BC having almost no fluoride additive water is literally my favourite factoid to bring up whenever I run into conspiracy thoerists spouting nonsense about government controls of populations using fluoride
Actually, it's not widely used Canada-wide, first number is percentage of the population that's drinking water with fluoride... second number is percentage that is drinking water with no fluoride in it:
British Columbia 1.17% 98.83%
Alberta 42.43% 57.57%
Saskatchewan 39.6% 60.4%
Manitoba 69.01% 30.99%
Ontario 71.1% 28.9%
Quebec 2.49% 97.51%
New Brunswick 1.18% 98.82%
Nova Scotia 46.91% 53.09%
Prince Edward Island 24.20% 75.80%
Newfoundland/Labrador 1.46% 98.54%
Nunavut 28.83% 71.17%
Northwest Territories 64.91% 35.09%
Yukon 0% 100.00%
Canada as a whole 38.7% of water supply has fluoride, 61.3% does not.
This is from 2017 statistics, Alberta's numbers would obviously sway if Calgary jumped on the fluoride wagon. Only Ontario, Manitoba and NWT are heavy fluoride users.
