U.S. President Donald Trump has officially informed Canadian Prime Minister Mark Carney that the United States will impose a 35% tariff on Canadian exports, effective August 1. The announcement came via a formal letter sent on Thursday, marking the latest escalation in Trump’s aggressive trade strategy.
This move places Canada among several nations now facing steep tariffs from the U.S., amid a broader shake-up of global trade dynamics led by Trump.
USMCA Under Pressure as Talks Reset
The decision disrupts ongoing negotiations between Canada and the United States, which were originally targeting a resolution by July 21. Both Canada and Mexico are now urgently seeking a compromise to preserve the United States-Mexico-Canada Agreement (USMCA), the trade pact that replaced NAFTA in 2020.
“Throughout the current trade negotiations with the United States, the Canadian government has steadfastly defended our workers and businesses. We will continue to do so as we work towards the revised deadline of August 1,” Carney stated on X (formerly Twitter) Thursday evening.
A Wave of Tariff Letters
Since Monday, July 7, Trump has issued over 20 letters to foreign governments, announcing new tariffs or warning of impending penalties. While Canadian and Mexican exports were initially targeted with 25% tariffs, some energy products from Canada received lower rates or were later exempted under USMCA provisions.
This latest announcement, however, significantly raises the stakes.
Trump’s Broader Strategy and Diplomatic Tensions
Trump has long criticized Canada and Mexico for what he claims is a lack of effort in controlling illegal immigration and drug trafficking across the U.S. border. Yet, despite these tensions, Trump and Carney have managed to maintain a surprisingly cordial relationship. The two met at the White House in May and again during the G7 summit last month in Canada, where world leaders urged Trump to scale back his trade measures.
In a recent gesture of goodwill, Canada agreed to roll back digital service taxes on U.S. tech companies — a move meant to ease strained relations. However, it did little to halt the latest tariff decision.
More Countries May Be Next
In an interview with NBC, Trump revealed that additional blanket tariffs ranging from 15% to 20% may be imposed on other countries starting August 1 — particularly those that haven’t yet received a formal letter. He noted a letter to the European Union, the U.S.’s largest trading partner, would be sent “today or tomorrow.”
In the case of Brazil, Trump threatened tariffs as high as 50% unless new trade agreements are reached. Brazilian President Luiz Inácio Lula da Silva expressed openness to negotiations but emphasized that Brazil may impose reciprocal tariffs if necessary. Trump’s letter also criticized Brazil’s treatment of former President Jair Bolsonaro, a staunch Trump ally.
Global Uncertainty and Trade Risks
The announcement has cast fresh doubt on the future of the USMCA and sparked concern among global trade analysts about a potential new wave of protectionism and economic conflict driven by Washington.
With multiple countries now bracing for tariffs and diplomatic fallout, the next few weeks could prove pivotal in reshaping North America’s trade framework — and beyond.
