Quebec provincial police are investigating the deaths of three people in Notre-Dame-des-Prairies in the Lanaudière region.

The deceased include a father and his two children, according to Sûreté du Québec spokesperson Catherine Bernard.

Ian Lamontagne, 46, who was previously identified as Ianik by Radio-Canada sources, and three-year-olds Antoine and Tristan, were identified as the deceased by the coroner Monday.

Bernard says police are investigating it as a double murder-suicide.

Police say they received a 911 call at about 2 p.m. Saturday. Officers were dispatched to a residence on Patrick Street where they found three bodies.

A perimeter was established and a command post was set up. Over the next few hours, police will collect witness testimonies and analyze the scene.

Notre-Dame-des-Prairies Mayor Suzanne Dauphin said the deaths are reminders that life is fragile and precious and that mental health issues can affect everyone, regardless of their age or situation.

"As a society, we must also commit ourselves to preventing such events in the future," she said in a statement Sunday. "This means stepping up our efforts to recognize the warning signs of distress and despair among our loved ones."
