50% Tariffs Signed
The tariffs are set to take effect in 30 days, and the White House said they will apply even to goods previously protected from import taxes under the USMCA, while excluding energy products, potash, fish, critical minerals, and products already subject to national-security tariffs such as steel and aluminum.
NPR reported the administration previewed the action by saying Canada is one of the only nations other than China that retaliated against Trump’s previous tariffs and must be held accountable, and it said Trump signed three proclamations under Section 338 of the 1930 Trade Act.
In a statement, Canadian Prime Minister Mark Carney said, “Canada stands ready to engage intensively to address outstanding issues with the US to the mutual benefit of our citizens,” as the BBC described the decision as a “tough choice” for Ottawa to fight back or hold firm.
The BBC also said the levies will come into force on 19 August, linking the timing to on-again talks to renew the North American free trade agreement with Mexico known as the USMCA.
Officials, Industry, and Law
A senior administration official told reporters the tariffs are meant to “hold” Canada “accountable” for “substantial retaliation against the United States,” and the official pointed to provinces halting the purchase, distribution, or retailing of U.S. alcoholic beverages while not imposing similar restrictions on other countries.
The White House also framed the action as leveling the playing field for “motor vehicles, alcohol, and dairy,” while ABC News reported the president signed three proclamations under Section 338 imposing “additional 50% tariffs on certain goods of Canada in response to these discriminatory measures.”
ABC NewsScott Lincicome of the Cato Institute said the invocation of 338 is “the nuclear option for Trump tariffs,” and NPR quoted him saying, “We crossed the Rubicon.”
The Guardian reported that several Democratic lawmakers proposed repealing Section 338 because they said Trump could use it to destabilize the economy, and it said Trump signed three proclamations to launch the tariffs under Section 338 of the 1930 Trade Act.
In a statement carried by El Mundo, Jamieson Greer said, “TCanada has removed American alcoholic beverages from Canadian shelves (…) and imposed a cap on U.S.-made vehicle exports to Canada,” as the dispute escalated into a new round of tariffs.
What’s at Risk Next
The BBC said pollster David Coletto, CEO of Abacus Data, described “deep anger” among many Canadians over what they view as unfair treatment from the US, adding that “most people do not want Mark Carney to cave.”
Ontario Premier Doug Ford posted on social media that, “If these tariffs proceed, Canada should respond tariff for tariff, dollar for dollar,” while Candace Laing, CEO of the Canadian Chamber of Commerce, said the two countries need to use the 30-day window before the tariffs start “to make meaningful progress in advancing formal talks.”
Time Magazine reported that the Office of the U.S. Trade Representatives said Trump’s proclamations cover nearly $20 billion in imports from Canada, or about 5.2% of the almost $382 billion worth of goods the U.S. imported from Canada in 2025, and it said the refusal to renew the USMCA has mired trade ties in further uncertainty.
The Guardian added that Trump had threatened last week to impose tariffs due to smoke from wildfires in Canada drifting across large portions of the US, and it quoted Trump writing on Truth Social, “We are holding Canada responsible for the fact that they are not properly maintaining their Forests, and Brush therein.”
