Map Your Property
In accordance with Ontario Regulation 41/24, KCCA regulates areas where development may have an impact upon the control of flooding, erosion or dynamic beaches, and where interference with wetlands and alterations to shorelines and watercourses may adversely affect those features.
KCCA’s regulation mapping is used as a screening tool. It provides a visual, GIS-based, first-step assessment that informs stakeholders of potential permit requirements before undertaking development. As a screening mechanism, it is not a “statutory map”. The mapping is used by KCCA, municipalities and the public as an illustration of where the Act and Regulation may apply. If your property is within a regulated area you should contact KCCA staff to discuss your project and determine if your property is affected by the Regulation and whether or not a permit will be required.
In some cases your property may cross the boundary of two Conservation Authorities. In this case you should contact both conservation authorities to determine if your property is within a regulated area.
If the webmap has indicated that your property is within a regulated area, you should contact KCCA staff to determine if a permit will be required. Conservation Authority permits are in addition to any building permits or other approvals you may need from your municipality.
KCCA’s permit application package can be found on our website here.
Steps to determine if your property is located within a regulated area:
- Open KCCA’s webmap
- Type your address in the text box located in the top right of the map, then select the correct address from those displayed.
- The map will zoom to the property searched. Click on the yellow highlighted parcel and a message will appear with information on the regulation status of the property.
- Any area highlighted in Red: Regulated areas- contact KCCA as regulations apply.
- Any area highlighted in Blue: Floodplain- regulations apply, contact KCCA
- If you would like to print the map, select the print button on the left side pan
How was the mapping updated?
In 2026, the most up to date data was used in the desktop analysis including 2018 Provincial LiDAR data, SWOOP 2020 aerial imagery, hydrology, soils, wetland and floodplain layers. A qualified third-party consultant undertook the evaluation. In addition, results were sample verified and reviewed by KCCA staff. The final report is available below.
