A 24-year-old London, Ont., man has become the youngest person to swim across Lake Huron.

Justin Kloss entered the water in Port Sanilac, Michigan on Friday morning to start the 65-kilometre journey.

He reached the shore in Grand Bend, Ont., just before noon today. Money raised from the charity swim will go to the Canadian Cancer Society.

Kloss isn't the first member of his family to swim from one side of Lake Huron to the other.

His grandfather became the oldest person to swim across the lake 20 years ago, when he was 50.

Another London man, Greg Willoughby, is expected to finish his swim across Lake Ontario today. He is raising funds for a mental health centre.
