North America’s auto industry is entering a high-stakes USMCA fight, and the biggest question is no longer whether vehicles should be built in the region. It is how much of each vehicle Washington wants built in the United States.
The United States-Mexico-Canada Agreement has been central to North American vehicle production since it replaced NAFTA and entered into force in 2020. Automakers have spent years building supply chains around rules that allow cars, trucks, parts, batteries, and components to move across borders with favorable tariff treatment.
Those rules could now change in a major way. Reuters has reported that the U.S. negotiating position calls for raising North American vehicle content requirements to 82%, while also requiring at least 50% of a vehicle’s value to come from the United States.
That proposal is not final USMCA text. It is a reported negotiating demand. But it has already created concern in Canada because it would make U.S. content the real prize inside a trade agreement that was designed around three deeply connected economies.
The U.S. Wants Tougher Auto Content Rules
Under the current USMCA rules, passenger vehicles and light trucks generally need 75% regional value content to qualify for preferential tariff treatment. The agreement also includes labor value rules that require a portion of vehicle value to come from higher-wage North American production.
The reported U.S. proposal would go further. It would raise the regional content threshold to 82% and add a U.S.-specific requirement that at least half of a vehicle’s value come directly from American production.
That would be a major shift. Current rules encourage automakers to source and assemble more within North America. The new proposal would pressure them to place more of that work specifically in the United States.
For automakers, that kind of change matters because vehicle programs are planned years ahead. Engines, transmissions, body structures, electronics, batteries, software modules, and EV components are often sourced through networks that cross borders several times before a finished vehicle reaches a dealer.
Canada’s EV Tariff Move Added To The Tension
The trade tension did not begin with the content proposal. Canada’s move on Chinese electric vehicles has also become a flashpoint.
The Council on Foreign Relations has described Canada’s new arrangement as allowing 49,000 Chinese EVs into the country this year at a 6.1% tariff rate. That decision drew U.S. attention because Washington has treated Chinese EVs, batteries, software, and supply chains as strategic concerns.
The timing makes the issue more sensitive. The USMCA review is unfolding while the U.S. is trying to limit China’s role in North American vehicle production and push more manufacturing back onto American soil.
The first formal U.S.-Mexico rounds also raised Canadian concerns. The United States and Mexico began bilateral talks while Canada was not part of those discussions. Reuters has reported that some industry officials worry Washington could try to reach a framework with Mexico first, then present Canada with a much narrower path later.
Canada Could Lose Influence In The Supply Chain
The most sensitive part of the reported proposal is how it treats Canadian content. Reuters reported that the U.S. demand did not include a clear provision for counting Canadian parts content toward the new U.S.-specific requirement.
That could reduce the strategic value of Canadian factories inside future North American production plans. If automakers need to hit a 50% U.S. value threshold, they may have stronger incentives to shift future sourcing, component production, or assembly work into the United States.
That would not be a simple adjustment. Canada’s auto industry is tied deeply into the regional system, from parts suppliers and assembly plants to battery investments and cross-border component flows.
A vehicle may use parts from multiple plants in multiple countries before final assembly. Changing how those parts count under USMCA could affect where automakers place future investment, which suppliers win contracts, and which plants are seen as safest for long-term model programs.
Tariffs Are Adding More Pressure
The U.S. administration has also criticized the level of vehicle and auto-parts production in Canada while continuing to push for more manufacturing to return to American soil.
Tariffs have made the review feel less like a routine update and more like a pressure campaign. Reuters has reported that the current dispute includes 25% duties on Canadian and Mexican vehicles and components, along with 50% duties on steel, aluminum, and copper from those countries.
For automakers, the biggest problem is uncertainty. Companies need long planning cycles for factories, battery plants, supplier contracts, tooling, future model programs, and worker training.
If the rules change sharply, investment decisions could move quickly. That would affect major automakers, but it would also hit smaller suppliers whose business depends on predictable cross-border production.
The 2026 Review Could Shape The Next Decade
The next U.S.-Mexico round is scheduled for June 16 and 17 in Washington, D.C., followed by another round in Mexico City during the week of July 20. Canada has re-engaged with U.S. officials, but the U.S.-Mexico track has moved faster so far.
The key date is July 1, 2026. Under USMCA’s six-year review process, the three governments must decide whether to extend the agreement for another 16 years.
That date does not automatically end the agreement. If all three countries confirm the extension, the deal can continue with more long-term certainty. If they do not, USMCA enters annual reviews, and the agreement could remain under pressure until 2036.
That kind of uncertainty is exactly what automakers and suppliers dislike. The North American auto industry depends on long investment cycles, stable rules, and confidence that parts and vehicles can keep moving across borders.
The stakes are bigger than one trade formula. The result could influence where future gasoline vehicles, hybrids, EVs, batteries, electronics, and major components are built across North America.
For Canada, the danger is clear. If U.S. content becomes the central test, Canadian plants and suppliers may have to fight harder to prove their place inside a regional system they helped build.
