Summary

Stellantis temporarily laid off 900 U.S. workers at five Midwest plants due to production pauses at Canadian and Mexican assembly sites, prompted by new tariffs.

Plants in Windsor, Ontario (4,500 workers) and Toluca, Mexico (2,400 workers) will close for up to a month.

Stellantis warned of further impacts, citing market uncertainty.

The United Auto Workers union criticized the layoffs as unnecessary, despite supporting the tariff policy. Canadian union Unifor also condemned the move, warning of immediate harm from tariffs before they officially take effect.
