A 3-year-old child is fighting for their life following a three-vehicle crash on Highway 401 on Friday night.
Provincial police say the crash happened in the westbound express lanes of the 401 near Warden Avenue around 10 p.m.
Sgt. Kerry Schmidt says the lead vehicle in the chain reaction crash was slowing down and coming to a stop due to traffic when it was struck by a small Honda containing a family of four including two children. That car was then struck by a pick-up truck.
A 3-year-old was transported to a trauma centre with life-threatening injuries while a 6-year-old suffered critical injuries.
Three other adults were also injured in the crash. One woman suffered serious injuries while two others suffered minor injuries.
Police say there is currently no indication of drug or alcohol use being a factor in the crash with signs pointing to driver inattention or drivers not responding to changing traffic patterns as the cause.
