Constructing swimming pools is considered DEVELOPMENT under the Conservation Authorities Act and a permit will be required if the pool is proposed within a regulated area.
Why You Need to Apply for a Permit
Under Ontario Regulation 166/06, the TRCA regulates and may prohibit work from taking place within valley and stream corridors, wetlands and associated areas of interference and the Lake Ontario waterfront. If your property is regulated, you must apply for a permit from TRCA prior to carrying out any new development. Constructing a pool is considered development under the Conservation Authorities Act.
The Permit Process
- Make a complete hard copy TRCA Permit Application submission.
- Your application is assigned to the appropriate Planner.
- The assigned Planner reviews the application and determines whether it is complete. You will then be notified via email of the status.
- Once the application is deemed complete (including the application fee), the Planner will begin their review and schedule a site visit. If additional technical review is required, your application will also be circulated to TRCA technical staff.
- Once the Planner has completed the site visit, their initial review, and has received technical comments from technical staff, an initial set of comments will be provided to you. Additional studies or a revised submission may be required.
- Once the revised submission is received, the Planner will circulate any required studies and drawings to the appropriate technical staff.
- Once all technical comments have been addressed, and the Planner has confirmed the proposal complies with applicable TRCA Living City Policies, the Planner will process the TRCA permit for approval.
Note: If your property is within the City of Toronto, please also make the necessary submission to the City’s Ravine and Natural Feature Protection (RNFP) staff concurrently for any tree injuries or removals as a result of the proposed development or construction. Please refer to the City’s Urban Forestry website for more information.
Please note that the Conservation Authorities Act is applicable law and your municipality cannot legally issue a building permit until a TRCA permit or permit clearance has been obtained for works within a regulated area under Ontario Regulation 166/06.
