Provincial police say one person is dead and five others have been taken to hospital following a multi-vehicle crash on the 402 in London.
They say those sent to hospital all suffered non-life threatening injuries.
OPP say the collision involved two tractor-trailers and two motor vehicles which all were travelling eastbound on the highway.
The cause of the collision remains under investigation.
But police believe an inattentive truck driver, led to a pile up on the 400 north of Toronto last Friday night, that left four people dead.
They say the crash was “absolutely preventable.”
Sgt. Kerry Schmidt says investigators are still trying to identify some of those killed in the 11-vehicle collision _ but one is believed to be a four-year-old girl.
That crash involved three transport trucks along with several other vehicles and one of the trailers and two vehicles caught fire.
Schmidt says the highway surface had to be ground down because molten metal from the fire was protruding from the asphalt.
