Prime Minister Mark Carney claimed, in an interview on Sept. 23, that it would be “irresponsible” for Canada not to prepare for the “extreme tail risk” of U.S. military action against Canada. He refused, however, to provide any details.
How would Canada respond to an invasion? A Globe and Mail article from Jan. 20 provides the answer. The military has apparently developed a contingency model for the unlikely event of a U.S. invasion. Canada would mount a military defence, but it would be breached within two to seven days. Resistance would then shift to an insurgency on the Afghan model, intended to impose high costs on the invading force. Insurgents would engage in hit-and-run tactics, sabotage, ambushes and planting improvised explosive devices.
