The National Pollutant Release Inventory (NPRI) reporting deadline for the 2021 calendar year is June 1st, 2022. The NPRI reporting program is managed by Environment and Climate Change Canada (ECCC) and tracks data on the amount of pollutants released from Canadian industrial facilities into the environment. All levels of government, companies, organizations, researchers, and citizens can use the data to help make informed decisions on protecting the environment and developing pollution management plans.


NPRI reporting is mandatory under the Canadian Environmental Protection Act, 1999.  Facilities will need to report if they meet at least one of the following conditions:

  • The facility’s employees work more than 20,000 hours (about 10 full-time employees) per year;
  • Specific activities (such as incineration, wood preservation, wastewater treatment or fuel combustion) take place at the facility; and/or
  • The facility manufactures, processes, uses or releases NPRI substances above reporting thresholds.

Owners and operators of facilities that meet the above requirements are required to submit an NPRI report every year. More information is available in the ECCC Guide for reporting to the NPRI.


NPRI reports are submitted through ECCC’s Single Window Information Manager (SWIM), and include the following:

  • Facility information, such as location, parent companies, contact information;
  • Operating information such as applicable environmental permits, hours of operation, number of employees, activities conducted;
  • Substance information, consisting of the quantity that was released to the environment, disposed, or recycled, for each substance which was manufactured, processed, or used at the facility over the applicable reporting threshold; and
  • Pollution prevention information, including any activities conducted to reduce environmental impact during the reporting year.


The National Pollutant Release Inventory (NPRI) reporting deadline for the 2021 calendar year is June 1st, 2022.

Typically, all NPRI Reports are due June 1st of every year, however in 2020 and 2021 the deadlines were extended due to the COVID-19 Pandemic. Last years extension was not announced until two weeks before the original June 1st deadline, so it is recommended to monitor ECCC’s website for NPRI deadlines updates and reporting changes.


The NPRI Reporting framework is complex; an assessment of your facility’s operations is needed to determine whether the reporting thresholds are met. Keystone Environmental’s team of trained professionals stay up to date on current reporting regulations and requirements to ensure that we assist you efficiently in assessing your operations and collect the appropriate data required to complete your submission.

For more information about NPRI reporting and how it affects you, please contact our Engineering Department Head, Richard Johns.

Keystone Environmental can support you on your project needs and can help you navigate through these potential changes.  We can recognize issues, evaluate risks, and effectively apply professional judgement to  support you in achieving your project objectives.
