Development & Permits

If you are planning to build or alter land (e.g. excavate or fill) near a wetland, watercourse, or along a shoreline, you may require a permit from Mississippi Valley Conservation Authority (MVCA) or municipal planning approval.

The MVCA administers a permitting process to protect peoples’ lives and property from natural hazards such as flooding and erosion, and to maintain the health of the watershed.  Permits are issued in accordance with the provincial Conservation Authorities Act and Ontario Regulation 41/24: Prohibited Activities, Exemptions and Permits.

Conservation Authorities are a commenting agency for applications made under the Planning Act such as severances, site plans, subdivisions, zoning by-laws amendments, and minor variances. MVCA comments on the potential impact of development on natural heritage issues, (water quality, storm water management, wetlands, aquatic resources, etc.), natural hazards (flooding and erosion) and in some areas of the watershed, on-site servicing such as wells and sewage disposal systems). The Province has mandated that Conservation Authorities comment on natural hazards and MVCA has agreements with its member municipalities to assist in addressing natural heritage issues.
