Hamilton Public Health Services monitors the recreational water quality at public beaches each year for levels of E. coli bacteria and Blue-Green Algae (cyanobacteria). 

Public Health Services monitors beaches annually from the beginning of June until the end of August.

Beach water quality testing

Public Health services monitors beaches in accordance with the Ministry of Health and Long-Term Care’s Operational Approaches for Recreational Water Guideline 2018 and the Recreational Water Protocol 2018 under the Ontario Public Health Standards. As outlined in the above protocols, beach samples are collected and tested for E. coli bacteria during the swimming season.  Note: The sampling frequency of Lake Ontario beaches has been reduced to once per month due to a history of water quality consistently testing below the threshold for posting a beach and in accordance with the Recreational Water Protocol, 2018.

Beach sampling results cannot be guaranteed accurate as conditions can change quickly depending on the weather. You should not swim at the beach during and after storms, floods or heavy rainfall. Cloudy water may indicate high levels of bacteria.

For more information on ways to stay safe at the beach, visit the Canadian Red Cross’s website. 

To report safety hazards at the beach please call 905-546-2489.

Beach water quality test results

High numbers of E. coli in the water at public beaches indicates contamination with feces and the potential presence of other harmful microorganisms in the water. The provincial standard is 200 E. coli bacteria cells per 100 ml of water or 200 colony forming units per 100 ml.  

E. coli concentrations at or above the standard could cause an increased risk of infection. Swimming in these waters could cause infections in ears, eyes, nose, throat and skin as well as cause diarrhea if the water is ingested.
