Every day more than $4 billion worth of goods cross the United States' borders with Canada and Mexico-U.S. auto parts headed for car factories in northern Mexico, cartons of Mexican avocados bound for California supermarkets, Canadian aluminum destined to become cans of Campbell Soup. Much of this bustling cross-border commerce is duty-free, thanks to the US-Mexico-Canada Agreement, or USMCA, that President Donald Trump negotiated with America's northern and southern neighbors during his first term.
Sales are down nearly 70 percent at Jahn Engineering, a tool and die shop that serves automakers here and in the United States. Dozens of workers have been let go following decisions made in the White House. The Canadian auto industry has been rocked by President Donald Trump's abandonment of subsidies for electric vehicles and embrace of tariffs.
