One person is dead after a collision on the westbound QEW early Tuesday morning.
The collision between a car and a transport truck happened just past Walkers Line in Burlington, just after 2:30.
The person inside the car was pronounced dead at the scene.
OPP say the province's Special Investigations Unit has invoked their mandate.
The SIU is an arm’s length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
All lanes of the westbound QEW are closed at Walkers Line. You can re-enter the QEW at Guelph Line.
