General Motors (GM) has threatened to shift more production to Mexico and away from a Canadian plant, amid ongoing strikes. 

The Detroit-based automaker has informed Canadian union officials that if workers at the facility in Canada do not stop striking, it will shift more production to a plant in Mexico, the Wall Street Journal reported.

GM told the union representing workers at the sport-utility plant in Ingersoll, Ontario that should workers continue to strike, it would increase production of the Chevrolet Equinox SUV at two of its facilities in Mexico.

"They said they're going to ramp up production at their Mexican operations to satisfy the American and Canadian markets," said Jerry Dias, president of Unifor, which serves Canadian auto workers.

In September over 2,000 workers went on strike at the Canadian plant over disputes regarding expiring contracts. The two sides have yet to resolve the matter.

Shares of General Motors were falling over 1.3% during Thursday morning trading.
