Overview
- The shooting occurred Monday in Côte‑des‑Neiges when officers who responded to a 911 call exchanged fire with a gunman, leaving a Montreal police officer and a civilian dead.
- Quebec’s coroner named the suspect as 25‑year‑old Seth Scott Hatfield of Lethbridge and officers seized a long gun plus a roughly 104–105 page manifesto that is being forensically reviewed.
- The Bureau des enquêtes indépendantes, the Quebec coroner, the RCMP and provincial police have opened parallel probes and the RCMP circulated an intelligence bulletin to other forces about the document.
- The two confirmed victims are Constable Mohamed Lamine Benredouane, 34, and civilian Michael Moshe Mizrahi, 68, and a second officer who was critically wounded is now reported to be stable.
- Investigators warn motive and any wider links are not yet proven, and officials note the manifesto’s reported incel and anti‑police themes echo ideologies tied to past Canadian attacks, raising security and community concerns.
