Lake Ontario, 1983 & 1984

Marilyn Korzekwa, MD was the first person to have completed Lake Ontario swims from both south-to-north and north-to-south directions on September 1-2, 1983 and August 17-18, 1984 respectively. Her 1984 north-south swim was the first completed by a Canadian, and had only been preceded by USA swimmer Diana Nyad in 1974.

The start of the 1983 swim is shown above, together with the approach to Leslie Street Spit (Toronto) with the legendary Cliff Lumsdon driving the inflatable. There was a strong northerly head wind that slowed Marilyn down and hurt her shoulders.

The start and finish of the 1984 swim are depicted below. On the left and about to exit the inflatable to start at Leslie Street Spit, Marilyn is seen well-greased with (L-R) friend, Cliff Lumsdon, and Brian Mercer. At the right, and 21 hours 0 minutes later, Marilyn is seen exiting the water at Lakeside Beach in Port Dalhousie. She was caught in the current exiting from the Port Dalhousie Harbour and had to sprint to get through it to the beach.
