Canada Federal Contaminated Sites Inventory

This dataset depicts known contaminated sites under the jurisdiction of Canada's federal agencies and consolidated Crown corporations, including non-federal sites for which the Government of Canada has accepted some or all financial responsibility. A contaminated sites is defined as "one at which substances occur at concentrations (1) above background (normally occurring) levels and pose or are likely to pose an immediate or long term hazard to human health or the environment, or (2) exceeding levels specified in policies and regulations." (http://www.tbs-sct.gc.ca/fcsi-rscf/home-accueil.aspx?Language=EN&sid=wu1281891127).

This dataset was created by the Conservation Biology Institute using publicly available information obtained from the Treasury Board of Canada.

Please note: not all sites contained in the Federal Contaminated Sites Inventory are present in this dataset. This dataset does not include sites that have not yet been classified according to the National Classification System of the Canadian Council of Ministers of the Environment. Only those that could be converted to shapefile format and did not appear to be erroneously located (well outside borders of Canada) were retained in this dataset. The Treasury Board of Canada Secretariat is the authoritative source for all matters related to the source data used to create this dataset.
