A top Chrysler official issued a grim threat to Canadian lawmakers, warning the struggling U.S. automaker may shut down its plants in Canada if it doesn't get significant labor concessions and government aid.

"Chrysler LLC cannot afford to manufacture products in a jurisdiction that is uncompetitive, relative to other jurisdictions," president Tom LaSorda told a Parliamentary committee Wednesday night.

Chrysler's labor costs in Canada work out to about $20 an hour more than automakers like Toyota Motor Corp. and Honda Motor Co., LaSorda told the committee.

"Currently Chrysler CAW (Canadian Auto Workers) are not competitive," he said.

The automaker also asked for roughly $2.3 billion dollars from the Canadian and Ontario governments and demanded relief in a tax dispute with Ottawa.

"Failure to satisfactorily resolve these three factors will place our Canadian manufacturing operations at a significant disadvantage relative to our manufacturing operations in North America and may very well impair our ability to continue to produce," LaSorda said.

The company has about 9,000 employees in Canada, where it operates assembly plants in Windsor and Brampton, Ontario, and a casting plant in Toronto.
