Two senior government officials, not authorized to discuss this matter publicly, told the Globe and Mail that Canadian Armed Forces planners modelling a US invasion from the south, expect US forces to overcome Canada’s strategic positions on land and at sea within a week, and possibly as quickly as two days.
Canada does not have the number of military personnel or the sophisticated equipment needed to fend off a conventional American attack.
Canada would have a maximum of three months to prepare for a land and sea invasion.
In response to a US invasion, CAF planners envisions unconventional warfare in which small groups of irregular military or armed civilians would resort to ambushes, sabotage, drone warfare, and hit-and-run tactics. The aim of such tactics would be to impose mass casualties on US occupying forces.
General Jennie Carignan, Chief of the Defence Staff, has already announced her intention to create a 400,000-plus-strong reserve force of volunteers. Conscription has been ruled out for now.
Canada would likely call on France and/or Britain, nuclear-weapon states, to provide support and defence for Canada against the US.
Retired major-general David Fraser, who commanded Canadian troops in Afghanistan alongside the US, said Canada can count on support from European countries, Britain, Japan, South Korea and other democratic nations.
