The Supreme Court ruled this February that Trump had lacked the legal authority to impose the tariffs by declaring an economic emergency, causing the administration to find alternative ways to raise import taxes based on a series of legal authorities.

Tariffs are taxes on imports, which companies can then pass along to consumers in the form of higher prices. The president maintains that the costs created by tariffs will cause manufacturing to relocate to the U.S., though there is little evidence of that in the economic data.

The latest import taxes could worsen Trump’s weak ratings on the economy. He promised voters when running for the presidency that he would bring prices down, but the annual inflation rate has risen since he became president because the tariffs and the war in Iran are pushing up oil prices.

The Trump administration official said the president had also requested that his aides look into additional tariffs on Canada because its wildfires hurt air quality in the U.S. He had publicly threatened to do so in social media posts.

At the World Cup final on Sunday, Trump watched the game with Canadian Prime Minister Mark Carney, who has openly challenged the U.S. president and has sought to expand Canada’s trade relations with other nations. The Trump administration official said their time together at the game was not a working visit to discuss trade and tariffs.

Trump claims in the proclamations that Canada discriminates against American autos, alcohol and cheese relative to other nations, but his argument rests in large part on retaliatory actions taken by Canada after the U.S. president imposed tariffs on Canada under the pretext that it should do more to stop fentanyl smuggling.

Trump noted in his autos proclamation that Canada maintained, starting in April 2025, a 25% tariff on the imports of U.S. motor vehicles that did not qualify for preferential treatment under the USMCA.

The White House said regarding alcohol that all but two Canadian provinces and territories halted the purchase and retailing of American alcoholic beverages beginning last year, which was also a response to Trump’s tariffs and taunts of making Canada the 51st state.

But Trump has long objected to Canada’s treatment of U.S. cheese, saying in his proclamation that Canada discriminates against the U.S. compared to Europe on dairy products.

Trump and Carney have had a frosty relationship, with Carney, a former central banker, who pledged to stand up for Canada during his election campaign last year.

At the World Economic Forum in Davos, Switzerland, in January, Carney called out Trump — without naming him — by saying that the “most powerful” countries are using the economy to coerce less powerful nations.

Trump responded at the time by saying: “Canada lives because of the United States.”
