Toronto Outer Harbour

Toronto, Ontario

Toronto's Outer Harbour boasts a unique view of the city and is home to many recreational water clubs, such as: Toronto Windsurfing Club, Water Rats Sailing Club, Mooredale Sailing Club, St. James Town Sailing Club, Outer Harbour Centreboard Club, Hanlan's Boat Club, Westwood Sailing Club, and Toronto Multihull Cruising Club.

In July 2017, the Outer Harbour Sailing Federation collaboratively initiated a sampling program with Lake Ontario Waterkeeper (LOW) as part of LOW's pilot project to support external samplers in their efforts to obtain accurate and up-to-date water quality information in areas with no official monitoring. Samples are collected on a weekly basis by boat.

The water samples are then processed and analyzed at Lake Ontario Waterkeeper's in-house lab. Sampling and analysis are done in adherence to Ontario's Recreational Water Protocol, 2014.

SOURCE INFORMATION

During the 2017 summer season, until the end of August 2017, Lake Ontario Waterkeeper is running a pilot program to support external samplers in their efforts to obtain accurate and up-to-date water quality information for recreational water sites that are currently unmonitored areas by the City of Toronto.

Water quality information is much needed for these sites due to water quality concerns (e.g. may be affected by sewage pollution) and to their popularity among recreational water users. A small team of citizen scientists is conducting water sampling on a weekly, volunteer basis. These external samplers have been trained by Lake Ontario Waterkeeper staff. The water samples are processed and analyzed at Lake Ontario Waterkeeper's in-house lab. Sample collection and analysis are done in adherence to Ontario's Recreational Water Protocol, 2014.

Samples are collected on a weekly basis, every Tuesday evening (Outer Harbour) or Wednesday morning (Humber Bay Park West). 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. To see a full sample results tables visit the Lake Ontario Waterkeeper website. Results are also available by email at contact@theswimguide.org or by calling The Swim Guide +1 (416) 861-1237.
