An accident on Highway 401 at Highway 403 has left one woman dead and another person in critical condition.
It happened around 9 a.m. in the eastbound lanes of the 401 express and both victims were airlifted to hospital a short time later.
According to Peel Police, it was a vehicle rollover and Highway 401 express is now closed on the eastbound side just west of Pearson International Airport.
A 61-year-old man was transported to a nearby hospital initially with serious injuries. His condition has now been downgraded to minor.
Ontario Provincial Police are now at the scene investigating trying to determine the cause of the accident.
Police believe a second vehicle, a dark coloured SUV, may have been involved in the incident.
