Southwest Middlesex Fire says all residents are accounted for after a house collapsed near Wardsville Sunday morning.
The side of the home on Trillium Drive gave way before the roof caved in around 7 a.m.
No injuries were reported, according to fire officials.
OPP and investigators from the Ontario Fire Marshal's Office were on scene throughout the day Sunday to investigate the "cause and circumstance" of the collapse.
They will be looking into whether the incident was the result of an ignition source, Southwest Middlesex Fire said.
