A 38-year-old mother and her five-year-old son are dead after they were found without vital signs in a Brampton backyard pool Saturday evening, Peel police say.

The pair were rushed to hospital, where they pronounced dead, according to Insp. Bill Ford, duty inspector for the Peel Regional Police.

Autopsies will be performed on the bodies in the next few days to determine the cause of death, police said.

On Saturday at about 8 p.m., emergency crews were called to a home in the Airport Road and Countryside Drive area after receiving reports of two people unresponsive in the water.

Peel police said they were called to the scene for "medical assistance."
