Truck manufacturer Paccar is ceasing production of U.S.-bound vehicles at its plant in Sainte-Thérèse, Que., according to Unifor.

Daniel Cloutier, the union’s Quebec director, told The Globe and Mail that Paccar will move production of its Kenworth and Peterbilt truck models to the U.S. The decision marks the third blow to Canada’s auto industry in recent days.

On Tuesday, General Motors announced that it will no longer produce BrightDrop electric parcel-delivery vans, which were made at a facility in Ingersoll, Ont. GM said it will stop producing the BrightDrop entirely but pledged to make another vehicle at the Ingersoll facility, which has been closed for retooling. Last week, Stellantis served notice that it is moving production of its Compass Jeep to the U.S. from Brampton, Ont., to Illinois.

Paccar’s move comes as U.S. President Donald Trump is preparing to invoke a 25% tariff on trucks in November and means that the plant will not produce at full capacity.

Cloutier told the Globe that Bellevue, Wash.-based Paccar informed the plant’s employees of the decision on Wednesday. The facility will lose 300 of its 800 jobs; however, some trucks intended for sale in Canada will still be produced there.

“We were building 96 trucks a day and we’re going to get down to 16 or 18,” said Cloutier told the Globe.

Unifor represents the plant’s employees. The union plans to hold talks with the federal and Quebec governments on ways for the facility to produce more Canadian-made vehicles intended for sale in Canada.
