U.S. Trade Representative Jamieson Greer met Canadian officials in Washington on August 17, 2026, as Canada seeks to avert 50% tariffs scheduled for 12:01 a.m. Wednesday on $20 billion of its exports. The 5,525-mile border sees 330,000 daily crossings and $2 billion in goods, with additional context including 800,000 Canadians residing in the U.S. and a petition against U.S. Ambassador Pete Hoekstra that collected nearly 218,000 signatures. Analyses differ on whether the tariffs represent protectionism, reciprocity, or state coercion.
