Founded in 1975, we are a group of passionate volunteers dedicated to safe adventures in our Great Lakes that honour the traditions of marathon swimming. We observe and ratify escorted but unassisted marathon swims in Ontario waters, and we curate a history of swims in our waters that meet these standards.
Swim with us! Tell us about yourself, your swimming, and your planned swim.
Once you've completed these steps, we'll be in touch with you about fees, timing, and logistics. You will need to find boats, a pilot, and crew, but we can help! We'll assign you a swim master who can guide you through these steps, and who will serve as the official observer on your swim. We're a safety organization, so our primary focus will be helping ensure a safe crossing for everyone involved, so we'll ask for some more details in the following forms. Please work with your doctor or medical professional to complete our medical evaluation. We'll also ask you to sign a standard liability disclaimer, and to acknowledge our code of conduct.
For Lake Ontario swims that end in Toronto, there are some additional challenges associated with traversing very busy waters! For these routes, we'll need some additional details to help coordinate your swim with the the harbour authorities.
