President Donald Trump signed three proclamations on Monday imposing 50% tariffs on a range of Canadian goods — wine, dairy, cement, furniture and even ice-hockey gear — though energy, potash and critical minerals were spared. To do it he reached for Section 338 of the Tariff Act of 1930, an obscure Depression-era statute that lets a president punish nations deemed to discriminate against American commerce. The duties, covering some $20bn of trade, take effect in thirty days.
The White House argues Canada has long tilted the playing field, pointing to Canadian levies on American cars, milk and drink. Ottawa sees it differently: Prime Minister Mark Carney called the move a breach of the USMCA free-trade pact, yet pointedly declined to retaliate, offering instead to “engage intensively” in talks. Provincial premiers were fierier, demanding a response “dollar for dollar”. Economists warn that tariffs ultimately fall on consumers, stoking inflation on both sides of the border.
