Canada just walked away from the negotiating table. Prime Minister Mark Carney announced on August 21 that he was suspending bilateral trade talks with the United States and ordering Canadian negotiators back to Ottawa, after what he described as last-minute changes to US demands that were unfair and unreliable.

The retaliation didn’t stop there. Canada pledged to match every US tariff dollar for dollar, a direct counterpunch to Washington’s threat of a 50% levy on roughly $28 billion worth of Canadian imports set to take effect at midnight.

Three days of hope, then a cliff

The collapse came with whiplash-inducing speed. President Trump had paused tariffs around August 18-19, creating a three-day window that was supposed to give both sides room to finalize what appeared to be a tentative deal.

Instead, the US used the breathing room to ratchet up pressure, threatening the 50% tariff that effectively blew up the talks.
