Changes to Regulation Implementation Guidelines

Formally know as Watershed Development Guidelines

As of January 3, 2022, our Watershed Development Guidelines have been reviewed and updated. As part of the update we considered the title of the document and our role as a regulatory agency. As a result, the document is now called, Regulation Implementation Guidelines. These Guidelines provide general approaches to the processing of applications under Ontario Regulation 179/06.

Housekeeping updates were required for several sections of the Guidelines for various reasons including changes to the Conservation Authorities Act, as well as changes in daily operations and to provide further clarification of requirements to applicants. 

Significant changes to the Implementation Guidelines include:

  • A new section (2.1.4) relating to Minister Zoning Orders (MZOs) and the use of ecological offsetting in these scenarios.
  • A new section (3.4) outlining LSRCA’s Customer Service Strategy and complete submission requirements.
  • Changes to Chapter 5 Flooding Hazard Guidelines to include spill area guidelines, changes to the Holland Marsh Specialty Crop Area guidelines, and clarification on size requirements for additions in the floodplain.
  • Updates to Chapter 7 Erosion Hazard Guidelines, including reference to the MNRF’s “Technical Guide for River and Stream Systems, Erosion Hazard Limit”.
  • Clarifications added into sections on flooding and wetlands, outlining studies that may be required with undertaking development.
