A shooting in Canada, Montreal’s Côte-des-Neiges neighbourhood, that left a police officer and a civilian dead, before the suspected attacker was killed by responding officers, has prompted an ongoing investigation into the motive and circumstances behind the attack. Authorities have confirmed multiple fatalities and said a full inquiry is underway to reconstruct the sequence of events.

The incident occurred on Monday when emergency services responded to reports of gunfire in a residential area of the city. Upon arrival, police encountered an active threat situation that resulted in the deaths of a serving police officer and a civilian identified in local reports as Michael Mizrahi. The suspect was subsequently shot dead at the scene by responding law enforcement personnel.

While official confirmation of the attacker’s identity has not yet been issued by authorities, Canadian media outlets have reported that the suspect is believed to be Seth Hatfield. These reports cite investigative material and documents allegedly recovered in connection with the case. Police have emphasised that formal identification and conclusions regarding motive are still pending verification.

Investigators are also examining a lengthy written document reportedly linked to the suspect, described in media reports as a manifesto of more than 100 pages. According to these accounts, the document outlines extreme ideological views and references a call for violent upheaval against modern societal structures. Authorities have not publicly validated the authenticity or full contents of the document but have confirmed that such material is being assessed as part of the broader investigation.

Law enforcement officials have stated that the investigation is in its early stages and remains highly sensitive. Multiple units are working to establish a detailed timeline of events, including the suspect’s movements prior to the shooting, potential planning activity, and any possible interactions that may shed light on the motive. Digital forensics, witness statements and physical evidence from the scene are all being reviewed.

The shooting has deeply shaken the local community, particularly given that one of the victims was a serving police officer. Officials in Montreal have urged the public to avoid speculation while the investigation continues, stressing that unverified claims circulating on media platforms will be addressed only once confirmed through formal investigative channels. Further updates are expected as authorities continue to analyse evidence and complete identification procedures.
