Toxic "forever chemicals" are being found in the blood of Canadians — and even higher levels are being found in northern Indigenous communities — says a new report from the government of Canada. Health Canada and Environment Canada have released a draft assessment of the science on per- and polyfluoroalkyl substances (PFAS). Both departments propose listing the human-made chemicals as toxic under the Canadian Environmental Protection Act (CEPA). Canadians have until mid-July to weigh in on the proposed change.
