I can say that, under the Canadian Environmental Protection Act, there is a list of chemicals, an inventory of chemicals, that are permitted in Canada, whether they be private entities or federal jurisdictions that are allowed to be using those. Anything that's not on that list would have to be notified to both Environment and Climate Change Canada and Health Canada before their market access.
There is a well-defined list of chemicals that are currently used in Canadian commerce, including at DND bases. Those are actively being assessed, both at Environment and Climate Change Canada and Health Canada, for the risks.
