An Uproar in the U.S.-Canada Trade Spat

Written By: Naija Agarwal

On October 25th, 2025, President Trump announced a 10% increase in tariffs on Canada in response to an anti-tariff advertisement that aired in Ontario during the World Series. The anti-tariff ad featured a statement from the U.S. President Ronald Reagan in 1987 on tariffs, where he noted that tariffs on foreign goods contribute to trade wars and job losses, and cost $75 million to broadcast in the United States. Following the advertisement’s release, Trump announced an end to  trade negotiations with Canada, prompting Ontario Premier Doug Ford to take down the advertisement. 

This trade conflict between the U.S. and Canada initially began on March 4th, 2025, though the Trump administration did initially announce a plan to impose tariffs on February 4th, 2025. This initial tariff imposed a 25% duty on most imports from Canada, excluding oil and energy products, which received a 10% tariff. 

Across several months, reciprocal tariffs between Canada and the U.S. have fluctuated, applying to imports of auto, copper, and other materials and products. Trade between Canada and the U.S. accounts for a large percentage of both respective economies. In 2024, the total value of goods and services trade was approximately $909.1 billion, leaving both countries, especially Canada, highly vulnerable to the impact of trade disruptions, limiting the scope for introducing and maintaining retaliatory tariffs. 

As a result of the trade war, Canada is now initiating partnerships with Mexico and China, major U.S. trade partners. In September, Canadian Prime Minister Mark Carney and Mexican President Claudia Sheinbaum met to discuss a partnership that would boost trade and increase competitiveness in the North American market. Carney has also accepted an invitation to visit Chinese President Xi Jinping to increase Canada’s non-U.S. exports and develop closer trading ties with Asia, which would decrease Canada’s dependence on U.S. trade.
