Inframe News – Automakers had been hoping recent U.S.-Canada trade talks would bring some relief from the 25% tariffs already affecting vehicles and parts crossing the border. Instead, the situation took a sharp turn after the United States announced plans to raise the tariff to 50% starting January 1.
The proposed increase applies to vehicles, auto parts and trucks imported from Canada. The trade agreement that recently fell apart was expected to reduce the top tariff rate on Canadian cars and light-duty trucks from 25% to 15%. The new 50% rate would put Canadian-built vehicles under a much heavier burden.
Canadian-made vehicles represented around 6% of U.S. vehicle sales in 2025, according to Barclays research. While that share may appear relatively small, several major automakers depend heavily on Canadian factories for models sold across the U.S. market. The higher tariff could therefore affect production costs well beyond vehicles assembled in Canada.
General Motors is among the companies exposed to the change, with about 17% of Chevrolet Silverado production taking place in Canada. The Silverado is GM’s top-selling model in the United States. Stellantis also builds the Chrysler Pacifica exclusively at its Canadian facility, while Ford is preparing to import Super Duty trucks from its Oakville plant.
Toyota and Honda also face significant exposure because of their manufacturing operations in Canada. The two Japanese automakers accounted for more than 75% of Canada’s 1.2 million vehicles produced in 2025, according to the Global Automakers of Canada. Many of those vehicles are shipped south into the United States.
The tariff issue also extends beyond finished vehicles. Canadian and U.S. automotive plants rely on parts moving across the border multiple times during the manufacturing process. A higher tariff on those components could add costs throughout the North American production network.
Automakers have also raised concerns about the different tariff treatment facing North American production. Imports from several Asian and European markets currently face a 15% tariff under separate trade agreements. Canadian and Mexican vehicles, meanwhile, have remained subject to higher rates, with some relief available based on U.S. content.
U.S. officials have also considered requiring vehicles imported from Canada and Mexico to contain at least half U.S.-made parts to qualify for lower tariffs. Similar content requirements do not apply to vehicles imported from Asia and Europe. That difference has added another layer of uncertainty for automakers planning production across North America.
The higher tariffs could also affect future investment decisions. A senior Honda executive said the company may reconsider plans for an eighth North American assembly plant if the United States-Mexico-Canada Agreement is not extended. The warning comes as automakers weigh where to place new factories and production capacity.
Some industry sources still expect the United States and Canada could reach an agreement before the new tariffs take effect in January. The remaining months give both sides time to return to negotiations over vehicle and parts trade. Until then, automakers are facing uncertainty over costs, production locations and cross-border shipments.
