A crash involving a dump truck has snarled traffic along the 401 this evening.
Toronto Fire say the call came into them at around 4:30, and when they arrived on scene they found a dump truck on its side, with a load of gravel or sand all over the road.
For some unknown reason, the driver of the truck lost control, striking several vehicles before tipping over and landing on a car, dumping sand into the damaged vehicle.
One man was killed, and three other people were taken to hospital with what paramedics describe as minor injuries.
OPP say that 9 other vehicles were involved in the crash.
Officers closed the eastbound side of the 401, in the express at Avenue road to the Allen, and believe it could be closed until at least 10 PM.
