TORONTO (AP) 鈥� Mark Carney drew international attention as Canada鈥檚 prime minister by warning that must resist by more powerful countries. Now is putting that warning to the test with sweeping that could show how much economic pain Canada can absorb.
late Friday when Canada after Carney concluded the United States was demanding too much in exchange for tariff relief. The U.S. imposed 50% duties Saturday on about $20 billion worth of Canadian goods, and Carney announced dollar-for-dollar retaliation beginning Sept. 8.
鈥淲e鈥檙e going to hit back,鈥� Carney said.
Carney is doing what many other American allies have so far avoided: risking economic pain rather than yielding to tariff pressure.
For Carney, the showdown is the clearest test yet of his argument that must stand up to economic pressure from great powers such as the United States and China, even when it comes at a cost. Canada鈥檚 response could show how countries navigate a world in which long-standing alliances offer less protection and economic ties themselves become sources of leverage.
It could also shape how Carney is viewed at home and abroad, and how other U.S. allies respond to the Republican president.
The trade dispute also has become a test of sovereignty.
Carney said Washington introduced language in the final hours of negotiations that would have restricted Canada鈥檚 ability to make trade deals with other countries. He said that demand was 鈥渦nacceptable鈥� and 鈥渁 question of sovereignty.鈥�
British Columbia Premier David Eby said accepting such a condition would have reduced Canada 鈥渢o the economic equivalent of the 51st state鈥� 鈥� a status .
Canada becomes a test case for the world Carney warned about
Carney鈥檚 message resonated in January when he addressed the World Economic Forum in Davos, Switzerland, as Europe braced for and new tariffs.
Carney said the international order was undergoing 鈥渁 rupture, not a transition.鈥� He argued that sovereignty would depend increasingly on a country鈥檚 ability to 鈥渨ithstand pressure鈥� and warned that middle powers negotiating alone with great powers do so from weakness.
Trump responded a day later by stressing Canada鈥檚 dependence on the United States. 鈥� ,鈥� he said. 鈥淩emember that, Mark, the next time you make your statements.鈥�
The president has repeatedly talked about making Canada the 51st U.S. state and dismissed the allies’ border as artificial. On Sunday, Trump returned to that theme, writing on Truth Social that 鈥淐anada wants the benefits of being a State, without being one!!!鈥� and accusing Canada of charging U.S. farmers 鈥渕assive amounts鈥� of tariffs for years. 鈥淣o more!!!鈥� he wrote.
Seven months since Davos, Canada has become a test case for the world Carney described.
鈥淥ur government understood, before many, that America would transform all its commercial relationships,鈥� Carney said Saturday. He accused Washington of using 鈥渆conomic integration as a weapon鈥� and said its 鈥渟ignature was written in pencil.鈥�
The price of resistance and will Canada show the way?
Historian Robert Bothwell said Canada is uniquely vulnerable to U.S. pressure.
鈥淣o country is more exposed than Canada,鈥� Bothwell said. 鈥淥ther countries have to fear American misbehavior, but none as much as Canada.鈥�
Bothwell said success ultimately means Canada retaining its independence 鈥渋n the face of Trump鈥檚 desire to subordinate it and absorb it.鈥� He said Carney “sees that very well.鈥�
But Canada鈥檚 dependence on the U.S. market makes that difficult.
Nearly three-quarters of Canadian exports go to the United States, whose economy is roughly 10 times larger. Canada can sign new trade agreements, but replacing customers and supply chains built around the enormous U.S. market over decades is considerably harder.
Carney acknowledged retaliation would 鈥渞aise costs and reduce choice for Canadians.鈥�
U.S. Trade Representative Jamieson Greer rejected Canada鈥檚 account of the breakdown in talks, saying Ottawa introduced new demands and backed away from commitments even after Washington offered to reduce tariffs on steel, autos, lumber and other goods.
He said the United States was moving ahead with additional measures in response to Canada鈥檚 retaliation, raising the prospect of further escalation.
The European Union prepared retaliatory tariffs against the United States last year but repeatedly suspended them while negotiating with Washington.
Nelson Wiseman, a professor emeritus of political science at the University of Toronto, said Canada is providing the biggest test yet of whether Carney鈥檚 strategy can work and whether resistance by one middle power could change the calculations of others.
鈥淲ill there be a domino effect? We鈥檒l see,鈥� Wiseman said.
Carney tries to hold the line as anger grows among Canadians toward Trump
Ian Bremmer, president of the Eurasia Group, said Americans underestimate how angry Canadians are with the Trump administration.
鈥淭aking a hard line in response to U.S. policy perceived as predatory 鈥� even with major economic cost to Canada 鈥� is popular among most Canadians,鈥� he said in a social media post.
That anger again spilled into sports over the weekend. Fans in Vancouver and Montreal booed the U.S. national anthem before Major League Soccer matches Saturday, echoing similar scenes early in the trade war last year.
Manitoba Premier Wab Kinew said Canadians should be prepared for a prolonged confrontation and that Trump could emerge weaker after the U.S. midterm elections in November.
鈥淗e鈥檚 got two more years left in office. We should be prepared to duke it out for two years, and then hopefully, sanity will return,鈥� Kinew said.
Carney has framed the confrontation as a test of whether Canada can preserve its independence under U.S. pressure.
鈥淟ast spring, I warned that America is trying to break us so that they can own us,鈥� Carney said Saturday. 鈥淎nd I promised: 鈥楾hat will never, ever happen.鈥� We are keeping that promise.鈥�
