Air defense is organized by geographic regions, each responsible for defending the airspace within its area and carrying out a range of tasks to maintain security. The Canadian Region is the NORAD element dedicated to Canada’s airspace, handling surveillance and warning, airspace control, threat identification, and the coordination of intercepts and response actions with Canadian forces and NORAD partners. This regional focus makes it the entity that directly executes a variety of tasks to defend Canadian airspace.

The other options correspond to territories outside Canada: the Alaskan region covers Alaska; the Continental United States region covers the continental United States; and the Eastern Air Defense Sector is a US sector responsible for a portion of the eastern US airspace. Hence, they do not defend Canadian airspace.
