During an interview with the New York Times, former Canadian Prime Minister Mark Carney discussed preparations made over the past year to address the “extreme tail risk” that U.S. President Donald Trump might order military action against Canada due to his previous threats. Timothy Sayle, a professor at the University of Toronto, confirmed this preparation is valid given recent unpredictable actions by the U.S., such as interventions in Venezuela and threats towards Greenland. The article does not provide specific details about Carney’s preparations but highlights potential scenarios like border incursions or naval presence near Canadian shores.

Story summary

In a recent interview with The New York Times, Prime Minister Mark Carney discussed the possibility that President Donald Trump might order military action against Canada, describing it as an "extreme tail risk" – a highly unlikely but possible scenario. Carney said it would be irresponsible not to prepare for such improbable events, touching on broader topics like F-35 jets and trade issues during his interview. A professor from the University of Toronto agreed that considering this scenario is valid given current international tensions. The BBC reported Canadians' reactions to these concerns, highlighting the unusual nature of preparing for a US invasion despite its low probability.

🔮 So not only are they wasting money on subscriptions nobody’s using, they’re also refusing to tell taxpayers how much of our money they’re wasting.” Assuming a price of $144.52 per licence based on the first group, the additional licenses would have cost another $2.87 million, for a total of $7.67 million.
🔮 The charge is per passenger, so booking flight for a family of four would cost $120.

🔮 When affordability comes up, the Houston government points to its one-point HST cut, but it has never touched the 15.5-cent-per-litre provincial gas tax.” National Post has reached out to the premier’s office for comment.

he → make → Post
The U.S. incursion into Venezuela this year and its threats against Greenland made its allies, including Canada and Europe, take notice, Sayle said. asserted
Sayle → make → notice

they → seem → Iran
So that’s why I can understand the prime minister’s point that it’s maybe very very very low risk but, as he said, can’t be totally ignored.” asserted
he → ’ → point
As to what form a potential invasion might take, Sayle said the “wild unpredictability of the current American administration” made it difficult to predict, but he imagined several small-scale scenarios. uncertain
he → take → scenarios
They included “some sort of hot pursuit of a suspected criminal, or somebody that ICE was seeking, across the Canadian border.” asserted
ICE → include → border
He added: “You could imagine an increase of U.S. forces, like the strengthening of U.S. forces in Canada in some way.” uncertain

Canada → suggest → means
Americans could either publicly or invisibly flex their might and indicate that Canada’s sovereignty wasn’t quite as secure as we’d like to think.” uncertain
we → flex → might
The notion has been ridiculed at high levels. asserted

that → say → ?
“Canada and the United States militaries obviously have worked so closely together for so long,” he said. asserted
he → work → ?
“I’m sure there’s a lot of goodwill and close relationships in the senior ranks, but we are, of course, seeing changes to how general officers are selected in the United States, and who keeps their jobs.” asserted
who → ’m → jobs
Paparo concluded his remarks by saying he will ultimately follow the orders of the commander-in-chief. asserted
he → conclude → chief
“And so we have, I think, lots of protections against this; relationships, friendships, common sense,” said Sayle. asserted
Sayle → have → this
“But these things don’t always govern in a crisis.” asserted
things → govern → crisis
Carney is hardly the first to speculate on the possibility of war between Canada and the U.S. asserted

Brown → draft → them
A Washington Post article from 2005 said the plan called for Canadian soldiers to make for Albany, Minneapolis, Seattle and Great Falls, Mont., at the first signs of a possible U.S. invasion. asserted
soldiers → say → invasion
The article quotes Floyd Rudmin, Canadian author of the 1993 book “Bordering on Aggression: Evidence of U.S. Military Preparations Against Canada,” as saying Brown even entered the country in civilian clothing to do reconnaissance. asserted
Brown → quote → reconnaissance
“He had a total annual budget of $1,200,” said Rudmin, “so he himself would drive to the areas where they were going to invade and take pictures and pick up free maps at gas stations.” asserted
they → say → stations
The plan was terminated in 1928, and many of the documents relating to it were destroyed. asserted
many → terminate → it

invasion → tell → it
Rigby, who spent 14 years with the Department of National Defence, said the Canadian military is supposed to plan for all scenarios. asserted
military → spend → scenarios
“They’re very good at it and, given the current situation in the world, given the current state of Canada-U.S. relations, given the current state of U.S. foreign policy, I’m not completely surprised that they’re looking at possible scenarios. asserted
they → ’re → scenarios
Carney’s comments to the New York Times also included talk of the trade war, a fact Sayle calls salient. asserted
Sayle → include → war
“It’s a signal to the whole world,” he said. asserted
he → ’ → world
“I don’t think it’s a significant signal to the American government, but maybe a signal more broadly to American politicians and industry leaders as to how seriously Canada is taking this current difficult period with the United States, and I think in some ways it might strengthen the Canadian negotiating hand when it comes to trade issues, because the prime minister is signalling that this was a sort of existential moment for Canada.” uncertain
this → think → Canada
He added: “Even though it’s an American news outlet, this is a major headline in an international paper that Canadians will see too. asserted
Canadians → add → that
So … there may be these instrumental reasons for doing it, like the trade negotiations, and signalling to Canadians just how serious he’s taking this moment. uncertain
he → do → moment
But it’s obviously a pretty important signal of the state of the relationship with the United States, and how different that is than anything in our living memory.” asserted
that → ’ → memory
