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.
