One person was airlifted to hospital in a single-vehicle crash late Wednesday night.
Lambton OPP said the crash happened at around 10:45 p.m. on Bentpath Line in Dawn-Euphemia Township.
Police said one occupant sustained serious injuries and was transported to hospital by Ornge air ambulance. A second occupant was also transported to hospital.
Bentpath Line was closed to traffic between Marthaville Road and Tramway Road. The roadway reopened Thursday afternoon after hydro crews repaired equipment and restored power to the area.
The collision is still under investigation.
