Mexico's and Canada's trade ministries delivered letters to the United States Trade Representative on June 1 supporting a sixteen-year extension of USMCA. The move resets the calendar toward the joint July 1 review in Washington, with internal consultations now closed.

According to [El Financiero](https://www.elfinanciero.com.mx/economia/2026/06/03/revision-del-t-mec-mexico-y-canada-piden-a-eu-que-el-acuerdo-se-extienda-16-anos/), Secretary Marcelo Ebrard signed the letter addressed to Jamieson Greer, stating the intention that the treaty be extended through the mechanism built into the agreement itself. Dominic LeBlanc, Canada's Minister of Intergovernmental Affairs, sent a parallel message: the agreement has been a decisive factor in strengthening North American economic integration. Trilateral trade reached $1.9 trillion in 2026, a 32% increase since the treaty entered into force.

The process remains asymmetric as Washington defines its position. Under the Article 34.7 pathway, the USTR must send its own letter by July 1, at which point the Free Trade Commission will convene to decide whether the treaty is maintained, adjusted, or extended for another sixteen years. Mexico's Secretariat of Economy will incorporate the results of national public consultations, open since September, into the country's negotiating position, according to the [official notice published in the DOF](https://www.gob.mx/se/prensa/consultas-publicas-para-la-revision-del-tratado-entre-mexico-estados-unidos-y-canada-t-mec). The submissions cover rules of origin, agriculture, energy, and fair competition conditions.

Analyst Jorge Molina, cited by El Financiero, noted that the U.S. administration has raised concerns over bilateral trade deficits for several consecutive quarters. The USTR's July 1 letter will determine whether the U.S. position points toward a direct extension or toward renegotiation of sensitive chapters.

For Mexico, the signal is one of both pressure and opportunity. A successful extension would consolidate the investment horizon for nearshoring if Washington responds symmetrically, while a U.S. demand for additional concessions would open a window for realignment. The next negotiating round begins this week and runs through June 18 in Washington, with rules of origin, agriculture, and energy on the agenda.
