What Canadian Cities Add Fluoride to their Drinking Water?

In review (from Canadian Dental Association)

Ontario, Alberta and Manitoba have the highest percentage of community water fluoridation with rates of 75.9%, 74.7% and 69.9% respectively. At the other end of the scale, the lowest rates of water fluoridation can be found in British Columbia (3.7%), Newfoundland and Labrador (1.5%) and Nunavut and the Yukon (0%)

In Canada, the government recommended level of fluoride in the tap water is 0.7 milligrams per litre (mg/L). This is equal to 3 drops of water in a 55-gallon barrel.

The maximum acceptable concentration in the Canadian Guidelines for fluoride in drinking water is 1.5 mg/L. Whether naturally occurring or added during the water treatment process, fluoride levels should never exceed this level.

To find out if Fluoride is added to your tap water or if naturally occurring fluoride exists in your drinking water, contact your local government*, or have your water tested.
