OTTAWA — Nearly a year after Health Canada issued a draft recommendation to designate an entire class of chemicals as toxic, environmental experts say it's time to actually do something about it.
Cassie Barker, the toxics program manager at Environmental Defence, told the House of Commons environment committee Thursday that the chemicals have one of the strongest bonds in organic chemistry, making it nearly impossible for them to break down. In May 2023 Health Canada issued a draft recommendation, following a scientific review of available evidence, that said the science meets the requirement to label PFAS as toxic under the Canadian Environmental Protection Act.Barker said not only is it time to move to finalize that designation, the regulations must swiftly follow. She said the important thing is to designate the entire class, not just each substance individually.
California has put limits on the use of the chemicals in food packaging, banned them entirely in products aimed at children under the age of 12 and will ban all PFAS from cosmetics next year. The chemicals were unregulated at that point. DuPont also paid more than US$107 million to settle a water-contamination lawsuit by residents who lived near the West Virginia plant.
Barker said even if there are limits placed on PFAS in drinking water, municipalities are at a loss about how to comply. The technology that would at least capture most of the chemicals is extremely expensive, she said, and municipalities have no power to keep them from entering their waterways in the first place.
