A 49-year-old woman from Toronto was killed in a Christmas Day crash in Springwater Township.
The crash happened on County Road 53 between Carson and Sunnidale Roads, northeast of Barrie.
The deceased was in a car with two other people. They were taken to hospital with critical injuries, but their conditions have since improved.
A child and two adults in the second vehicle had only minor injuries.
