The public was asked to stay away from the Sarnia Bay area for an incident, which has since been resolved.
There was an increased police presence in the area as they, Lambton EMS and Sarnia Fire and Rescue, dealt with a person in crisis.
Police received the initial call of a person in crisis driving a car at the water's edge around 5:50 p.m.
