- Lead. The Trump administration has refused to extend USMCA beyond its 2036 expiry date, choosing instead a framework of annual renegotiations that leaves the $2 trillion North American trade relationship in permanent uncertainty.
- Fact. USTR Jamieson Greer announced the decision on July 1, citing unresolved US trade deficits with both Mexico and Canada and the agreement’s “shortcomings.”
- Stake. While USMCA formally remains in force until 2036, any of the three parties may now exit with six months’ notice — transforming a once-settled trade architecture into an annually renegotiated arrangement.
The United States-Mexico-Canada Agreement, which governs roughly $2 trillion in annual cross-border trade, entered a new phase of instability on July 1, 2026, when US Trade Representative Jamieson Greer formally notified Mexico City and Ottawa that Washington would not extend the agreement beyond its built-in 2036 sunset date.
The fork in the road
USMCA’s text contained a joint-review clause with a precise deadline: by July 1, 2026, the three parties had to choose between a 16-year extension to 2042 or an annual review cycle. The United States chose the second option. Greer’s statement framed the decision as a negotiating posture rather than a rupture: “The United States will continue to engage with Mexico and Canada to address the agreement’s shortcomings and our trade deficits with these countries.”
The practical effect is that the treaty stays alive but becomes permanently provisional. Each annual review can produce modifications — or threats of withdrawal. A country may exit with six months’ notice, meaning that any single review cycle could, in theory, dissolve the agreement before the 2036 date. This contrasts with the settled decade-long framework that businesses on both sides of the borders had priced into supply-chain decisions. The decision builds on tensions already documented when USMCA’s first joint review opened earlier this year amid the highest North American tariff pressure in decades.
What Canada and Mexico face
Canada enters the annual review cycle with an explicit list of priorities: relief from US tariffs on steel, aluminium, automobiles, and softwood lumber, all of which remain in force and have suppressed bilateral trade volumes. Ottawa had hoped that committing to the 2042 extension would produce at least a partial rollback of those levies; that leverage is now largely gone. Mexico faces a different exposure: its export-assembly industry, which supplies the US automobile and electronics sectors, was built around USMCA’s rules-of-origin certainty. Annual reviews introduce a regulatory horizon that makes long-term investment decisions harder to justify.
The EU-US trade deal that entered into force on July 1 — eliminating US tariffs on European industrial goods — adds a competitive dimension: European manufacturers now face lower US barriers than their Mexican and Canadian counterparts do in some categories, complicating the North American preference structure that USMCA was designed to maintain.
The year ahead
The first annual review under the new framework is expected to open in early 2027. Greer has indicated the US will press for tighter labour standards enforcement in Mexico, further restrictions on Chinese-owned manufacturing inside the USMCA zone, and an agreement that reduces the US bilateral deficits. Mexico’s government has said it will seek tariff relief as the primary condition for any further commitments. Canada has asked for the auto-sector provisions to be grandfathered from review.
No date has been set for the first annual review session. The announcement comes as USMCA’s dispute settlement panels continue to hear cases on dairy, solar panels, and aluminium — proceedings that will now run in parallel with a renegotiation process whose scope and calendar remain undefined.
