Dr Marilyn Korzekwa, MD was the first person to have completed Lake Ontario swims from both south-to-north and north-to-south 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 Toronto with the legendary Cliff Lumsdon driving the inflatable.
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) husband Peter, Cliff Lumsdon, and Brian Mercer. At the right, and 23 hours 0 minutes and 23 seconds later, Marilyn is seen exiting the water at the beach to the west of the harbour at Port Dalhousie.
