Firefighters say a blaze broke out at the Britannia townhouse at 2949 Penny Dr., which is near Michele Drive in the city’s Britannia neighbourhood, just before 7:30 p.m. Wednesday.
When they arrived, firefighters found smoke and flames shooting from all three floors of Unit 35.
Neighbours said a woman had managed to escape the unit, but they saw her run back into the burning building claiming she was going to rescue her dog.
"She went in to get her dogs, but I didn't see her get out," said neighbour Kate Rodriguez, "I don't know, I only saw the German Shephard get out, I didn’t see the Dalmatian."
Neither she nor the dog came back out. Fire officials later confirmed the body of a woman and a dog were found in the unit.
"Once a pet is inside or you think it is inside, there is nothing you can do at the time," Ottawa Fire Capt. Robert LeClaire said. "If you see fire or flames inside a burning building, you should stay out."
'House basically exploded', neighbour says
Dozens of neighbours who surrounded the complex as firefighters tackled the blaze also described a blast before the fire erupted from the building.
"The house basically exploded," said neighbour Mackenzie Cook.
Flames then spread to another unit and caused some damage there before it was under control about one hour after it started, firefighters said.
LeClaire said the fire easily could have spread further.
Paramedics said two firefighters in their 40s suffered minor lower-body injuries while tackling the blaze, including one who hurt his foot. They were taken to hospital in stable condition.
The cause of the fire is under investigation. Investigators with the Office of the Ontario Fire Marshal and with Ottawa Fire Services are looking into the incident.
While responding to the emergency, paramedics said a 25-year-old pregnant woman in labour came to them at the fire scene. She was then taken to hospital.
