Toronto Beach Water Quality

Visit one of Toronto's beaches this summer!

Toronto has some of the best beaches in the world, which is verified by the Blue Flag Program. This internationally recognized program awards blue flags to communities committed to maintaining high standards for water quality.

From June to Labour Day, the City of Toronto takes daily water samples from the supervised beaches across the city and tests for E. coli bacteria. When E. coli levels are high Toronto Public Health posts warning signs against swimming. Find out more about testing.

For Lake Ontario Surface Water Temperature, take a look at the National Oceanic and Atmospheric Administration (NOAA) forecast.

Alert: Heavy rains and high water levels in Lake Ontario may have created beach conditions which are unsafe for swimming. Please click on the following link for current information on beach conditions.

Lake Ontario water levels are at a record high and have impacted safety conditions at many of Toronto's beaches. The affected beaches may not be open or may have limited lifeguard supervision. For more information visit the Parks Forestry and Recreation division's beaches web page.

Swimming conditions as of: September 2, 2019

The public should not swim during and after storms, floods, or heavy rainfall. Cloudy water can be an indicator of high levels of bacteria that may pose a risk to human health.

Conditions are based upon E. coli counts in beach water samples taken over the past 24 hours.
