The woman pulled from a submerged car in Port Credit has died in hospital Monday evening after being inside the vehicle for more than hour.

Peel Regional Police confirmed the woman's death on Twitter. Her identity has not yet been made public.

The female victim was believed to be in her 70s. She was being treated at Trillium Health Centre in Mississauga.

Earlier in the day, Peel Regional Paramedic Services said the woman was pulled from the vehicle at 5:35 p.m. with vital signs absent. They confirmed she was the lone occupant inside a car that went into the cold water where the Credit River meets Lake Ontario.

Peel Regional Police received a call at around 4:15 p.m. about a vehicle that went into the Credit River near Stavebank and Lakeshore roads in Mississauga.

"Some people did try to assist before EMS did arrive," Const. George Tudos said. He told CBC News that some witnesses reportedly swam into the frigid water to try and save anyone who may have been inside the car.

Tudos said he could not confirm how the vehicle ended up in the water.
