President Donald Trump imposes 50% tariffs on most Canadian goods, saying Canada unfairly discriminates against American autos, alcohol and dairy products. The White House says the tariffs are launched under Section 338 of the 1930 Trade Act through multiple presidential proclamations. The administration says the duties would take effect about 30 days later, leaving a window for negotiations. Tariff coverage excludes certain items including energy products, potash, fish and critical minerals, according to reporting. Multiple outlets also say the new 50% tariffs extend to categories that previously received protection under the United States-Mexico-Canada Agreement (USMCA), which the U.S. did not renew and whose renegotiations could extend through 2036.

Canada’s government says it supports free and fair trade and is prepared to negotiate with the Trump administration, while officials warn the move raises costs for families and could worsen bilateral tensions. Canadian political leaders and industry groups call for a negotiated solution. Critics argue using the Great Depression-era authority increases uncertainty and could lead to wider retaliation or broader trade escalation. The disputes cited by the White House are linked to earlier U.S. actions and Canada’s retaliatory measures involving autos and alcohol, as well as the U.S. position on cheese and dairy.
