Overview
- A lone gunman opened fire at an apartment entrance in Côte‑des‑Neiges, and police who responded engaged the attacker before he was shot and neutralized.
- Three people died in the incident: a Montreal police officer, a local resident, and the assailant; a policewoman was gravely wounded and is now in stable condition.
- Officers seized a long gun at the scene and secured a multi‑block perimeter that temporarily closed Autoroute Décarie during the response.
- Authorities say the motive is unknown and the Bureau des enquêtes indépendantes will take over the criminal investigation while Québec runs a crisis cell to support local services.
- Graphic videos circulated online showing a camouflaged suspect and wounded officers but those images have not been independently verified and officials have urged caution as they gather evidence and interview witnesses.
