The tariffs could unleash a new wave of economic chaos, with risks of higher inflation and further fraying of relations between two nations that previously had warm, close ties before Trump's return to the White House. The administration official previewing the action Monday said Canada was one of the only nations other than China that retaliated against Trump's previous tariffs and must be held accountable. The U.S. did not renew the U.S.-Mexico-Canada Agreement The new 50% tariffs would exclude energy products, potash, fish and critical minerals, but would include goods previously protected from import taxes by the United States-Mexico-Canada Agreement, or USMCA. That 2020 trade pact was not renewed by the U.S., triggering a new set of negotiations that could run until 2036. Carney said he planned to meet virtually with the country's premiers later in the day Tuesday. British Columbia Premier David Eby was blunt in his criticism of Trump and the proposed tariffs.
