U.S. Plunges Trade Pact with Canada and Mexico into Doubt

International Trade attorney Patrick Childress spoke with The Wall Street Journal about the Trump Administration's decision not to renew the United States-Mexico-Canada Agreement (USCMA) and what the move means for businesses across North America. U.S. Trade Representative Jamieson Greer confirmed on July 1, 2026 – the deadline for the three countries to extend the agreement for 16 years – that the United States would not agree to renewal; although the announcement did not come as a surprise, it means trade representatives will now have to convene annually to review and renegotiate the deal. The Trump Administration's demands for a new pact include imposing some tariffs on Mexican and Canadian products instead of applying blanket duty-free treatment, particularly in the automotive sector where it wants to raise the threshold for vehicle material origin requirements. U.S. trade officials are also pushing for provisions requiring higher U.S. content for manufactured goods. Mr. Childress, who previously served as the lead USTR attorney during the initial negotiation and implementation of USMCA in 2020, commented on the progress of talks between the U.S. and Mexico versus the U.S. and Canada, observing that the latter remains in a less advanced stage and warning that gap could spell trouble later.

"The danger for Canada is that the U.S. and Mexico will reach agreement on changes to important provisions of the treaty, and then show up in Ottawa presenting those changes on a take-it or leave-it basis," he said.
