Le Canada est officiellement en guerre commerciale avec les États-Unis, son plus proche client.
In March 2025, Prime Minister Justin Trudeau officially declared Canada's entry into a trade war with the United States in response to President Donald Trump's imposition of tariffs on Canadian imports. Trudeau criticized Trump's decision as "stupid" and warned of negative consequences for American workers. Provincial premiers, including François Legault of Quebec and Doug Ford of Ontario, announced measures to support affected businesses and retaliate against the U.S., such as financial aid, penalties on American companies bidding for public contracts, and halting business with American entities.
