Trump Warns PM Carney: Canada's Economy Will 'Collapse' If He Keeps Making Him 'the Enemy'

President Donald Trump issued a stark warning to Canadian Prime Minister Mark Carney on Thursday, declaring that Canada's economy will "collapse" if its leaders continue to portray him as "the enemy." The threat comes amid an escalating trade war between the neighboring countries after negotiations over a new agreement broke down last month.

WASHINGTON – President Donald Trump on Thursday took to Truth Social to issue a blunt warning to Canadian Prime Minister Mark Carney, saying that portraying him as an enemy is a dangerous political gamble that could backfire catastrophically.

"It is very good for Canadian Politicians like Prime Minister Carney to make President Donald J. Trump 'the enemy,' until their Economy collapses, then it will prove to be very bad for Politics — Worse than anything that has ever happened to a Canadian Politician. Just watch!" Trump wrote .

The extraordinary warning comes as trade relations between the U.S. and Canada have deteriorated sharply. In August, Washington imposed 50% tariffs on approximately $20 billion worth of Canadian goods after trade talks collapsed on August 21 . Canada has responded with retaliatory tariffs covering nearly $20 billion in U.S. products, with duties ranging from 15% to 50%, set to take effect on September 8 .

What Sparked the Clash?

The breakdown in negotiations has been marked by finger-pointing from both sides. Canadian officials say they walked away after the U.S. introduced last-minute demands they deemed unacceptable, including provisions that would have:

• Restricted Canada's ability to sign trade deals with other countries

Carney has been unequivocal in his rejection of those terms. "We're not going to — of course, we're not going to accept those terms," he said . He accused the Trump administration of seeking an arrangement that could leave key Canadian industries "gradually wound down" and ultimately wiped out.

But the Trump administration has offered a starkly different version of events. Commerce Secretary Howard Lutnick claimed Canada added "crazy ideas" in the final hours of negotiations in order to terminate the deal for domestic political reasons .

"We had a deal, we shook hands, the president announced it, everybody was positive. Canada made the decision for political purposes, they wanted to walk away. This is politics only," Lutnick said .

The Growing Rift

The trade dispute has taken on increasingly personal and confrontational tones. Trump has repeatedly taunted Canada, calling it the "51st state" and suggesting it cannot survive without the American market . Vice President JD Vance added fuel to the fire on Monday, mocking Canada as "a state" that "quite literally would get invaded by a foreign country were it not for the umbrella of protection provided by the United States of America" .

The tensions have also spilled over into a separate dispute over the name of Lake Ontario. Trump issued an executive order renaming it "Lake America," a move that has proven deeply unpopular even among his own supporters .

Carney has pushed back sharply against the administration's rhetoric. "Stop doing memes, stop throwing shade and stop trying to be tough," he said, adding that Canada remains ready to negotiate when the Americans are serious .

When asked about comments from "unelected" U.S. cabinet members explaining the collapse of trade talks, Carney dismissed them. "I don't think, with all respect, appointed, unelected cabinet members in the United States are experts on Canadian politics," he said in Thunder Bay, Ontario .

Public Opinion: Americans Oppose the Clash

According to a Reuters-Ipsos poll conducted in recent days, Americans overwhelmingly oppose Trump's approach to the Canada dispute:

The poll found that significantly more Americans say the United States is more responsible for the dispute (46%) than say Canada is (12%) . Ten times as many people expect the tariffs to mostly hurt their personal financial situation (40%) rather than help it (4%) .

What's Next?

Canada is moving forward with its retaliatory tariffs set to take effect on September 8. The government has also announced a C$7.5 billion relief package for businesses and workers affected by the U.S. tariffs .

Despite the escalating rhetoric, Carney has left the door open for negotiations. "We're ready to sit down and strike that deal when the Americans are ready," he said — but made clear that would only happen when the U.S. recognizes where Canada's "red lines" are and respects them .

Trump, meanwhile, appears to be doubling down. His warning that Carney's anti-Trump stance could lead to economic collapse is the latest salvo in a war of words that shows no signs of abating. And for now, the president's closing line — "Just watch!" — remains a fitting summary of a relationship that has reached its lowest point in modern history.
