US Canada Tariffs Hit 50%: Negotiations Collapse | Trade War

The United States and Canada failed to reach a trade agreement on Friday, prompting Washington to impose 50 percent import tariffs on roughly $20 billion worth of Canadian goods, including wine, wooden hockey sticks and cement. The US Canada tariffs took effect just after midnight Saturday, marking a sharp escalation in the North American trade war and pushing relations between the longtime allies to a new low.

What led to the US Canada tariff breakdown?

Three days of negotiations in Washington between Canadian Trade Minister Dominic LeBlanc and US Trade Representative Jamieson Greer ended without a deal. Canada then recalled its negotiators to Ottawa. Prime Minister Mark Carney said last-minute changes to US terms were unfair, uneconomic, and called into question the reliability of any deal. Carney vowed Canada would retaliate dollar for dollar.

US officials blamed Canada for the collapse. Greer called the outcome a missed opportunity, saying Canada declined to finalize terms agreed earlier this week. He described the US offer as a historic economic and national security partnership. The failure was a surprise: just two days earlier, both sides appeared close to an agreement, similar to the 2025 Canada US trade war that had been temporarily paused.

How the 50 percent tariffs work

The new duties apply to about 5 percent of Canada's annual exports to the United States, roughly $20 billion in goods. They come on top of existing US tariffs on steel, lumber and automobiles. President Donald Trump invoked Section 338 of the Tariff Act of 1930, a rarely used law that allows tariffs up to 50 percent on countries deemed to discriminate against US businesses. Legal experts say the Section 338 tariff authority has never been used in modern times and will likely face court challenges.

Which Canadian goods are affected?

• Wooden ice hockey sticks
• Wine and other beverages
• Cement and construction materials
• Nearly 500 product categories in total

Energy, fish and critical minerals were exempted, limiting broad consumer impact. Still, the move deepens uncertainty for manufacturers and could complicate the USMCA renewal negotiations scheduled in the coming years.

Background: Canada-US trade tensions

Canada and the United States exchanged $880 billion in goods and services last year. Canada is the second-largest US trading partner and its largest supplier of steel and aluminum. More than 70 percent of Canadian exports go to the United States, and the countries share deeply integrated energy and automotive markets.

The Section 338 statute dates to 1930 and had never been used before this week. Trump's decision to invoke it marks a significant departure from modern trade practice, and legal scholars say the move may violate World Trade Organization rules.

Impact and what comes next

No additional talks are scheduled, and Canada has suspended trade negotiations indefinitely. Economists warn that a prolonged tariff war could raise consumer prices and disrupt integrated supply chains. The dispute also carries political weight, as Carney faces domestic pressure to stand firm while Trump uses tariffs to push for what he calls fairer trade terms.

The tariffs target nearly 500 items but spare energy, critical minerals and fish, which limits immediate consumer pain. However, the larger concern is the trade war itself: Canada has already signaled it will match the duties, and the standoff could spill into future talks over the United States-Mexico-Canada Agreement (USMCA).
