Toronto Beach Water Quality
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.
