Firefighters were called to an apartment complex in the Queen Mary Park neighbourhood after a barbecue, they believe, started a fire on a balcony.
A Triple Mar Terrace third-floor balcony was seen burning Saturday afternoon at 11302 109 Avenue.
Six unites responded to the blaze.
Firefighters said it was a reminder to keep a clean grill.
"Make sure they are clean because I'm not sure how it started, but just be careful with your barbecues on the balcony," acting fire chief Brian Hermanutz said.
Most of the damage was contained to the exterior of the building.
