How much fluoride is in sudbury on Canada city water?

As of my last knowledge update in October 2023, Sudbury, Ontario, does not add fluoride to its municipal drinking water supply. The fluoride levels in the water can vary naturally, but the city primarily relies on naturally occurring fluoride, which is typically at low levels. For the most current information, it's best to consult the City of Greater Sudbury's official website or local water quality reports.
