Rees Street Slip


This slip represents the hub for recreational water use in the inner harbour. It is the home of the Harbourfront Nautical Centre, where they offer lessons for canoeing, kayaking, sailing, and powerboating. Lessons are available for beginners and enthusiasts of all skill levels and physical abilities. There is also opportunity to rent boats from this location.

A combined sewer outfall is located here, stretching out from the centre of the slip. Five different sites are sampled in this slip, and the geomean of those six sites determine the water quality.

MONITORING FREQUENCY

Rees Street Slip is sampled weekly from May 1st to September 30th

SOURCE INFORMATION

Lake Ontario Waterkeeper staff, interns and volunteers monitor freshwater quality at the Toronto Inner Harbour year round, even outside of summer months. According to the province’s Beach Management Protocol, official sampling season starts June 1st and ends September 30th. This coincides with the official swim season in Ontario.

Samples are collected on a weekly basis, every Wednesday morning. Water is sampled for E. coli and Total coliform at all sites. Beaches in Ontario are posted when the geometric mean of 5 samples collected within a given swimming area and within a 30-day period exceeds 100 E.coli / 100 ml of water. A Ministry of the Environment procedure says that a clean beach meets water quality criteria at least 95% of the swimming season, even if it is near a sewage pipe.

Test results are expressed as Most Probable Number (MPN) of E.coli cfu (colony forming units) per 100 ml by using the IDEXX Quanti-Tray/2000 MPN Table.

A beach is marked Green when geometric mean of 5 samples results are equal or below 100 E.coli / 100 ML water.

A beach is marked Red when the geometric mean concentration (minimum of five samples) is equal to or above 100 E.coli / 100 ML water, according to Ontario’s water quality guidelines.

A beach is marked Grey when there are no current results or there is no available information.

Results are posted as soon as lab results are available. Results will be communicated through the swim guide app.
