Source Information


The Niagara Region Public Health Services samples beaches weekly from Victoria Day to Labour Day When the information is posted on the Niagara Region Public Health Services website, Lake Ontario Waterkeeper updates Swim Guide.

Ontario beaches are monitored according to the province's Beach Management Protocol. The Protocol says that authorities must check water quality at least weekly from June 1 to Labour Day at beaches where there are formal swimming programs or lifeguards. Most municipalities do not actually begin sampling until mid June. Beaches in Ontario are posted when the geometric mean of 5 samples collected within a 30-day period exceeds 100 E. coli / 100 ml of water.

A Ministry of the Environment procedure says that a clean beach is open at least 95% of the swimming season, even if it is near a sewage pipe. This rule applies to every place that is public, accessible, and feels like a good place to swim. When all else fails, the Ontario Environmental Protection Act strongly states that no one can interfere with the use that you can make of a public waterway - like swimming!
