"At the time when they were doing their primary searches, there was a deceased occupant found in the basement."

A second person was assessed by paramedics but their condition is not known at this time.

"There was one other occupant in the home. That occupant was outside ont eh street when the fire crews arrived," Giffin said. "That person has been transported to hospital." 

Giffin added that multiple fires were found in the basement when crews arrived on scene.
