A date has been set for an inquest that will look into a fatal fire that claimed the lives of a family of four in East Gwillimbury in 2013.

Ontario’s Ministry of Community Safety and Correctional Services announced on Monday that an inquest will be held on Sept. 21 to examine the events surrounding the deaths of the Dunsmuir family.

Kevin Dunsmuir, 55, Jennifer Dunsmuir, 51, Robert Dunsmuir, 19, and Cameron Dunsmuir, 16, all died in a house fire on March 29, 2013.

The inquest will last about five weeks, where a jury will hear details from 30 witnesses about fire safety and the response by emergency crews.

An investigation by the Office of the Ontario Fire Marshal showed the fire started in a clogged dryer vent on the main floor. The investigation also showed there was no smoke alarm on the main floor and when the second floor alarm was activated by the smoke, it was too late.

The jury involved in the inquest may make recommendations to prevent similar deaths in the future.

The inquest will take place at Coroners Courts, Forensic Services and Coroners Complex located in Toronto.
