INGERSOLL, Ontario - General Motors Co said on Monday that it would invest C$90 million ($85.1 million) to expand a joint venture plant in Canada where it builds the Chevrolet Equinox and GMC Terrain crossovers.

GM also said it would recall about 150 workers to the CAMI Automotive plant in Ingersoll, Canada, a joint venture with Suzuki Motor that has about 2,000 hourly workers.

The automaker said it was beginning work immediately to retool the plant to increase production by 40,000 vehicles per year for the North American market. The work will take about seven months. The plant now produces 185,000 vehicles annually.

GM recently started a third shift at the 20-year-old plant and recalled about 300 workers. With Monday's announcement, no remaining CAMI workers will be on layoff, the automaker said.

Workers at the plant are represented by the Canadian Auto Workers union. GM Canada has about 9,000 employees. ($1=1.057 Canadian dollar) (Reporting by John McCrank; Writing by David Bailey; Editing by Lisa Von Ahn)
