I can certainly respond on behalf of....
Indeed, there was a recent report that published the scientific findings of the class of per- and polyfluorinated alkyl substances. Based on that assessment, it determined there was a subclass for which there was a certain amount of uncertainty on both the health and environmental effects of that subclass within that broader class of PFAS chemicals.
There's a certain threshold by which it is determined under the Canadian Environmental Protection Act to take regulatory action on this class of chemicals. It was felt that further analysis was required on that subclass prior to making a full scientific determination.
In terms of a path forward, there has been a commitment to add fluoropolymers to the plan of priorities, which is a requirement under the Canadian Environmental Protection Act. There is a commitment to undertake an assessment in the near future of that subclass of fluoropolymers to determine whether or not they do have any health or environmental effects.
