Regulation Implementation Guidelines
Note: Our Regulation Implementation Guidelines have been updated and approved by the Board of Directors on June 23, 2023.
These Regulation Implementation Guidelines (formerly Watershed Development Guidelines) have been developed to help enhance consistency and administrative decision-making for the implementation of Lake Simcoe Region Conservation Authority’s Development, Interference with Wetlands and Alteration to Shorelines and Watercourses Regulation (Ontario Regulation 179/06) made under the Conservation Authorities Act.
These Guidelines provide general approaches to the processing of applications under Ontario Regulation 179/06. They are the operating principles or the general norm for the implementation of the Regulation.

Stormwater Management Guidelines
This document will provide guidance to municipalities, the development community and their consultants regarding the stormwater management and Erosion/Sediment Control requirements of the Lake Simcoe Region Conservation Authority in accordance with the Lake Simcoe Protection Plan and Provincial Policy Statement.

Comprehensive Stormwater Management Master Plan
The Lake Simcoe Protection Plan sets out specific requirements for the management of stormwater in existing and planned settlement areas, through the preparation of comprehensive Stormwater Management Master Plans (CSWM-MP). This document provides direction to municipalities on how to prepare and implement CSWM-MPs for settlement areas located in the Lake Simcoe watershed, in accordance with the intent of Policy 4.5-SA of the Lake Simcoe Protection Plan.

Hydrogeological Assessment Submission
This guidance document has been developed by the Conservation Authorities Geoscience Group which is made up of Conservation Authority hydrogeologists. The main purpose is to provide information and guidance material to Conservation Authorities, their municipalities and consultant hydrogeologists related to hydrogeological assessment requirements that can be used to ensure comprehensive evaluations of potential impacts associated with development on natural ecological features and functions that are supported by groundwater resources.

Permit Application Hearing Guidelines
The Conservation Authorities Act (Section 28) requires the applicant be party to a hearing by the local Conservation Authority Board, for an application to be refused or approved with conditions. Further, where staff are recommending that a permit be revoked under Ontario Regulation 179/06 a hearing will be held to provide the applicant with the opportunity to show cause why the permit should not be cancelled.

Offsetting Plans and Policies
As new urban growth occurs, phosphorus loads
will be controlled to meet pre-development phosphorus loading levels. Any
remaining stormwater phosphorus that cannot be controlled would require an
“offset" to achieve pre-development phosphorus loading levels.

Development proposals and infrastructure projects subject to
Planning Act or
Environmental Assessment Act approvals that will result in the loss of wetland and/or woodland natural heritage features, despite having followed the mitigation hierarchy, will be required to compensate for the loss of these features.

Water Budget Policy
Recognizing the importance of recharge areas to sustaining a healthy watershed, the Lake Simcoe Protection Plan includes a number of policies to help identify and protect SGRAs and ESGRAs.
The approach taken within the LSPP follows three basic steps: 1) define and identify SGRAs/ESGRAs; 2) develop guidance for their protection and restoration, and 3) incorporate policies into municipal official plans to protect, improve and restore. This document will expand on the three points above by developing a Water Budget Offsetting Policy for those areas where it is demonstrated that the post-development infiltration is unable to match the pre-development infiltration volume and an infiltration deficit remains in the post development scenario.

Lake Simcoe Climate Data: A Reference Document to Support the Completion of Water Balance Assessments
This document aims at providing a standard dataset for land development applicants and their consultants to use when completing water balance analysis. Qualified Persons should exercise professional judgment and flexibly to adapt the data provided when considering specific site conditions and when new information or data becomes available.
