National Pollutant Release Inventory (NPRI) datasets
The following NPRI datasets are available through the Government of Canada Open Data Portal and contain data as of September 29, 2016. There are a number of factors to keep in mind when using and interpreting NPRI data. For more information see Using and interpreting NPRI data.
Note that facility reported data is available in the original language of submission.
Data Set Description
|Online Query Tool|
Use the query tool to search detailed information on pollutant releases (to air, water and land), disposals, and transfers for recycling reported by facilities to the NPRI. You can search a report by filtering by reporting year, company, substance, location, and industry type.
Predefined queries are also available for aggregated data by province, industry type, and substance, for the last five reporting years.
|Single Year Tabular Data||These files contain the most commonly used NPRI data fields within a simplified tabular format, including all facility-reported pollutant releases, disposals and transfers for recycling for a given year, listed by facility and substance. |
Available in CSV and XLSX for the three most recent years.
|Five Year Release Data Aggregated by Province, Industry Type, and Substance|
These files contain NPRI release data for the past five reporting years, aggregated by Province, Industry Type and Substance, and disaggregated by media (air, water and land). The number of reporting facilities represented by each aggregated data point is included*. The results can be further explored using the pre-defined queries available in the online query tool.
*The number of facilities returned by the online NPRI data search may differ from the number contained in the download files. The online results take into account the facility’s reported releases, disposals and transfers, but do not distinguish between media. They also include facilities reporting only under Ontario Regulation 127/01 and facilities submitting “did not meet criteria” reports.
Available in CSV.
|Bulk Data (1993 to present)|
These files contain data from 1993 to the latest reporting year available. These datasets are in normalized or ‘list’ format and are optimized for pivot table analyses.
Available in CSV and XLSX.
These files are currently available from 1993 to 2014. The updated files will be published at a later date.
|Map Layers - Geographic Distribution of NPRI-Reporting Facilities|
Different data products to depict the geographic distribution of NPRI reporting facilities are available.
Additional information on how to view the NPRI geospatial data, important considerations and other programs’ initiatives is available.
|Map Layers - Geographic Distribution of Total Reported Releases by Media Group, and of Total Disposals and Transfers|
These CSV files and open mapping services (shapefile, WMS, GeoJSON, KML, WFS and ESRI REST) contain the geographical distribution of facilities reporting direct releases, disposals and transfers for the most recent reporting year. They are grouped by media of release, and by disposal and transfer. Facilities are categorized by industrial sector and total reported quantities.
