South Nation Conservation works with local municipalities, the Province of Ontario, and the Department of Fisheries and Oceans to ensure waterfront developments are safe and environmentally sound.

SNC’s Regulation, made under Section 28 of the Conservation Authorities Act, is titled Ontario Regulation 170/06 Regulation of Development, Interference with Wetlands and Alteration to Shorelines and Watercourses

Ontario Regulation 170/06 ensures public safety and protection of property from natural hazards. The regulation also works to prevent pollution and destruction of sensitive environmental areas such as wetlands, shorelines, and watercourses. 

Ontario Regulation 170/06 establishes Regulated Areas where development may be subject to flooding, erosion or dynamic beaches; or where interference with wetlands and alterations to shorelines and watercourses might have an adverse effect on those environmental features. Any proposed development, interference or alteration within a Regulated Area requires a permit from SNC.

Ontario Regulation 170/06 requires that permission must be obtained from SNC prior to

  • altering a river, stream, or watercourse; or
  • interfering with a wetland.

SNC permission must also be obtained before undertaking development activities in or near the following areas: 

  • floodplains;
  • unstable slopes;
  • unstable soils and bedrock;
  • hazardous lands;
  • wetlands; and
  • other areas where development could interfere with the hydrologic function of a wetland, including areas within 120 metres of all provincially significant wetlands
