So, yes, I think we knew before that.
Bagotville, of course, is the site of airfields, but it's also a firefighter training area. I'm talking about PFAS here, in particular. PFAS is a contaminant found in firefighting foam. As a result of that, we identified PFAS contaminants across the country, including in Bagotville. We have been, since 2010, regularly testing for PFAS across all of our sites. I don't know exactly when we found it.
I might invite Mr. Sattar, if he knows the exact date, but we would have identified it before 2022.
