On August 21, 2026, Prime Minister Carney announced he was suspending trade negotiations with the United States. In his official published statement Carney said:

In recent weeks, we made important progress toward improving Canada's position as having the best deal in the world with the U.S.

However, last-minute changes in the U.S. proposed terms were unfair, uneconomic, and called into question the reliability of any deal.

At midnight tonight, the U.S. intends to impose a 50% tariff on roughly $28 billion of Canadian goods. Canada will match those tariffs dollar for dollar to protect our workers and businesses. In the coming days, the government will introduce additional measures to support Canadian workers and businesses, building on the nearly $25 billion in support provided over the past 18 months.

At 6:38 am Trump posted the following on Truth Social:

Canada has been ripping off the United States of America for years. Their ridiculously high tariffs on our Farmers and farm products has made life impossible for these great American Patriots, and has long created a 60 Billion Dollar Deficit between our two Countries. Not sustainable, and NOT ANYMORE! On January First, 2027, Tariffs on all Cars, Trucks, both large and small, Automotive Parts, and Steel, will be increased to 50%. Build in the U.S. and there are ZERO TARIFFS. Canada will be treated like a State no longer! On Trade, and in other ways, also, they are among the worst Nations in the World to deal with. They feel entitled, and yet, WE DON'T NEED CANADA, THEY NEED US! They do 95% of their business with the U.S., with us, the exact opposite! Thank you for your attention to this matter! President DONALD J. TRUMP

At 11:03 am Trump posted the following on Truth Social:

Lots of "bluster" from Doug Ford, who is the Premier of the Canadian Province of Ontario, but who is better known as the less charismatic, intelligent, and overall unimpressive brother of the late, great, Rob Ford. America has been carrying Canada for decades, but no longer! The U.S.A. will always be far bigger, richer, and stronger than Canada. Without the United States, Canada couldn't survive — It's where they get all of their money and, because of their current bad leadership, primarily Governor Carney, and his Flunky, Ford, they will not be allowed to keep taking advantage of the United States — Their key to survival. Remember, much of the Electricity, Oil, and Gas that Canada gets is transported through the U.S.A. Someone should get these clowns to "fall in line" or, the consequences for Canada will be far WORSE! Canada's Unemployment Rate is now at 10%, and rapidly rising. Their businesses are fleeing for the United States, and it's all because of their failed policies, and inept leadership! The days of ripping off our Farmers, and other Businesses, are OVER! Thank you for your attention to this matter. President DONALD J. TRUMP

Trump posted the following on Truth Social:

Canada wants the benefits of being a State, without being one!!! They have also charged our great farmers, for many years, massive amounts of Tariffs. No more!!! President DJT

At a press conference Carney said:

In recent days, the United States proposed new terms that were uneconomic, unfair, and undermined the net benefits for Canada and called into question the reliability of any deal. In short, they asked too much and they offered too little. You're at war when you get attacked. We got attacked
