Canada's Beach Closures
Beach closures and beach water quality advisories in Canada are common during the summer season. Health inspection agencies test the water quality at public beaches in their jurisdiction during the time of year the beach may be used for swimming.
Guidelines for Canadian Recreational Water Quality are the benchmarks for safety. For example, high counts of e. coli bacteria in the water can pose a health issue for people swimming in the water and result in a beach closure. The beach water is generally sampled on a weekly basis although some jurisdictions sample daily.
