US puts huge new taxes on $20 billion of Canadian products after trade talks fail

The US slapped a 50% tax on about $20 billion worth of Canadian products after trade talks fell apart on August 21, 2026. Trump had paused the taxes three days earlier, saying a deal was close. US official Greer said Canada backed out of agreed terms; Canada's Carney called last-minute US changes "unfair, uneconomic."
