An OPP officer injured in a crash near Angus on Wednesday is improving.

The crash happened just before 10 a.m. on a curve along County Road 10 near the 4th Line of Essa when his unmarked cruiser went off the road. Police say it rolled off the road, through a ditch, and hit trees before coming to a stop. The officer had to be pulled from the vehicle by emergency crews.

Ornge airlifted the officer to St. Michael’s hospital in Toronto with serious injuries to the head and chest.

His injuries were considered serious at the time of the accident but he was listed in stable condition on Thursday morning.

It's unclear why he was in the area at the time, or whether he was responding to a call. Police are still investigating.

The OPP would like to thank Essa Fire Department, Simcoe County Paramedics, Ornge Air Ambulance Services and all of the medical staff involved in helping the officer
