Orillia OPP is continuing its investigation into a fatal collision that happened in Oro-Medonte last night.
Just before 11 p.m., police and Simcoe County Emergency Services were called to a single-vehicle rollover that happened on Ridge Road between Line 4 and Line 3 South.
Four people were found to have been involved.
One person was taken to hospital, where they were pronounced deceased.
That person has been identified as an 18-year-old man from Barrie.
A second person was taken via Ornge to a Toronto-area trauma centre, where they were said to have serious, life-threatening injuries.
The other two people were taken to a local hospital to be treated for minor injuries.
