U.S.-built cars fall to 28.4% of Canadian sales, and the steepest drop is at foreign brands' U.S. plants

Vehicles built in the United States made up 28.4% of new-vehicle sales in Canada in the first half of 2026, down from 35.4% a year earlier, according to JD Power Canada data reported by Fortune and Motor Illustrated, citing Automotive News Canada. From 2021 through early 2025, U.S. plants had supplied roughly 40% of Canada's new cars.

The shift follows the 25% U.S. tariff on Canadian-built vehicles introduced in April 2025 and Canada's retaliatory duties on U.S.-made vehicles. Fortune reported the U.S. levy is expected to double on Jan. 1, 2027, and to extend to Canadian auto parts and steel.

Where the cars come from now

Figures from JD Power Canada as reported by Motor Illustrated; the South Korea 2025 figure is derived from its reported one-point gain. JD Power Canada's Robert Karwel said Mexico could challenge the U.S. as Canada's largest vehicle source in 2027 if tariffs stay in place. Canada's own plants did not pick up the slack, losing share to changeovers and lower output.

The thing the headlines get wrong: this is not mainly a Detroit problem

Much of the coverage frames the drop as tariffs backfiring on the Big Three. The breakdown by automaker points somewhere else.

Ford, GM, Stellantis, Honda and Toyota all build cars in Canada and can use Canada's tariff-remission framework when they keep up qualifying production. For those five, U.S.-built vehicles were still 45.2% of their Canadian sales, down just 3.1 points from a year earlier.

The collapse was among automakers with no Canadian assembly plant, such as Subaru and Kia. U.S.-built vehicles fell to 4.9% of their Canadian sales from 17.7%, a drop of almost three-quarters. Subaru has moved essentially all Canadian supply to Japan, Hyundai Canada is drawing more from Mexico and South Korea, and Mazda has stopped importing the CX-50 into Canada, according to Motor Illustrated and The Car Guide. Nissan and BMW have also cut imports from the U.S.

So the export volume being lost is mostly coming out of foreign automakers' American factories, not Detroit's. Those companies had used U.S. plants to serve all of North America. When tariffs make that uneconomic, they can supply Canada from home or from Mexico, which Detroit, with its Canadian plants and the remission framework, has so far had less need to do.

Who it hits

Canada is the largest export market for U.S.-built vehicles, bigger than the next 10 combined, according to an RBC analysis cited by Fortune. Every point of that share is output that U.S. assembly plants, and the parts suppliers and trucking firms that serve them, no longer ship north. For Detroit's own production news this week, see Ford's F-150 pause at Dearborn.

What to watch: whether the U.S. tariff on Canadian vehicles doubles on Jan. 1 as expected, and whether Detroit's own U.S.-built share in Canada, still at 45.2%, starts to fall as fast as everyone else's.
