Marina Four


Marina Four is a well-protected slip that sits between Rees St. and Lower Simcoe St., right in the heart of the Harbourfront Centre. It is adjacent to the Concert Stage, and under the Amsterdam pedestrian bridge. While not a popular swimming location, it is extensively used by boaters many of whom call the marina home. The City of Toronto does not monitor here.

A combined sewer outfall is located in the northeast corner of the marina. Swim Drink Fish staff along with trained citizens scientists monitor this location once a week, on Wednesdays. New results are posted to Swim Guide on Thursday afternoons until the end of September. These citizen scientists are a part of the Toronto Monitoring Hub, which is one of Swim Drink Fish’s monitoring hubs. You can access the detailed open data files for this location here:
