Prime Minister Mark Carney has examined the 'extreme tail risk' of U.S. military action against Canada, he told the New York Times. Carney’s comments came in response to questions about whether he had taken the possibility of American aggression against the Canadian state seriously.

The preparations specifically address the risk that Donald Trump could order a U.S.-led invasion of Canada, according to CTV News. Carney indicated that evaluating such scenarios is part of his assessment of tail risks affecting the country.
