A 43 year old Caledonia woman is in hospital with critical injuries after a serious five car pile up on Highway 6 south during yesterday's snowfall.
OPP say four people were taken to hospital after several vehicles veered from the road, with some coming to rest in the ditch.
Three of four drivers suffered minor injuries.
The highway, between Chippewa Road and Leeming Road, was closed until about noon for the police investigation and for cleanup.
It was one of 24 crashes with which the OPP had to deal.
