What happened

Prime Minister Mark Carney says he has considered the possibility of American military action against Canada, and that the Canadian Armed Forces had examined potential responses.

Why it matters

Such a scenario remains extraordinarily unlikely, but that’s precisely why it belongs in contingency planning.

Common ground

Serious governments do not dismiss low-probability, high-consequence risks simply because they appear remote.

Perspective signals
