Canada’s old air defenses are not ready for today’s fast-moving wars. Recent conflicts show that cheap drones and high-speed missiles can easily slip past outdated systems, leaving cities and power grids at risk. The government is fast-tracking the purchase of new missile systems and smart anti-drone tech. By using a "layered" approach with many mobile sensors, they can catch threats from different heights and speeds at the same time. This upgrade keeps people safer by protecting essential services from aerial strikes. It also helps Canada stay a strong, reliable partner in global security, ensuring the military is prepared for modern high-tech challenges.
