There were several fires inside the eight-bedroom, seven-bathroom residence and firefighters were still at the scene early Monday.
The property, worth an estimated $19.5 million, was visited by Montreal police arson investigators Monday morning after the flames spread so quickly overnight that three alarms were sounded summoning 80 Montreal firefighters to the scene.
