Two parents and three children killed in a Brampton, Ont. house fire early Monday morning have been identified by friends and family.

Peel Regional Police said emergency crews were called to a home on Conestoga Drive, near Sutter Avenue, in the Kennedy Road and Sandalwood Parkway East area, just before 2 a.m. for reports of a fire.

Crews were able to pull four people from the house, but all were later pronounced dead. A fifth victim was located deceased inside the home during a search.

Rescuers found a sixth adult victim outside the home who got out on their own and was rushed to Sunnybrook Hospital for treatment of critical injuries.

The children's father, Nazir Ali, and mother, Raven Ali-O'Dea, were killed in the blaze, family and friends told CP24.

Their three children, Alia, 10, Jayden, eight, and Layla, seven, were are also killed.

"This is unbelievable," Ali-O’Dea's father, Louie Felipa, said Monday at the scene. "This pain I'm going to carry for the rest of my life. I don’t know what I’m going to do."

He suggested the family did not have working smoke alarms in the home.

"My aim today is to make sure people know how important it is to have a smoke alarm," he said. "This pain, I don’t want anyone to go through it."

The fire in the home raged for several hours, and the Fire Marshal was called in to investigate what caused the blaze.

The City of Brampton said it would lower flags at all municipal facilities to half-mast today to mourn the loss.

"I just can't imagine the hurt being felt by the family, the friends and the community. You'll all be in our prayers," he said during an unrelated announcement in Brampton on Monday

Prime Minister Justin Trudeau, who was with Ford, said his thoughts were with the family and friends of those who died.

"We're all thinking of those affected by this horrible, heartbreaking tragic fire," he said.
