The ban amounts to barely a ripple in $880 billion worth of annual two-way trade between the two northern neighbors. But it marks another ratcheting up of President Donald Trump’s second-term trade war with America’s longtime ally and trading partner.
The import ban “certainly won't do anything to help the trade tensions between the United States and Canada,'' said trade attorney Patrick Childress, a partner at Holland & Knight and a former U.S. trade official.
Economic impact likely to be modest
The economic impact is likely to be minimal. Childress noted that the products on the banned list were already facing Trump’s tariffs. ”For a lot of these goods, the 50% was already acting as a de facto ban by making importation from Canada into the United States uneconomical,″ he said.
Jacob Jensen, director of trade policy at the center-right American Action Forum think tank, calculates that the ban would cover $967 million worth of Canadian imports, based on 2025 numbers. Of that, 87% would be alcoholic beverages that the U.S. targeted because of some Canadian provinces responding to Trump’s provocations by banning U.S. booze from store shelves.
Also banned are some dairy products — including the milk byproduct whey. The two countries have long clashed over Canada’s attempts to protect its dairy industry from foreign competition by imposing hefty tariffs once dairy imports have exceeded a quota.
Longtime ally Canada moves rapidly to find new trading partners
Trump has directed most of his ire at Canada. He is openly seeking to pull Canadian manufacturing south. And he has inflamed public opinion in Canada by repeatedly suggesting that the country become America’s 51st state.
Canadian Prime Minister Mark Carney has sought to reduce Canada’s reliance on the United States, which last year accounted for more than 70% of Canadian exports.
Carney has embraced the prospect of Canada becoming the European Union's first associate member.
Carney also broke with the U.S. earlier this year, striking a deal with China to allow a limited number of Chinese electric vehicles into Canada at a sharply reduced tariff in exchange for China lowering tariffs on Canadian canola.
