The union representing Canada’s automotive workers said talks on a new labor deal with Stellantis have stalled over the company’s plans for a factory that has been idle for two years.

The impasse centers on the future of the Ontario facility, which has been out of operation for two years. The union said the company’s plans for the plant remain a key sticking point in negotiations.

Stellantis has not commented on the status of the talks. The union represents workers at the Ontario factory and other Stellantis operations in Canada.

The stalled negotiations come amid broader uncertainty in the North American auto industry as manufacturers shift toward electric vehicles and adjust production capacity. The union has said it is committed to securing a deal that protects jobs and investment in the Ontario plant.

No further details were immediately available on when talks might resume.
