Ontario citizens are commonly told that the fluoride product used in drinking water is “safe and effective” but what they are not being told is that the fluoride being bandied as "safe and effective" is either a silicofluoride such as sodium hexafluorosilicic (or one of its synonyms) or hydrofluorosilicic acid (or one of its synonyms). What Canadians do not know is that these silicofluoride substances used in tap water fluoridation are not safe based on

a) standard scientific evidence, and
b) legal requirements in Ontario and 9 out of 13 provinces and territories in Canada.

The scientific and legal determination of safety is based on 2 types of research:

1. Animal studies (toxicology studies), and
2. Human studies (clinical trials).

Health Canada, provincial government agencies, professional engineers in charge of water utilities (OROs in Ontario), and municipalities across Canada know, or should know, that the actual fluoride products used in artificial water fluoridation (silicofluorides: H₂SiF₆, Na₂SiF₆) have been used for over 40 years with neither the required animal studies (toxicology studies) nor the required human studies (randomized controlled clinical trials) to determine safety in order to protect consumer safety and satisfy the legal requirements in Canada.

Health Canada, provincial government agencies, professional engineers in charge of water utilities, and municipalities across Canada know, or should know, that hydrofluorosilicic acid is an unregulated, unapproved medication, as stated clearly by Health Canada as follows:

•  HEALTH CANADA states the following in Petition #299 (Answer #3) to the Auditor General of Canada: “Health Canada does not regulate hexafluorosilicic acid or sodium silicofluoride products, the actual products used in water fluoridation, which are allegedly used as a medical treatment to prevent dental disease.”

•  Health Canada, provincial government agencies, professional engineers in charge of water utilities (OROs in Ontario), and municipalities across Canada cannot make valid claims of treating and preventing tooth decay while promoting a product (hydrofluorosilicic acid) that has never been approved for such claims for either topical applications through oral exposure, systemic effects through ingestion, or trans-dermal exposures through the skin while bathing and showering. This has been done without our consent and without conducting the appropriate evaluation processes and approvals.

Health Canada, provincial government agencies and municipalities across Canada know, or should know, that any claims of safety for the fluoride products used in drinking water are not based on standard scientific protocols or the legal requirements in Canada.

"The evidence that fluoridation is more harmful than beneficial is now overwhelming and policy makers who avoid thoroughly reviewing recent data do so at risk of future litigation." Dr. Hardy Limeback, DDS, PhD.
