The TCS Toronto Waterfront Marathon is Canada’s premier running event and the grand finale of the Canada Running Series. Since 2017, the race has served as the Athletics Canada National Marathon Championships and has doubled as the Olympic Trials.

With innovation and organization as our guiding principles, we stage great experiences for runners of all levels, from Canadian Olympians to recreational and charity runners. Our mission is “building community through the sport of running” and we are committed to making sport part of sustainable communities and the city-building process.
