The cause of a house fire early Wednesday morning in Sarnia will go down as undetermined.
Firefighters were called to a blaze on Vidal Street South near Devine Street at around 4:30 a.m.
Upon arrival, crews found flames venting from a first-floor rear bedroom of the two-storey structure, which were quickly extinguished.
They said there were two potential ignition sources that could not be eliminated, and therefore the exact cause is unknown.
Damage was estimated at around $100,000, and there were no injuries.
