Date change is due to the current situation with the global coronavirus (COVID-19) pandemic.

The National Pollutant Release Inventory (NPRI) has the Single Window NPRI module, which was launched March 12, 2020, is currently available at

The NPRI is Canada’s inventory database of pollutants released to the air, water and land.

It is managed by Environment and Climate Change Canada.

Anyone can access the inventory. It includes information that is useful for governments, researchers, the media and the public.

The National Pollutant Release Inventory is designed to disclose emissions from all facilities across Canada and is tracked in a database of emitters.

Three main factors that determine if your facility has to submit an NPRI report:

  1. The activities that take place at your facility
  2. The total number of hours worked at your facility
  3. The substances manufactured, processed, otherwise used, or released to the environment at your facility

There are minimum requirements which including the number of hours worked during any one month, as well as minimum reportable quantities.

To find out if the NPRI requirements apply to your facility, ask yourself the following questions:

  1. Do any of the following activities take place at my facility?
    • pit or quarry operations
    • wood preservation
    • fuel terminal operations
    • municipal wastewater collection and/or treatment
    • operation of stationary combustion equipment
    • waste or sewage sludge incineration
  2. Do employees and contractors work more than 20,000 hours during a year (about 10 full-time workers)?

If you answer yes to either or both of the above questions, you may have to submit an NPRI report if you can also answer yes to the following question:

  • does my facility manufacture, process, otherwise use, or release, one or more of the NPRI substances and is the quantity above the threshold for that substance?

If you answer no to all of these questions, you may not have to submit an NPRI report.

The NPRI inventory includes pollutants that were disposed of or recycled and tracks over 300 substances.
