Police in Tobermory, Ontario, Canada, pulled a red car from the harbour early on Friday morning after a woman followed instructions from her GPS and drove down a boat launch ramp and into the water.
Ontario Provincial Police said the woman was following her GPS "when she took a wrong turn into Little Tub Harbour" late on Thursday night.
It was raining, dark and foggy at the time.
Combining "weather conditions and the driver being new to the area, a fully submerged vehicle was the result," police said.
The 23-year-old Kitchener woman was able to roll down her window, get out of the submerged car and swim approximately 30 metres to shore in 4°C water.
She then called for help.
Except for being cold and wet, the woman was unhurt.
A tow truck was able to pull the submerged car out of the harbour at 8:22am on Friday morning.
