Trump imposes 50% tariffs on Canadian goods, citing disputes over autos, alcohol and cheese

President Donald Trump on Monday imposed 50% tariffs on most Canadian goods, declaring that Canada has unfairly discriminated against American autos, alcohol and dairy products. Trump signed three proclamations to launch the tariffs under Section 338 of the 1930 Trade Act. The Supreme Court ruled this February that Trump had lacked the legal authority to impose the tariffs by declaring an economic emergency, causing the administration to find alternative ways to raise import taxes based on a series of legal authorities. "If these tariffs proceed, Canada should respond tariff for tariff, dollar for dollar," Ontario Premier Doug Ford posted on social media. Scott Lincicome, vice president of general economics at the Cato Institute, said: "We crossed the Rubicon. The invocation of 338 is the nuclear option for Trump tariffs." Candace Laing, CEO of the Canadian Chamber of Commerce, called the moves regrettable but urged using the 30-day window to make meaningful progress in advancing formal talks.
