Permits Under Ontario Regulation 166/06 - Development, Interference with Wetlands and Alterations to Shorelines and Watercourses
Do I Need A Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Permit From the Conservation Authority?
Under Ontario Regulation 166/06 - [33K] , the Toronto and Region Conservation Authority regulates and may prohibit work 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 the Conservation Authority in order to do any of the following works:

How Do I Confirm that My Property is Regulated?
Most of the lands regulated by the Conservation Authority have been mapped in detail. The Regulation Limit mapping, which shows the Authority's Regulated Areas is available through our head office.
If you live close to a stream, river, valley, or watercourse of any kind, a wetland or on the waterfront, and you wish to determine if your property is affected by Ontario Regulation 166/06 or other TRCA policies and programs, you can use our regulation area search tool as a first step to screen your property. However, the information in this viewer is not intended to constitute advice nor is it to be used as a substitute for specific advice from a qualified professional. You should not act, or refrain from acting, based upon information shown in the viewer without verifying the information with TRCA staff and, as necessary, obtaining professional advice regarding your particular facts and circumstances. In order to do this please contact Planning and Development at the Conservation Authority. Please be prepared with a legal description of your property (e.g. municipal address, lot and concession lines, plan or block number) and a location map. If you want written confirmation and a detailed review of how your property is affected by our regulation, we also provide a Property Inquiry Service for a fee.
How Do I Apply for a Permit?
What Happens to My TRCA Permit Application?
Your Development, Interference with Wetlands and Alterations to Shorelines and Watercourses permit application will be assessed to determine whether the proposed works will affect the control of flooding, erosion, dynamic beaches, pollution or the conservation of land. Recommendations will be forwarded to the Executive Committee of the TRCA, who will decide whether to approve or refuse the application. Before refusing an application, however, the Executive Committee will notify the applicant and hold a hearing to which the applicant or his/her agent shall attend. Upon hearing the submission of the applicant/agent and reviewing other information submitted, the Executive Committee will make its final decision. If refused, the applicant will be notified of the reasons in writing. Within the 30 days of receipt of the Notice of Refusal, the applicant may appeal to the Mining and Lands Commissioner who may dismiss the appeal or grant permission.
To ensure that your permit application is reviewed in time to be included on the agenda, please ensure that your complete permit application is submitted 8-10 WEEKS prior to the scheduled Executive Committee date.
Why is Regulation 166/06 Important?
Ontario Regulation 166/06 is important because it protects watercourses, wetlands, shorelines and valley lands, and it protects you and your neighbours throughout the watershed. Regulation 166/06 enables us to contribute to the health and integrity of the regional greenspace system and to maintain or improve the hydrological and ecological functions performed by valley and stream corridors. These corridors are important for groundwater recharge and discharge; they provide fish and wildlife habitat; contain rich archaeological and natural heritage resources; and they improve air quality.
In addition, Regulation 166/06 ensures that works within the regulated areas will not create a hazard to life and property in other parts of the watershed. Every year, the Toronto region experiences severe storms and periodic flooding. Unrestricted development within a floodplain increases the risk of "loss of life, personal injury, and property damage." Fill placed on a valley or bluff slope can aggravate existing erosion problems or create new ones. Development can also affect neighbouring properties by changing the physical characteristics of the floodplain and stream. Likewise, unrestricted development along the Lake Ontario waterfront may be damaged by flooding due to high lake levels and severe wave action.
Works requiring authorization from Fisheries and Oceans Canada
On Monday, November 25, 2013, amendments to the Fisheries Act, Applications for Authorization (under Paragraph 35(2) (b) of the Fisheries Act Regulations) and Information Requirements Regulations came into force. As a result of these amendments and other changes within DFO, proponents must now ensure their projects meet the DFO requirements under a self-assessment process. The Fisheries Act requires that projects avoid causing serious harm to fish unless authorized by the Minister of Fisheries and Oceans Canada. The following links provide further information:

Please note that although TRCA no longer review projects under the Federal Fisheries Act, the Authority continues to deliver programs and services directed towards the protection, restoration and management of aquatic systems, including fish and fish habitat, as an integral component of watershed management and our objectives for the Living City. Since TRCA is responsible for administering Ontario Regulation166/06 under the Conservation Authorities Act for works within regulated areas it continues to provide quality service in this regard, including review of impacts on aquatic systems. In addition, TRCA also provides Plan Review services under the Planning Act and Environmental Assessment Act to our municipal partners including the provision of advice as it relates to impacts on fish and fish habitat.
