US President Donald Trump announced on Tuesday that he will double tariffs on all steel and aluminum imports from Canada, raising them to 50 per cent. The move comes in response to Ontario imposing a 25 per cent tariff on electricity exports to the United States. In a statement on Truth Social, Trump said he has directed the US Commerce Secretary to implement the additional 25 per cent tariff, which will take effect Wednesday morning. "Also, Canada must immediately drop their Anti-American Farmer Tariff of 250% to 390% on various US dairy products, which has long been considered outrageous. I will shortly be declaring a National Emergency on Electricity within the threatened area," Trump wrote. In addition to targeting metals, Trump warned of potential tariff hikes on Canadian automobiles. He stated that if Canada does not remove what he described as "egregious, long-time tariffs," the US will impose substantial increases on car imports starting April 2. The tariff escalation marks another flashpoint in US-Canada trade relations, raising concerns about broader economic consequences for industries reliant on cross-border supply chains.
