Toyota and Honda are emerging as the automakers potentially most exposed to the latest escalation in U.S.-Canada trade tensions. President Donald Trump has threatened to impose a 50% tariff on Canadian automobiles and automotive parts from January 1, 2027, raising the prospect of significant disruption for manufacturers that rely heavily on Canadian production to supply the U.S. market.

The issue extends beyond the two Japanese companies. The North American automotive industry operates through deeply integrated production networks spanning the United States, Canada and Mexico, meaning substantial tariff increases could affect manufacturers, suppliers, workers and ultimately vehicle prices across the region.

Toyota and Honda Carry Outsized Canadian Production Exposure

Toyota and Honda have a particularly large footprint in Canada’s automotive manufacturing sector. Their Canadian operations accounted for more than 75% of vehicles assembled in the country in 2025, according to the Pacific Manufacturing Association of Canada, which the two companies established in April. Honda’s Alliston facility has annual production capacity of approximately 390,000 vehicles, while Toyota operates three production lines in Ontario producing models including the Corolla, RAV4 and Lexus vehicles.

That concentration makes the companies more exposed than automakers with smaller Canadian manufacturing operations. Reuters reported that Canadian-built vehicles represented approximately 17% of Toyota’s U.S. sales and nearly one-quarter of Honda’s U.S. sales in the previous year. A 50% tariff could therefore create a difficult combination of higher landed costs, production reallocations and potential pressure on vehicle pricing.

Tariffs Could Reshape North American Production Decisions

The potential tariffs arrive as Toyota and Honda have made substantial long-term investments in Canadian manufacturing. Toyota has invested more than $12 billion in Canada and began production of the latest-generation RAV4 at its Woodstock facility earlier this year. Honda, meanwhile, has maintained Canadian manufacturing for decades as part of its strategy of producing vehicles close to their principal markets.

Moving production to U.S. facilities could reduce tariff exposure over time, but such adjustments would require significant capital expenditure, supplier restructuring and additional manufacturing capacity. The process is therefore unlikely to provide an immediate solution if tariffs take effect as currently proposed.

Trade Uncertainty Raises Broader Industry Risks

The tariff dispute also introduces uncertainty for suppliers and other manufacturers operating within the North American production ecosystem. Canada has indicated that retaliatory measures could follow, while negotiations over the future of the USMCA remain a central factor for corporate planning.

For Israeli investors, the developments are relevant because Toyota and Honda are major global companies with extensive international supply chains and exposure to North American consumer demand. Currency movements, trade policy, vehicle pricing and global risk appetite could all influence the companies’ earnings outlook and valuation dynamics.

Outlook: The key variable for the automotive sector will be whether Washington and Ottawa reach an agreement before the proposed January 2027 tariff deadline. A negotiated reduction in tariffs could preserve existing production structures and limit cost pressures, while prolonged uncertainty could encourage manufacturers to accelerate investment in U.S. facilities and diversify supply chains. For Toyota and Honda, the challenge will be balancing the efficiency of their established Canadian operations against the rising strategic value of producing closer to U.S. consumers. Until greater clarity emerges, trade-policy uncertainty, potential retaliation, production costs and currency volatility are likely to remain important downside risks for the sector.
