Flames lit up the night sky on Fifth Ave. between Birch and Balsam Sts. Sunday night.
Timmins fire chief Scott Atkinson says several calls came in around 10:00pm about the fire in an unoccupied, multi-unit building. Before mounting a defensive attack to put it out, firefighters did a quick search to confirm there was no one inside.
The blaze was under control by about 3:00am.
