Three people were rushed to hospital Tuesday afternoon following a two-vehicle collision in Mitchell.
At 1:50pm, the Perth County OPP responded to the crash at the corner of Montreal St. and St. David's St.
Police say a sedan was travelling east on Montreal St. when it collided with a large van travelling south on St. David's St. The sedan came to rest near a house.
The 81-year-old woman who was driving the sedan was taken to a local hospital and later airlifted to a London hospital with life threatening injuries.
There were four occupants in the van; two were taken to hospital with non-life threatening injuries.
No names have been released.
