A fundraiser to protect our Ottawa River

The Riverkeeper 4K open water swim is a unique, inter-provincial swimming event in the Ottawa River. Uniting both provincial shores of our river, the swim highlights the need for collaboration towards swimmable, drinkable, fishable waters! Part of the Global Swim Series, this year's swim will feature three distances: 4km, 1.5km, and 750m.

Tom Anzai - In Memory We Swim

Tom was the founder and race director of our annual Riverkeeper 4K swim. He had a vision to swim from one shore of the historic Ottawa River to the other, swam it, then invited all fellow swimmers to participate in what he called an epic charity event. His passion for the event was contagious. He didn’t miss an opportunity to speak not only of the swim, but also of the importance of a healthy Ottawa River. Tom exemplified dedication and community service. We will remember him fondly.
