Thank you very much.
I hate to beat a horse, but I am very interested in this topic of PFAS as well.
In my riding of Aurora—Oak Ridges—Richmond Hill, there is an organization called the York Region Environmental Alliance, which has done a lot of work on this. Of course, the firefighters for both York and Richmond Hill have as well. I've met with them and talked about this.
You just said that a lot of the firefighting foams are alternatives now. There is something available. What are the essential uses or projects that we have to continue to allow these chemicals to be put into? Which ones are absolutely essential?
