Ontario Ministry of the Environment, Conservation and Parks Overview of PFAS (September 14, 2021)
-
- Interim drinking water advice recommending that the combined level of 11 specific PFAS compounds in drinking water should not exceed 70 nanograms per litre (ng/L)
Health Canada Objective for Canadian Drinking Water Quality for PFAS (August 9, 2024)
-
- Updated Objective sets a “precautionary group-based” threshold of 30 ng/L for the sum of 25 specific PFAS, replacing previous drinking water guidelines that set screening values for only 9 individual PFAS
- Updated Objective states that PFAS concentrations in drinking water should be maintained “as low as reasonably achievable”

Health Canada and Environment and Climate Change Canada Final State of PFAS Report (March 5, 2025)
-
- Report recommends designating PFAS, excluding fluoropolymers, as “toxic” under Part 2 of Schedule 1 of the Canadian Environmental Protection Act, 1999
- Report notes that many PFAS contaminated federal sites are in areas where local communities rely on private groundwater wells for drinking water
- Report states that despite PFAS being ubiquitous in the environment, certain locations—particularly sites where PFAS has been used, such as firefighting training areas—are considered “hot spots” where elevated PFAS levels may be present
- Report identifies the consumption of drinking water contaminated by PFAS migrating from impacted sites as a key pathway for human exposure to PFAS
- Report states that PFAS are difficult to remediate from contaminated sites and cannot be fully removed from the broader environment
- Report states that “people living in the vicinity of sites contaminated with PFAS (for example associated with the use of AFFF) may also be disproportionately exposed to higher levels of PFAS”
- Report highlights several key concerns regarding PFAS and human health, including significant health impacts linked to PFAS exposure, health effects at lower PFAS concentrations than previously understood, and impacts of bioaccumulation and long-term persistence of PFAS in the human body
