The incident began when a security alarm went off at a chalet on Lesage St., police said.
The Quebec Independent Investigations Office (EIB) has opened an investigation into the fatal shooting on Thursday night by the Sûreté du Québec of a man in Sainte-Adèle in the Laurentians.
According to information provided to the EIB by the SQ, the police were called to a chalet on Lesage St. at 9:45 pm after a security alarm was activated.
Once at the scene, officers unsuccessfully tried to communicate with a 44-year-old man they found inside the building.
Police said the man reached into a backpack and officers tried to subdue him with a stun gun.
Police told the EIB that the man then removed a firearm from his backpack, at which point one of the officers opened fire, hitting the man at least once.
The man was later pronounced dead at the hospital.
Called every time a death or serious injury occurs during a police operation in Quebec, the EIB has assigned five investigators to the case and will receive technical support from the Montreal Police Department.
