In a major trade move, U.S. President Donald Trump has announced that a 35% tariff will be imposed on all Canadian imports beginning August 1, 2025. The announcement was made Thursday through an official letter addressed to Canadian Prime Minister Mark Carney, marking a significant escalation in already tense trade relations between the two countries.
Trump stated that the decision is a response to ongoing trade imbalances and warned that this tariff will be separate from sectoral tariffs, making it a broad-based measure covering multiple industries. In his letter, he emphasized that the action was triggered during ongoing talks on reciprocal tariffs, where the U.S. has repeatedly expressed concern about Canada’s allegedly one-sided trade practices.
“If Canada increases its tariffs on American goods, we will increase ours. Whatever excess rate you add will be included in our 35% rate,” Trump warned in the letter.
The U.S. President pointed to Canada’s steep tariffs on American dairy products, reportedly as high as 400%, as a major point of contention. He also highlighted concerns over fentanyl trafficking, claiming that substances manufactured or transported through Canada are contributing to America’s opioid crisis.
According to Trump, the growing trade deficit with Canada poses a threat to both U.S. economic strength and national security. He added that the decision is in line with his broader economic vision of “America First,” which aims to reduce dependency on foreign imports and strengthen domestic industries.
The announcement follows a series of aggressive tariff measures taken by Trump earlier this week, including new tariffs on Japan and South Korea, and a 50% tariff on copper imports. These moves reflect a hardening of his stance on foreign trade as his administration pursues protectionist policies ahead of the 2026 midterm elections.
Trade relations between the U.S. and Canada have been fragile in recent years. This latest tariff decision could potentially spark a full-fledged trade war, further straining diplomatic ties and impacting industries on both sides of the border.
As of now, Canada has not formally responded to the tariff announcement, but analysts predict retaliatory measures are likely.
