Toronto -There was no smoke alarm on the main floor of a North York townhouse where a woman and two of her children died in a fire early Saturday. That from Jim Fisher with the Ontario Fire Marshal’s office, who says there was an alarm on the second floor, but it’s not known if it was working.

Toronto Community Housing tells CFRB News that the fire alarms were all in working order when they were last inspected in February of this year. Sadly, the unit was due for another inspection next month.

Fisher says Toronto Fire checked a number of units in the townhouse complex and found as many as eight that either had no smoke alarm or it wasn’t working. They have all since been fixed.

The cause of the fire has not yet been determined and may never be known because the townhouse was so severely damaged.

Three other children escaped the burning home and were found outside by firefighters when they first arrived on the scene. They were taken to hospital with minor burns and smoke inhalation and have since been released into the custody of relatives.
