The victim “was in the water for an hour,” said Peel Regional Police Const. George Tudos.
She was pulled from the water without vital signs and pronounced dead in hospital.
Emergency crews raced to the boat launch on Front St. S., east of Mississauga Rd., south of the lighthouse at 4:14 p.m. after multiple 911 calls came in for a grey four-door sedan plunging into the Credit River near Snug Harbour restaurant.
Two men reportedly tried to help the victim but the water drifted, carrying the car about 50 feet south, where the Credit River meets Lake Ontario.
“Because of the cold water, they had to get back out,” said Tudos.
“They couldn’t do anything.”
Divers were en route to the call at 4:30 p.m., when the car went underwater.
Firefighters worked with the marine unit and the “occupant was extracted before the car,” said Tudos.
An Ornge air ambulance was sent to the scene, however, Peel Paramedics performed CPR and transported the woman to hospital.
Officers with the 11 Division criminal investigation bureau are working the case.
“I think they have a good idea of what happened but I don’t know if it’s something we’re going to release,” said Tudos.
