NORAD Modernization

Canada's NORAD modernization program represents the largest Canadian defense investment in a generation, with CA$38.6 billion committed over 20 years to upgrade North American aerospace defense. Key elements include new over-the-horizon radar systems to replace the aging North Warning System, improved space-based surveillance, advanced command and control infrastructure, and enhanced capability to detect and track hypersonic and cruise missile threats approaching through the Arctic corridor.

NORAD modernization matters because the threat environment has fundamentally changed since the Cold War. Modern threats include hypersonic missiles, cruise missiles that can fly below radar coverage, and potential attacks from the Arctic — a direction that was previously considered secure. The existing North Warning System, built in the 1980s, cannot detect these newer threats. Without modernization, North America faces a growing detection gap.

The strategic context is Canada's alliance relationship with the United States. NORAD is a binational command, and Canada's willingness to invest in modernization directly affects the credibility of the alliance and Canada's voice in continental defense decisions. The investment also drives technology development in radar, sensors, AI-powered data fusion, and autonomous systems — capabilities with broader applications in Arctic surveillance and sovereignty.
