Police said the suspect opened fire after officers responded to a report of a gun at a hotel window.
MONTREAL, Quebec — A Montreal police officer, a civilian and a suspected gunman were killed Monday after police responded to a report of a person with a long gun at a Hilton hotel in Côte-des-Neiges, officials said.
The shooting brought a large police response to one of Montreal’s busy west-end neighborhoods and marked the first time in 24 years that a Montreal officer was killed in the line of duty. Police Chief Fady Dagher said investigators were still working to determine the gunman’s motive and who fired the shot that killed the civilian.
Dagher said emergency services received a call around 11:35 a.m. about a person pointing or holding a gun from a hotel window. Officers arrived and were met with gunfire. The chief said the suspect was armed with a long gun and that officers returned fire, killing him. “It’s a very, very sad day. It’s a nightmare,” Dagher said. Police later identified the slain officer as Constable Mohamed Lamine Benredouan, 34, who had served with the force since 2021.
A second officer was seriously injured and was reported in stable condition. Officials said a civilian also died, but they had not confirmed who shot that person. Videos circulating online appeared to show a person with a long gun outside the hotel as officers exchanged fire. One witness, Jacob Coutu, said he was working nearby when he heard several shots, then saw many officers arrive. Coutu said he later heard what sounded like 30 or 40 gunshots.
The shooting led public safety officials to issue an emergency alert warning of an armed and dangerous suspect. Residents were told to shelter in place while police secured the area. The alert caused temporary closures on the Décarie expressway and shut down parts of two subway lines. Police later said there was no longer an active threat and that they were not looking for another suspect.
Quebec Domestic Security Minister Ian Lafrenière said an independent police watchdog would examine the case because deaths and injuries occurred during a police operation. He said the Royal Canadian Mounted Police and other agencies were consulted before authorities concluded the shooting was not a terrorist attack. Officials also said they were reviewing reports of possible written material connected to threats against police.
Authorities asked the public not to share graphic videos of the shooting out of respect for those killed. Dagher said the death of Benredouan had shaken the department and the city. The investigation remained active Monday evening, with police still processing several scenes in Côte-des-Neiges and trying to establish a full timeline of the attack.
