Trump Imposes 50% Tariff on Canadian Goods, Sparking Trade Conflict

New Tariffs Spark Tensions Between US and Canada

US President Donald Trump has taken a new step in the ongoing trade disputes with Canada by signing orders to impose 50 per cent tariffs on various Canadian goods. The move is based on the claim that Ottawa has been treating American products unfairly, particularly in the areas of alcohol, automobiles, and dairy. These tariffs are set to take effect in 30 days and will cover a wide range of items including wine, hockey sticks, and cement.

The White House cited Section 338 of the Tariff Act of 1930 as the legal basis for these new duties. This provision has not been used before, making it an untested approach for the administration. Trump, who has faced several of his tariffs being struck down by the Supreme Court this year, is now relying on this lesser-known legal tool.

Canadian Prime Minister Mark Carney responded to the announcement, stating that Ottawa is prepared to "intensify" discussions with the United States. He mentioned that proposals have been made to address disputes and modernize the US-Mexico-Canada Agreement (USMCA). Carney emphasized that Canada's actions are in response to what he describes as unilateral US trade measures that violate the terms of the agreement.

The latest tariffs do not apply to energy, potash, or goods already under sector-specific tariffs. However, they will affect products covered under the USMCA, raising concerns among some businesses about potential escalations in trade tensions.

Trump has imposed duties on US trading partners since returning to the presidency last year, but these usually exempted goods entering the country under the USMCA. His recent actions could further strain relations with Canada, which is the second-largest trade partner of the United States.

The White House also pointed out that Canada is one of two countries, along with China, that have retaliated against Trump's sweeping duties since 2025. The administration highlighted that most Canadian provinces have stopped purchasing US alcohol due to Trump's tariffs and repeated calls for annexation of Canada as America's "51st state."

US Trade Representative Jamieson Greer accused Canada of taking US alcohol products off shelves, providing better market access to dairy products from the European Union, and imposing caps on US vehicle exports to Canada from companies reshoring to the United States. He stated that the tariff announcement aims to "hold Canada accountable for its retaliation and discrimination."

This move marks the first time that Section 338 has been used to impose tariffs, according to Scott Lincicome of the libertarian Cato Institute. Many experts believe the law has been superseded by other authorities, and Lincicome argues that Trump has "demonstrated a willingness to use and abuse any statute on the books."

Ryan Majerus, a former US trade official, noted that the law is "subject to a lot of litigation risk" and has never been tested. He suggested that the move is likely intended to gain leverage over Canada, especially given that USMCA negotiations are ongoing and talks with Mexico have progressed faster than those with Canada.

"If the tariffs were to take effect as announced, however, Majerus expects that the removal of exemptions for USMCA imports would have substantial effects," he said.

Chris Swonger, president of the Distilled Spirits Council of the United States, expressed appreciation for the acknowledgment of Canada's restrictions but hoped the issue could be resolved without further escalation. He warned that steep tariffs could risk further retaliation, especially at a time when many US hospitality businesses are facing financial hardships.

Lincicome added that Washington's discrimination claims over dairy products could be seen as "dubious" given Canada's trade deal with the European Union. He noted that while it's not guaranteed that a court will strike down the tariffs, it will take some time, creating a period of significant uncertainty.

The situation highlights the complex nature of international trade relations and the potential for further conflict between the US and Canada. As both nations navigate these challenges, the outcome of their negotiations will be closely watched by businesses and policymakers alike.
