The good news, fortunately, is that the situation is much less serious in Canada than in the United States with respect to perfluorinated compounds. The main reason is that Canada has never produced these compounds.
In the United States, new regulations will affect 67 million Americans—I've never seen anything like it in my career. It will certainly cost a lot of money.
Does that mean everything is fine in Canada and we can ignore the problem? Unfortunately, the answer is no. The whole Great Lakes system is affected, as is the St. Lawrence River, where concentrations of PFAS are below what is permitted by the current proposed figures. And yet we know that these figures should be even lower and that they will eventually have to be reduced. At the moment, conditions in the St. Lawrence are not ideal compared to the proposed standards. If consideration ever had to be given to treating the water in the St. Lawrence, it must not be forgotten that 45% of Quebec's population gets its water from the river. It would have to be done all the way to the Great Lakes, because they are affected as well.
