Toronto Outer Harbour - Bay

Toronto, Ontario

Toronto's Outer Harbour boasts a unique view of the Toronto Skyline, 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.

The waters of Lake Ontario in Outer Bay of Cherry Beach are tested, as this is the location of many sailing, rowing, and kitesurfing races. Daily from the month of May to the end of October you will see many sail boats, kite surfers, wind surfers, and rowing boats out on this part of Lake Ontario.

MONITORING FREQUENCY

Toronto Outer Harbour - Bay is sampled weekly from June 20th to August 7th

SOURCE INFORMATION

For the 2018 summer, the Outer Harbour Sailing Federation initiated a community sampling program in collaboration with Swim Drink Fish Canada. This is part Toronto Community Monitoring Program supporting recreational water communities in their efforts to obtain accurate and up-to-date water quality information in areas with no official monitoring.

Trained community members monitor recreational water quality at two locations in the Outer Harbour of Toronto, ON during the summer months. The standards followed are Ontario’s Provincial Water Quality Objectives, set by the Ministry of Environment and Climate Change at 100 E.coli per 100 millilitres of water.

Water is sampled for E. coli and Total coliform at all sites. Sampling occurs once a week on Wednesday afternoon from the June 20th to September 30th, 2018. Results are available 24 hours after samples are collected, on Thursday evening.

Beaches 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 or combined sewer outfall.

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 website and apps.
