Dentists want to keep it in, but one group wants communities across Canada to keep fluoride out of the water we drink. A new group, Fluoride Free Canada, is expected to announce a new initiative to make sure fluoride is not added to drinking water in any Canadian community. Details of the announcement have been embargoed until late Wednesday morning, but it comes as the debate continues to take place in some Windsor-Essex communities on whether the anion should be added to the water.
