General Motors Corp. Chairman and CEO Rick Wagoner says the company plans to close four pickup truck and sport utility vehicle factories in Canada, Mexico, Ohio and Wisconsin.

The company says it will cease production at a full-size pickup factory in Oshawa, Ontario. It also will stop making SUVs at factories in Moraine, Ohio, and Janesville, Wis., and it will stop making mid-size pickups in Toluca, Mexico.

Wagoner announced the moves in response to slumping sales of pickups and SUVs brought on by high oil prices. He says a market shift to smaller vehicles is permanent.

He also says the company will build a new small car in Lordstown, Ohio, in mid-2010. And it will add shifts at car plants in Lordstown and Orion Township, Mich.
