Who watches the fluoride levels in the drinking water?
Health Canada, through a joint federal/provincial committee, is responsible for watching the level of fluoridation in water supplies. In recent years, this committee has recommended that optimal levels of fluoride should be between 0.8 and 1.0 parts per million. This recommendation is based on the fact that many Canadians receive fluoride from many sources. As a result, some communities have lowered the level of fluoride in their water supply, in keeping with this recommendation.
