What Is NORAD?

The North American Aerospace Defense Command, known as NORAD, is the institution through which Canada and the United States jointly watch over and defend the airspace of the continent. It is one of the most integrated defence arrangements between any two countries in the world, and for Canada it is both an asset and a constraint: it guarantees a seat at the table on continental defence, and it ties Canadian security tightly to American priorities.

Background

NORAD was created in 1958, at the height of the Cold War, when the principal threat to North America was Soviet bombers flying over the Arctic. It began life as the North American Air Defense Command and was renamed the North American Aerospace Defense Command in 1981 to reflect a broader remit. The command has been renewed by agreement between Ottawa and Washington roughly every decade since; in 2006 the agreement was made permanent, and a maritime warning mission was added.

What makes NORAD distinctive is that it is genuinely binational. A single commander — always a United States officer — leads a command staffed by both American and Canadian personnel, and the deputy commander is always Canadian. Canadian and American officers sit side by side, and Canadian officers can direct American forces within the command’s mission, and vice versa. No other U.S. military command shares authority with a foreign country in this way.

Key actors

NORAD’s headquarters is at Peterson Space Force Base in Colorado Springs, Colorado, with its operations centre historically associated with the hardened complex inside nearby Cheyenne Mountain. The command is organized into three regions: the Canadian region, headquartered at Canadian Forces Base Winnipeg; the Continental U.S. region; and the Alaskan region.

On the Canadian side, the Royal Canadian Air Force provides fighter aircraft, personnel, and the northern radar infrastructure on Canadian soil. The Department of National Defence and the minister of national defence set Canada’s policy, while overall direction flows from agreement between the Canadian and American governments. Norad’s commander reports to both the U.S. president and the Canadian prime minister.

What NORAD does

NORAD has three missions. Aerospace warning means detecting and characterizing anything flying toward or over North America — aircraft, missiles, and increasingly objects in space. Aerospace control means maintaining sovereignty over the continent’s airspace, including intercepting unidentified or unauthorized aircraft. Maritime warning, added in 2006, means sharing awareness of activity in the maritime approaches to the continent, though it does not give NORAD command of naval forces.

In practice, this is the command that scrambles fighter jets when an unidentified aircraft enters North American airspace, tracks ballistic missile launches worldwide, and — in its most public ritual — “tracks Santa” each December, a tradition dating to 1955.

Numbers

NORAD’s most consequential current story is money. In June 2022, Canada announced a plan to invest roughly C$38.6 billion over 20 years in continental defence and NORAD modernization. The centrepiece is the replacement of the aging North Warning System — a chain of radar stations across the Arctic built in the 1980s — with new Over-the-Horizon Radar systems capable of detecting threats far sooner and at far greater range. The package also funds new infrastructure to support fighter operations in the North, additional air-to-air refuelling capacity, and upgraded command-and-control systems.

This modernization sits alongside Canada’s separate decision to purchase 88 F-35A fighter jets to replace its CF-18 fleet — the aircraft that will fly the bulk of Canada’s NORAD missions for the coming decades.

Policy stakes

NORAD forces a recurring question for Canada: how much is enough? Modern threats are no longer just bombers over the pole. They include advanced cruise missiles, hypersonic weapons, and small, hard-to-detect aircraft and drones — threats that can approach from any direction and that the original radar architecture was never designed to catch. Closing that gap is expensive, and much of the required infrastructure sits on Canadian territory.

A second, harder question is missile defence. NORAD provides warning of a ballistic missile attack, but Canada has, since 2005, chosen not to participate in the U.S. ballistic missile defence system that would attempt to shoot such missiles down. That choice is periodically revisited, and it remains one of the most significant open decisions in Canadian defence policy.

Underlying both is the alliance logic of continental defence: Canada cannot defend its airspace alone, and the United States will defend North America with or without Canadian participation. NORAD is the mechanism that ensures Canada helps shape how that defence is done, rather than simply having it done around it. The price of that influence is sustained investment — which is why the modernization timeline, and whether Ottawa funds it on schedule, is the indicator to watch.
