Washington Opens Door to Interim Canada Deal as CUSMA Talks Could Extend Into 2027

Washington is seeking an interim trade arrangement with Canada before the end of 2026, while negotiations over the most complex elements of the Canada–United States–Mexico Agreement could continue well into 2027.

U.S. Trade Representative Jamieson Greer told the Senate Finance Committee that the Trump administration wants to develop interim arrangements with Canada and Mexico and present possible options to the leaders of the three countries by the end of the year.

Greer did not provide details about the legal structure or specific sectors that might be covered by an interim Canada–U.S. agreement. His remarks, however, suggest that Washington may seek preliminary understandings on urgent trade disputes while leaving broader changes to the continental agreement for later negotiations.

The most complicated issues include automotive rules of origin, requirements governing the amount of North American or U.S. content in vehicles, and the enforcement of labour and environmental standards. Greer acknowledged that resolving those matters could require additional negotiations and congressional involvement in 2027.

The proposed interim arrangements could reduce some of the uncertainty facing businesses without completing the full review of the trade agreement, known in Canada as CUSMA and in the United States as USMCA.

President Donald Trump declined on July 1 to approve a new 16-year extension of the agreement in its current form. That decision did not terminate CUSMA, but it triggered a process of annual reviews that may continue until the three countries agree on renewal.

The agreement remains fully in force until 2036 and can be renewed at any time for another 16-year period, according to the Canadian government.

Canada has repeatedly expressed its support for maintaining and renewing the trilateral agreement. Canadian Minister responsible for Canada–U.S. Trade Dominic LeBlanc said CUSMA supports millions of jobs across North America and gives Canadian businesses secure and predictable access to the country’s two largest trading partners.

The United States has also been conducting separate negotiations with Canada and Mexico, raising concerns that the trilateral agreement could gradually be reshaped through bilateral arrangements.

Talks between Washington and Mexico appear to be further advanced, while major disagreements remain between the United States and Canada. Reuters reported that the separate negotiating tracks are testing the three-country structure at the heart of the North American trade pact.

For Canada, an interim agreement could provide temporary relief and greater predictability for businesses affected by trade tensions. Its real value, however, would depend on whether it addresses U.S. tariffs and what concessions Washington demands in return.

The central question is whether an interim arrangement would serve as a bridge toward renewing CUSMA as a unified continental agreement—or mark the beginning of a shift toward separate deals between Washington and its two neighbours.
