A 19-year-old girl and both of her parents were killed in a house fire in Brampton Tuesday morning and the cause of the deadly blaze is currently under investigation.

The fire broke out at a residence on Madison Street, in the area of Dixie Road and Williams Parkway, shortly after 4 a.m.

Five fire trucks initially responded to the call and when crews arrived on scene, flames could be seen coming through a front window.

Brampton Fire Chief Michael Clark said it took firefighters approximately 10 minutes to get the blaze under control.

When crews were able to gain entry to the residence, they found three people dead inside bedrooms in the rear of the semi-detached back-split home.

Clark said prior to the arrival of first responders, an occupant of the basement apartment was able to rescue a young girl trapped on the main floor of the home.

Sheldon Teague told CTV News Toronto that he was in the basement when he smelled smoke and heard screams coming from the main floor unit.

“I looked up at the vent and saw there was smoke coming out. So I put on my shoes right away, went outside and I already noticed the flames and smoke coming out the top of the house,” he said Tuesday.

When he opened the door to the main floor, he said he couldn’t see anything through the smoke.

“It was burning my eyes. I had to run back outside and get my friend's phone, turn on a flashlight and try to direct whoever I could to the front door,” Teague said.

He said more screams could be heard coming from the house and he eventually spotted the little girl in the hallway.

“I told her to crawl towards me. She said that she really couldn’t so I guess she was pretty badly hurt. So I just ran in through the smoke quickly, picked her up, put her outside.”

The child was transported to a Toronto hospital to be treated for third-degree burns and smoke inhalation.

Police have not yet released the age or gender of the victims or their relationship to one another but CP24 has confirmed that the three victims are 19-year-old Amina Kapadia and her two parents.

Kapadia’s nine-year-old sister Zoya remains at SickKids Hospital in serious condition.

The Office of the Fire Marshal, Peel Regional Police and a fire investigator with Brampton Fire and Emergency Services will be working to determine the cause of the deadly blaze.

Clark said it appears the fire started on the main floor of the residence.

“We are unsure if there were any working smoke alarms. Nevertheless, this should be a reminder to everyone the need to have working smoke alarms and carbon monoxide alarms,” Clark said.

“Fire spreads very rapidly and in this case, three people were trapped in the house.”

Clark called the deadly fire “tragic.”

“We have had other tragedies in the past, but certainly this is touching in the sense that we have lost three lives,” he said.

Grief-stricken neighbours and friends who went to the scene described the family as friendly and sweet.

A friend told The Canadian Press that the 18-year-old daughter was a talented young woman who had just started at the University of Guelph-Humber

“She was really smart and she was really sweet and so was her mom. They were just really nice people,” Nicole Chevolleau said. “I still can't even process it. I was in class when I found out and I left.”
