The Sarnia Police Service (SPS) continue to investigate a crash that happened Sunday.
Emergency crews responded at 2:20 p.m. to the intersection of Confederation Street and Indian Road for a single-vehicle collision.
Emergency first aid was provided to a 68-year-old woman who had seemingly suffered a medical incident while driving.
The woman, who was the only occupant of the vehicle, was taken to hospital. No serious injuries were sustained as a result of the crash.
SPS determined that the woman's medical emergency caused her to veer off the road and hit a hydro box, causing a power outage for a small portion of the city.
Bluewater Power resolved the outage quickly.
Police closed the area to traffic for the preliminary investigation, it has since been reopened.
