(0:00 - 0:41) Trade tensions between Canada and the U.S. escalated again today as President Donald Trump announced a 50% tariff on Canadian steel and aluminum, effective tomorrow morning. The move doubles the existing 25% rate and responds to Ontario Premier Doug Ford's Monday decision to impose a 25% surcharge on electricity exports to Michigan, Minnesota, and New York, impacting 1.5 million U.S. homes. Trump, posting on Truth Social today, labelled Canada one of the highest tariffing nations anywhere in the world and demanded it drop what he called 250-390% tariffs on U.S. dairy products. (0:42 - 1:22) He also threatened to raise car tariffs on April 2nd, warning it could permanently shut down Canada's auto industry, which employs over 125,000 workers, according to the Canadian Vehicle Manufacturers Association. Trump's dairy tariff claim draws from Canada's supply management system, where tariffs on imports exceeding quotas can hit 298.5% for butter or 245.5% for cheddar cheese, per Canadian tariff schedules. However, the 390% figure lacks clear backing, with most dairy tariffs topping out below 300%, suggesting an exaggeration. (1:22 - 2:03) Canada's overall average tariff is 4.1% per the World Trade Organization, far lower than protectionist nations, though its dairy protections rank among the world's steepest. Trump also revived his pitch for Canada to become America's 51st state, arguing it would erase tariffs and border issues, claiming the U.S. subsidizes Canada's security by $200 billion annually, a number unverified by independent data. Ontario's Ford countered on MSNBC, branding Trump's tariffs an unprovoked attack and pledging a relentless response, hinting at a potential full electricity cutoff. (2:04 - 2:31) Incoming Prime Minister Mark Carney, in his Sunday victory speech, rejected annexation, stating Canada will never be part of America. The U.S. relies heavily on Canada, importing 60% of its aluminum and more steel than from any other nation, according to the U.S. International Trade Commission. These tariffs will likely drive up costs for American consumers on goods like appliances and vehicles, with small businesses already bracing for supply chain disruptions.
