At least two multi-family residential units that were under construction were destroyed by fire early Saturday morning.
Firefighters were called to the 0-100 block of Sage Hill Terrace NW around 12:50 a.m. and arrived to find two homes fully involved in flames that were spreading to a third unit.
Global News counted at least seven vehicles, parked along the street, that were also damaged by the fire.
A second alarm was called as firefighters quickly initiated defensive operations to prevent the flames from spreading further.
Fire investigators are looking into what caused the blaze.
