Ontario Regulation 170/06 establishes regulated areas where development may be subject to flooding or erosion; 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 the South Nation Conservation Authority, including;
- altering a river, stream, or watercourse; or
- interfering with a wetland.
You can apply for a permit from SNC online.
SNC permission must also be obtained before undertaking development activities in or near 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.
