Road closures

The Toronto Waterfront Marathon has more road closures than any event in the city, but fortunately for people making their way around downtown, many of them will be lifted by late Sunday afternoon.

Key areas of the run will, however, be closed from Saturday to Sunday evening. The chart below offers an overview of all the closures.

For more detailed information consult the official Toronto Waterfront Marathon website. There's also an interactive map that some might find useful for tracking participants and charting road closures.
