What happened

Case facts: Incident type: Shooting/mass violence | Method/weapons: Attack type: firearm attack.

On October 22, 2014, Michael Zehaf-Bibeau shot and killed Corporal Nathan Cirillo at the National War Memorial and then moved to the House of Commons area, where additional shots were fired and the attacker was stopped. A House of Commons report summarizes this sequence and the security response context.

An RCMP review process examined preparedness, protective actions, and coordination related to Parliament Hill response, producing recommendations for future protective operations and external engagement during such incidents.

What we still need: a single authoritative, time-stamped chronology across the War Memorial and Centre Block, including confirmed injury counts, officer actions, and command decisions.
