# Proposed Auto Tariffs Could Harm US Automakers

A recent threat by United States President Donald Trump to impose a 50 percent tariff on Canadian autos and auto parts, set to begin January 1, is expected to significantly impact the North American automotive sector, including operations that support the Aiken County economy. While primarily targeting Canadian production, industry experts suggest these tariffs could also inflict substantial pain on US automakers.

The latest tariff threat follows a breakdown in trade negotiations between the US and Canada last week, which led to 50 percent tariffs on $28 billion worth of Canadian goods taking effect on Saturday. In response, the Canadian government announced on Tuesday that it would impose $27.6 billion worth of counter-tariffs starting September 8.

Peter Frise, an automotive and mechanical engineering professor at the University of Windsor, described the proposed scheme as unworkable and self-damaging. He noted that even with a four-month lead time, it would not be feasible for US automakers to relocate all Canadian-made parts production south of the border. Major manufacturers like Ford Motor Co., General Motors Co., and Stellantis NV all maintain production facilities in Canada.

Frise estimated that moving Canadian production to the US would require years and billions of dollars in investment, potentially resulting in thousands of job losses in the interim. He highlighted a severe shortage of skilled tradespeople in the US, including tool and die makers, electricians, millwrights, mechanics, and machinists, which would make absorbing the production challenging.

Andreas Schotter, an international business professor at Western University’s Ivey Business School, echoed these concerns. He stated that the US could not quickly replace Canadian auto-parts production, and a 50 percent tariff would likely disrupt North American vehicle production rather than facilitate an orderly reshoring. Schotter emphasized that automotive components demand precise engineering, validated suppliers, and synchronized production, a process that typically spans quarters or years, not weeks.

While the US may have some domestic capacity and companies could use inventories to manage initial disruptions, Schotter warned that production interruptions could occur quickly for specific vehicle platforms and components if importing Canadian parts becomes economically unviable or if suppliers reduce output. He cited Ford, which produces engines in Windsor for Super Duty trucks, a line supported by approximately 20,000 workers in US plants. Components for many vehicles frequently cross the US, Canadian, and Mexican borders multiple times before final assembly.

Stephen Veldhuis, a professor in McMaster University’s mechanical engineering department and director of the McMaster Manufacturing Research Institute, added that a 50 percent tariff would significantly increase vehicle prices, putting American automakers at a disadvantage against foreign competitors. He noted that popular models like Toyota Motor Corporation’s RAV4 and Honda Motor Co., Ltd.’s CR-V are manufactured in Canada, and Canadian components are used in many popular US-assembled models. Veldhuis concluded that such tariffs could effectively destroy the North American automotive market.
