The United States has announced a new round of tariffs on Canadian imports, increasing trade tensions between the two neighboring countries. President Donald Trump introduced the new measures on Monday, saying they are meant to respond to what his administration calls unfair treatment of American products in Canada.
The new policy will place a 50 percent tariff on a wide range of Canadian goods entering the United States. According to the White House, the tariffs are scheduled to take effect in 30 days.
The administration used Section 338 of the Tariff Act of 1930 to impose the new duties. It is the first known use of this law in nearly 100 years. The law allows the president to apply tariffs of up to 50 percent on imports from countries considered to have treated American goods unfairly.
The White House said the tariffs will affect nearly $20 billion worth of Canadian imports. That represents about 5.2 percent of all goods imported from Canada in 2025.
The new tariffs will apply to products including wine, hockey sticks, cement, dairy products, swimming pools, furniture, fishing rods, seeds, clothing, wigs, and several other consumer goods.
Some products are excluded from the new measures. Oil, natural gas, critical minerals, potash, and goods already covered by existing sector-specific tariffs will not face the additional 50 percent duty.
The Trump administration said Canada has imposed policies that limit market access for American products. Officials pointed to restrictions involving U.S. alcohol, automobiles, and dairy products. They also argued that Canada has provided better market access to products from other trading partners while limiting opportunities for American companies.
U.S. Trade Representative Jamieson Greer said the tariffs are intended to hold Canada accountable for what Washington considers discriminatory trade practices. He also said Canada was one of the few countries to respond with retaliatory trade measures after earlier U.S. tariff actions.
The White House also cited the U.S. trade deficit with Canada as another reason for the decision. According to U.S. government figures, the United States recorded a goods trade deficit of $46.4 billion with Canada in 2025. Officials said Canadian oil and natural gas exports account for much of that trade gap.
The latest announcement comes in addition to tariffs already in place on Canadian products. Existing duties include tariffs ranging from 15 percent to 50 percent on steel, aluminum, and copper, along with a 25 percent tariff on certain non-U.S. parts used in imported vehicles.
The administration also said the new tariffs will apply even to products covered by the United States-Mexico-Canada Agreement. White House officials argued that the current trade agreement does not provide enough benefits for the United States in its present form.
Canadian Prime Minister Mark Carney criticized the latest tariffs, calling them another unilateral trade action by Washington. He said the measures violate the commitments made under the North American trade agreement and warned they could increase costs for businesses and families in both countries.
Carney said Canada has already presented several proposals to resolve the dispute and modernize the trade agreement. He added that his government remains ready to continue discussions with the United States in the coming weeks.
Canadian officials also said higher tariffs could disrupt long-standing supply chains and raise prices for consumers. They stressed that continued negotiations remain the best path toward resolving the trade dispute.
The latest tariff announcement marks another step in the ongoing trade conflict between the United States and Canada. Businesses in manufacturing, agriculture, retail, and other industries are expected to monitor developments closely as both governments continue discussions before the new tariffs take effect.
