A fire broke out at a single-storey house just outside of Acton late last night.
Heavy black smoke was visible for kilometres, prompting multiple 911 calls. Crews from the Halton Hills Fire Department arrived at 22 Side Road, west of Regional Road 25, around 10 p.m., where they found the roof of a bungalow had already collapsed.
Firefighters used 65-millimetre hose lines in defensive operations to contain the flames.
The home was vacant and undergoing renovations at the time of the fire, and no injuries were reported.
The cause of the fire and the extent of the damage remain unknown.
