Single Year Data Tables By Facility – Releases, Transfers And Disposals

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling.

Each file contains facility-reported data listed by facility and substance for a given year. Data are presented in a table and can be filtered.

Please consult the following resources to enhance your analysis:
