Ontario Regulation 178/06 establishes Regulated Areas where development could 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.

What is Development?

Development is defined in the Conservation Authorities Act to mean:

  • the construction, reconstruction, erection or placing of a building or structure of any kind;
  • any changes to a building or structure that would have the effect of altering the use or potential use of the building or structure, increasing the size of the building or structure or increasing the number of dwelling units inthe building or structure;
  • site grading, or
  • the temporary or permanent placing, dumpingor removal of any material, originating on the site or elsewhere.


The Regulation pertains to areas that are within river or stream valleys, adjacent or close to the shoreline of Lake Erie and inland lakes, wetlands and other areas where development could interfere with the hydrologic function of a wetland, and areas where soil or bedrock conditions are hazardous.

Typical activities that may require LPRCA permission in a regulated area include, but are not limited to:

  • construction of all buildings and additions includingmodification or reconstruction of foundations which support existing buildings;
  • changes that would alter the use, or potential use of a building or structure;
  • breakwalls, revetments, rubble, groynes, etc;
  • docks, stairs, decks, gazebos;
