The biggest single consequence from Donald Trump’s trade war against Canada so far is unfolding in Brampton, Ontario. A vehicle assembly plant there, owned by Stellantis, is up for sale by the company, which shifted (at Trump’s behest) production of a future new model from Brampton to Illinois. Stellantis wants to sell the plant to Roshel, a company that makes low-volume military vehicles, and has made no commitments to production or employment levels, or to hiring any of the existing staff at the plant.
