Following a public referendum in 2010, the Region of Waterloo, Ontario, ceased adding fluoride to its municipal water supply. This decision is often a point of confusion for residents, as the answer to 'Does Waterloo have fluoride in the water?' depends on the specific location and source of water in question, including the tap versus bottled sparkling water.

According to the Region of Waterloo, 75 to 80 percent of the area's drinking water comes from groundwater, and the remainder from the Grand River. This blend of sources is rigorously treated and tested, confirming that Waterloo water is drinkable and meets all health-related Ontario Drinking Water Standards.
