Canadian Prime Minister Mark Carney says he studied the possibility of a U.S.-led military invasion of Canada, framing it as an ‘extreme tail risk’ worth planning for as trade tensions with President Donald Trump keep escalating.
What Carney actually said
In a lengthy New York Times interview, he declined to discuss in detail what that examination involved, but suggested it would be irresponsible not to prepare for what he called ‘extreme tail risk.’
‘I think you have a responsibility in these roles to look at extreme tail risk. That’s just risk management. That’s not a base case,’ Carney told the Times, adding that ‘it would be irresponsible not to’ be prepared.
Reporters asked him for specifics on what sort of actions Canada had taken to prepare, but Carney refused to do so. ‘He did not use the word invasion to be clear, that was our word.’
Why this is on the table
Carney made the statement in an interview with The New York Times published Wednesday, saying he weighed the possibility after President Donald Trump began referring to Canada as the 51st state.
Trump, who told journalists in 2025 he would be willing to use ‘economic force’ to coax Canada into political union with the U.S., has repeatedly referred to the country as the ‘51st state’ and to Carney as ‘governor.’

The military planning behind the comments
The Canadian Armed Forces modeled an American assault for the first time in one century, envisioning unconventional warfare tactics mirroring the Taliban’s 20-year war in Afghanistan to counter Canada’s conventional military limitations.
Military planners anticipate American forces could overcome strategic positions within two days to one week, forcing Canada to rely on sabotage and drone warfare given its personnel and equipment shortages.
Trade war backdrop and the pivot to Europe
Tensions between Washington and Ottawa intensified in recent months after trade negotiations between the two countries fell apart. Trump launched a tariff war in response, with the U.S. and Canada slapping tariffs on each other’s goods. Trump has also repeatedly pushed to acquire the U.S.’s northern neighbor, which Canada has rebuffed.
Trump’s trade war has pushed Canada to deepen its ties with the European Union rather than move closer to his vision of Canada as the 51st U.S. state. Carney has been calling for a ‘unique alliance’ between Canada and the EU as relations deteriorate with the U.S.
‘Starlink, we will diversify away from, no question,’ Carney said, referring to Elon Musk’s satellite company.
Options market and stocks to watch
Watch for cross-border names and defense-adjacent tickers to react as the rhetoric ratchets up:
- TSLA: Carney’s comments on diversifying away from Starlink put SpaceX in focus; watch for spillover sentiment on Elon Musk-linked names.
- LMT: Canada’s F-35 procurement is under review, so Lockheed Martin headline risk stays live.
- F and GM: Deeply exposed to U.S.-Canada auto supply chains and any further tariff escalation.
- EWC: The Canada ETF is the cleanest single-ticker read on how markets price Ottawa-Washington risk.
