Canadian military forces are working through scenarios for conducting guerrilla warfare in the event of an invasion by the United States, The Globe and Mail reported, citing sources.

According to the newspaper, the armed forces are considering insurgency tactics similar to those used by the Afghan mujahideen. Sources say the military expects the US Army would begin an offensive from the south, seizing strategic positions on land and at sea within a week, and possibly even within two days.

At the same time, Canadian command reportedly acknowledges it does not have enough soldiers and weapons to repel an American attack directly, meaning it would have to rely on methods such as sabotage and ambushes using drones.

The outlet notes that relations with the US military remain positive for now.

One source said a possible signal of a future attack could be a statement from Washington ending the partnership within NORAD. After that, in theory, US forces could receive an order to seize Canada by force. The newspaper уточняет that the entire modeling process was purely introductory, and Canada’s leadership does not consider an invasion by its neighbor even remotely likely.

In early January, Bloomberg reported that Canadians fear becoming the next target of US President Donald Trump after Greenland and Venezuela.

In 2025, amid disagreements over potential US tariffs on Canadian goods, Trump called Canada’s outgoing Prime Minister Justin Trudeau the «governor of the great state of Canada." Later, Trump said Canada could avoid Washington’s trade duties and receive military protection if it became part of the United States.
