Jamieson Greer Proposes Interim Trade Deals for Canada and Mexico

United States Trade Representative Jamieson Greer testified during a Senate finance hearing on July 22, 2026, stating his intention to provide interim trade renewal options to President Donald Trump, Canada, and Mexico by the end of the year. This move follows Greer's early July announcement that the U.S. would not renew the Canada-U.S.-Mexico Agreement (CUSMA), a decision that triggered rolling reviews potentially lasting a decade.

While Canada and Mexico seek a 16-year extension of the pact, President Trump has dismissed the agreement as irrelevant. The administration has intensified pressure by threatening 50 percent tariffs on various Canadian goods within 30 days. These threats stem from disputes over Canadian supply-managed dairy systems, vehicle quotas, and provincial bans on U.S. liquor.

The hearing revealed a partisan divide in the U.S. Senate. Democratic senators questioned the decision to target Canada over China and noted that rhetoric regarding annexation has deterred Canadian tourism. Conversely, Republican Senator Marsha Blackburn supported the administration's pressure, specifically calling for the restoration of U.S. alcohol sales in Canada.
