Sunnyside

Toronto, Ontario

Opened in the roaring 1920s, Sunnyside Beach was the place Torontonians came to play for decades. This waterfront icon played host to bathers, concerts, tightrope-walkers and even an amusement park. The Palais Royale was one of Toronto’s most popular dance halls, featuring jazz greats like Duke Ellington and Count Basie. In 1954, sixteen-year old Marilyn Bell ended her historic first swim across Lake Ontario nearby. Not long after that, the Gardiner Expressway went up and the amusement park came down. Today, you can still use the Sunnyside Bathing Pavilion and swim in the pool (aka, “The Tank”), have drinks and a bite to eat on a patio overlooking the beach, and of course, have a splash in Lake Ontario.

SOURCE INFORMATION

Toronto Public Health samples water quality on a daily basis from early June until Labour Day. Swim Guide updates Toronto beaches using the City of Toronto's Open Data.

The official swim season in Ontario is June 1 - September 30.

Ontario beaches are monitored according to the province's Beach Management Protocol. Municipal health authorities monitor most public beaches. Provincial park beaches are monitored by Ontario Parks. The Protocol says that authorities must check water quality at least weekly from June 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!
