Contaminated Site or Soils

Potential Approval, Permit or Code of Practice Requirements:

  • A site profile is a screening form for identifying potentially contaminated sites. A site investigation is the key means of gathering information to determine if a site is contaminated. Findings of these investigations are compared with environmental quality standards in the Contaminated Sites Regulation to determine the presence of contamination by substances in soil, surface water, ground water, and sediment. Once it is determined that a contaminated site requires cleanup, the site owner generally has a number of options for site remediation which differ in the extent of involvement of the Ministry of Environment and by environmental consultants.

    Contaminated Soil Relocation Agreements regulate the movement of soil from contaminated sites, taking into account the soil quality and environmental conditions at the deposit site.

    Application and notification forms, instructions and schedules to be used by site owners and operators, consultants and others involved in assessing and cleaning up contaminated sites are online.


The Environmental Management Act is the main law governing contaminated sites in the province. It lays out standards for site identification, assessment, and cleanup (“remediation”). Other provisions are set out in the Contaminated Sites Regulation. The Ministry of Environment administers these legal requirements and provides direction for compliance on the following web-sites:
