The U.S. needs ​to “start being serious and stop trying to be ‌tough” before talks on a possible trade deal ​with Canada can restart, Prime Minister ⁠Mark Carney told reporters on Tuesday (September 1, 2026).

Canada walked away from negotiations on an agreement to avoid additional U.S. tariffs on ‌August 21, saying the American side had made unacceptable last-minute demands.

Since then U.S. ‌President Donald Trump has declared that Lake Ontario ‌should ⁠be renamed Lake America, described Canada’s leaders ⁠as “the worst” he has to deal with, and repeated assertions that Canada is ripping off the U.S.

He also posted ​an AI-generated meme showing ‌Canadian geese with Trump’s distinctive hairstyle marching under a U.S. flag.

Mr. Carney said there was still a chance to strike a mutually beneficial trade ‌deal that respected Canadian sovereignty.

“And when the ​Americans stop doing memes, stop throwing shade, stop trying to be tough and ⁠start being serious about having those discussions, we can have those discussions,” Carney said, adding that recent U.S. ‌actions were “not constructive.”

U.S. officials have challenged part of the Canadian narrative as to why the talks collapsed, saying there was a good deal to be had on the table. Carney said Ottawa had never felt the proposed terms would ‌be adequate, especially when it came to the highly integrated ​auto sector.

“The attitude of the United States… has been one that the core ⁠Canadian industries either would be subsidiaries, effectively, of the United ⁠States industries, or (Washington) would put in place terms where those industries would be gradually ‌wound down in Canada and wiped out,” he said.

“Of course, we’re not going to ​accept those terms.”

U.S. President Donald Trump hit back at Canada on Sunday (August 23, 2026) after Prime Minister Mark Carney announced retaliatory tariffs on the United States following a breakdown in trade negotiations.

“Canada wants the benefits of being a State, without being one!!!” Mr. Trump said in a post on Truth Social.

“They have also charged our great farmers, for many years, massive amounts of Tariffs. No more!!!” he said.

Mr. Carney said on Saturday (August 22, 2026) that new Canadian tariffs would take effect on September 8, notably targeting the U.S. steel and dairy industries.

New 50% U.S. tariffs impacting about $20 billion worth of goods, or 5.5% of Canadian exports to the U.S., came into force Saturday.

Canadian Prime Minister Mark Carney became a symbol of middle power resistance after a celebrated speech earlier this year, but he is expected to be more muted in his criticism of U.S. President Donald Trump at an upcoming summit in Europe.

Mr. Carney’s speech at the World Economic Forum in Davos, Switzerland, helped make him an international political star in January, when he declared the global rules-based order over and condemned coercion by great powers on smaller countries.

The Prime Minister received widespread praise and attention for his remarks and upstaged Mr. Trump at the gathering.

But the Group of Seven summit of industrialised democracies that begins on Monday (June 15, 2026) in France comes ahead of the scheduled July 1 review of the U.S.-Mexico-Canada Agreement, or USMCA, the latest iteration of the North American free-trade pact that has intertwined the economies of the United States, Mexico and Canada since the early 1990s. It is a crucial moment in trade talks, and Mr. Trump said this week that he may not renew the deal.

More than 70% of Canada’s exports go to the U.S., so preserving the accord is critical for Canada.

Canadian historian Robert Bothwell said Mr. Trump is more of a problem for Mr. Carney “than anybody else because we are more exposed to the United States than anybody else.”

Mr. Trump leaves for the G7 right after he hosts UFC fights at the White House on Sunday (June 14, 2026) for his 80th birthday.

The summit will unfold as tensions are ramping up between Mr. Trump and Canada. One of the world’s most durable and amicable alliances — born of geography, heritage and centuries of common interests — is broken, as seen in several recent examples of tension between leaders.

Ontario Premier Doug Ford, the leader of Canada’s most populous province, had a reception with the U.S. Chamber of Commerce in Washington cancelled Monday at the last minute. Vic Fedeli, one of Ford’s ministers, said if Mr. Trump forced the chamber to cancel, “Ford should be wearing that as a badge of honour.”

Mr. Trump said again this week that the U.S. doesn’t need anything that Canada has. Mr. Carney has set a goal for Canada to double its non-U.S. exports in the next decade, saying Mr. Trump’s trade war is causing a chill in investment.

In other developments, the opening of a major Canadian bridge across the Detroit River that Mr. Trump previously threatened to block was delayed on Thursday due to unresolved issues.

Mr. Trump’s actions, including launching a trade war and suggesting Canada become the 51st U.S. state, have infuriated Canadians and created the political environment for Carney to win the job of prime minister after promising to confront Mr. Trump.

Trump administration officials keep noting that only two countries, China and Canada, retaliated against America in the trade war. U.S. Trade Representative Jamieson Greer says Canada’s retaliatory measures are a major issue in talks.

Mr. Carney has downplayed Trump’s most recent comments about Canada becoming the 51st state.

Canada and Mexico want the USMCA to be renewed for another 16 years. Mr. Trump has mused about withdrawing from it. More likely it will be subject to annual reviews for the next 10 years.

Mr. Carney will meet with French President Emmanuel Macron on Friday (June 12, 2026) in Paris ahead of the summit in Evian-les-Bains, France. The Prime Minister will also travel to Ireland this weekend to meet with the Irish Prime Minister in a bid to diversify trade away from the U.S. This is Mr. Carney’s ninth trip to Europe in the 15 months since he became Prime Minister in March 2025.
