On October 22, 2014, gunfire erupted at Canada’s National War Memorial in Ottawa, where Corporal Nathan Cirillo, a young soldier standing ceremonial guard, was shot and killed. The gunman then stormed Parliament Hill, sending lawmakers into lockdown as security forces scrambled to respond. Within minutes, he was fatally shot inside the Centre Block. The attack shocked the nation, exposing vulnerabilities at the heart of Canadian democracy and sparking urgent debates about security, radicalization, and resilience in the face of terror.
