDS and their union will be able to reach a settlement quickly," said GM spokeswoman Pam McLaughlin. "We have a lot of confidence in the collective bargaining process.... We're hopeful it'll turn around.
McLaughlin declined to speculate on how long the plant idling might last, saying: "It really hinges on the supplier and the union's ability to reach a settlement."
Neither TDS nor union officials could immediately be reached for comment.
McLaughlin said GM's third shift was still scheduled at Oshawa Plant 1, which makes the Chevrolet Impala and Monte Carlo models. Oshawa Plant 2, where the Buick Regal and Grand Prix are made, only has two shifts.
