USMCA Review Is Coming in 2026 — Here's What's Actually at Stake for American Workers and Businesses

The USMCA Review and What's at Stake

The United States-Mexico-Canada Agreement — which replaced NAFTA in July 2020 — includes a formal Joint Review clause requiring all three countries to evaluate the agreement in 2026, six years after it took effect. This is baked into the treaty text.

The review does not automatically terminate the agreement. It gives each party the opportunity to extend it, renegotiate terms, or signal intent to withdraw. The agreement's full sunset provision kicks in at the 16-year mark — 2036 — unless renewed.

What the Trump Administration Has Done

Since returning to office in January 2025, the Trump administration applied 25% tariffs on most Canadian and Mexican goods starting in early 2025, citing fentanyl and border security concerns. Those tariffs operate on a separate legal track from the treaty review.

President Trump signed USMCA in 2020 and has since described it as a good deal, while also suggesting it could be improved. U.S. Trade Representative Jamieson Greer has indicated the administration intends to use the 2026 review to push for stronger rules of origin on automobiles, tighter labor enforcement provisions, and new terms addressing Chinese manufacturing investment in Mexico — specifically the concern that Chinese companies are building plants in Mexico to backdoor goods into the U.S. market at USMCA-preferential rates.

That last point reflects a real structural gap in the current agreement that critics across party lines have identified.

What Mexico and Canada Are Saying

Mexican President Claudia Sheinbaum, who took office in October 2024, has said Mexico wants to preserve the agreement but will push back on what she calls U.S. unilateralism on tariffs.

Canada's government, now under Prime Minister Mark Carney following Justin Trudeau's resignation, has similarly expressed interest in maintaining USMCA while objecting to the existing tariff regime.

Both countries have strong economic incentives to keep the deal intact. Canada and Mexico together account for roughly 35% of total U.S. trade, according to U.S. Census Bureau data. Dismantling the agreement entirely would be enormously disruptive to all three economies.

The Tariff Problem

Critics of the Trump tariff approach — including several Republican senators from agricultural states — argue that the 25% tariffs already imposed are functionally undermining USMCA before the review even happens. If the U.S. is already treating Canada and Mexico as adversaries rather than treaty partners, it makes constructive renegotiation harder and risks triggering retaliatory measures that hurt American farmers and manufacturers.

Canada retaliated against the 2025 tariffs with counter-tariffs on specific U.S. goods. American soybean and pork producers in Iowa, Illinois, and Missouri have raised alarms through their industry associations about lost Canadian market access.

What the Debate Is Missing

Most center-left outlets frame the USMCA review primarily as Trump recklessly threatening a stable agreement. Most right-leaning outlets frame it as Trump defending American workers from bad trade terms.

Both framings skip the actual substance. The Chinese manufacturing-in-Mexico loophole is a genuine problem that deserves serious attention. The labor enforcement provisions Mexico agreed to in 2020 have had uneven implementation. And the automotive rules of origin debates have real implications for American factory jobs in Michigan, Ohio, and Kentucky.

The review is a tool. Whether the Trump administration uses it as a scalpel or a sledgehammer will determine whether this ends up being good policy or an expensive trade disruption.

Who This Affects

If you work in auto manufacturing, agriculture, or any industry with supply chains that cross the U.S.-Canada or U.S.-Mexico border, this review affects your paycheck. The outcome is not yet determined. It depends on negotiations still underway.

Watch what the administration formally proposes in review sessions — not the press conference rhetoric. That's where the real story will emerge.
