US slaps 50% tariffs on $20 billion in Canadian goods as trade talks collapse

The US imposed 50% tariffs — taxes on imports — on roughly $20 billion of Canadian goods after negotiations collapsed on August 21, 2026. Trump had paused the levies three days earlier, claiming a deal was near. US Trade Representative Greer said Canada backtracked on accepted terms; Carney called last-minute US changes "unfair, uneconomic."
