Prime Minister Mark Carney said Canada examined the possibility of U.S. military action as an “extreme tail risk”, while insisting that an American invasion is not Ottawa’s base-case scenario, according to CTC News.

The remarks were made in an interview published on 23 September, amid a sharp deterioration in the economic relationship between the two countries and repeated statements by Donald Trump about Canada becoming the 51st U.S. state, according to CTC News.
