Projects that alter a property near any waterbody, wetland, steep slope or floodplain in the Rideau Valley require a permit under Ontario Regulation 41/24: Prohibited Activities, Exemptions and Permits (O. Reg 41/24).
The RVCA is mandated under Section 28 of the provincial Conservation Authorities Act to enforce this regulation through permitting and inspections. This ensures proposed developments minimize the natural hazards associated with development in floodplains and erosive areas, which could otherwise require expensive protective measures in the future or even put people and property in harm’s way.
If you are planning to do any of the following work near a lake, river, stream, floodplain, steep slope or wetland, you may require approval from the RVCA:
- construction, reconstruction, erection or placing of a building or structure of any kind
- changes that would alter the use or potential use of a building or structure
- increasing the size of the building or structure or increasing the number of dwelling units in the building or structure
- site grading
- the temporary or permanent placing, dumping or removal of any material, originating in the site or elsewhere
- straightening, changing or diverting or interfering with an existing channel of a river, creek, stream or watercourse, or changing or interfering with a wetland.
