Please provide a link to a Canadian municipality that has natural fluoride in the water. Through my own research spanning 17 years I have found no natural fluoride present in Canadian municipal water supplies. While its true natural fluoride can be found in some lakes streams and rivers, to date no municipality draws water from any of those water sources which contain natural fluoride.

Heres a primer on water fluoridation.
