Grey Bruce OPP say one person has died after a serious collision just outside of Wiarton.
South Bruce Peninsula firefighters, Grey County paramedics and Grey Bruce OPP responded to the single vehicle incident along Concession 21 just before 2:30 p.m. Tuesday afternoon.
The OPP say a 69-year-old from Neyaashiinigmiing was pronounced dead after being transported to hospital.
Three other people were also taken to hospital for treatment of injuries police describe as non-life threatening.
The fatal accident closed Concession 21 between Zion Church Road and Sideroad 20 for several hours yesterday, but it has since reopened.
