PFAS 'forever chemicals' contamination raises health concerns in Sault Ste. Marie

Residents of Sault Ste. Marie, Ontario, are alarmed after decades of firefighting‑foam runoff from the local airport introduced per‑ and polyfluoroalkyl substances (PFAS) into the Pointe Des Chênes neighbourhood. Community members such as Peter Gagnon worry that their grandchildren could be exposed to the chemicals, saying, “That's what sort of got this started, thinking about grandkids…going in that water and exposing them to harmful chemicals.” Health Canada links PFAS exposure to reproductive, developmental, endocrine and immune effects, and the International Agency for Research on Cancer labels per‑fluorooctanoic acid as possibly carcinogenic. Authorities advise against eating fish from the creek that feeds the St. Marys River. Similar PFAS contamination has been documented at other Canadian airports, prompting the Department of National Defence to allocate $120 million for cleanup at the North Bay site and spurring class‑action lawsuits seeking up to $100 million in damages for property‑value losses.
