One man is dead after a dump truck turned over onto a car on the 401 eastbound at Avenue Rd., according to Toronto EMS.

Emergency crews are on the scene after the collision, which occurred around 4:45 p.m. on Tuesday afternoon.

The victim was pronounced dead at the scene, after being trapped under the dump truck.

EMS said three more victims in the collision, which involved nine vehicles, sustained injuries that are not considered serious. One of those victims has been taken to the hospital with minor injuries, while two others were transported with non life-threatening injuries.

The dump truck appears to have crushed the car, spilling sand across the road for several metres.

All eastbound express lanes are closed, and traffic is being diverted at Allen Rd., according to Sgt. Kerry Schmidt. The northbound Allen to the 401 ramp will also be closed, pending the OPP investigation.

Police say the highway is not expected to reopen for several hours.
