Toronto Waterfront Marathon, live.

Downtown and along the waterfront in October

The TCS Toronto Waterfront Marathon weekend is on 16 and 17 October 2027, with the marathon and half marathon on Sunday morning and a 5K on Saturday.

Part of the Canada Running Series, the 2027 TCS Toronto Waterfront Marathon is on Sunday 17 October, and registration is open. The marathon and the half marathon both start at 8:00 on Sunday, and the 5K starts at 9:00 on Saturday 16 October.

In 2026 the 42K and 21K started on Yonge Street north of Gerrard, facing north, and finished on Bay Street just north of Queen Street. Race Central at Nathan Phillips Square holds bag check, food, water and the help desk for participants and their families. The marathon course runs through the downtown core and along the waterfront of Toronto, through more than a dozen neighbourhoods, with aid stations about every 3 km.

The marathon has a six hour time limit and the half marathon three hours and thirty minutes, and both start in corrals by expected finish time. The 5K starts on Bay Street north of Front Street and finishes on Bay Street north of Queen, and its awards ceremony is on the main stage at Nathan Phillips Square.

Race kit pickup and the expo are at the Better Living Centre, where a Speaker Series runs during the weekend. Participants in the 5K must collect their bib on the Friday, as there is no race day pickup.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, and the official results come from the Canada Running Series.
