Sainte-Thérèse, Quebec

PACCAR announced 300 additional layoffs at its Sainte-Thérèse, Quebec plant due to heavy-duty truck tariffs imposed by the Trump administration. This follows previous layoffs in December 2024 and July 2025, prompting Unifor to call for a domestic procurement plan to save the facility.

Paccar, a truck manufacturer operating a plant in Sainte-Thérèse, Quebec, is laying off at least 175 workers effective August 4, 2025. The layoffs are attributed to decreased demand for trucks due to economic uncertainty from U.S. tariffs and follow 250 job losses in December 2024.
