NPRI 2008 Facility Data Highlights

  • Over 8700 facilities reported on substances to the NPRI for 2008. Two-thirds of these facilities were located in Alberta and Ontario. The number of facilities reporting to the NPRI increased 5% between 2003-2008. There was a slight decrease between 2007 and 2008, however, due primarily to facility shutdowns in the mining and quarrying, sawmills and wood preservation, and motor vehicle parts manufacturing sectors.

  • Total pollutant releases reported to the NPRI decreased by 12% between 2003 and 2008, due largely to decreases from facilities in the electricity generation, primary metal smelting, wood products and petroleum refining sectors. Nevertheless, some facilities reported increased releases. Use the NPRI Online Data Search to query detailed pollutant release and transfer information for reporting facilities across Canada.
