Seven people are homeless after a highrise building fire inside the bedroom of a main floor apartment unit.

Ottawa firefighters responded at about 4:17 p.m. on Wednesday for a fire at 2660 Norbery Cres., which is in the Riverside Park neighbourhood.

When they arrived, firefighters reported heavy smoke in the lobby of the building and the fire was escalated to a third alarm soon after.

The fire started in the bedroom of unit 126, which was destroyed. Fire officials said the seven people living in the unit are now left without a place to live.

Residents on the building’s first floor were not allowed to return to their apartments Wednesday night, while those living on the second floor to the tenth floor were allowed back inside.

Total damage is estimated $430,000 to the unit and the first floor of the building.

The cause is under investigation.

Salvation Army and Red Cross workers were also on scene to help residents.
