The main objectives of Ontario Regulation 166/06 are to ensure public safety and protect property with respect to natural hazards and to safeguard watershed health by preventing pollution and destruction of sensitive environmental areas such as wetlands, shorelines and watercourses.  Ontario Regulation 166/06 establishes Regulated Areas where development could be subject to flooding, erosion or dynamic beaches, or where interference with wetlands and alterations to shorelines and watercourses might have an adverse effect on those environmental features.  Under Ontario Regulation 166/06, any proposed development, interference or alteration within a Regulated Area requires a permit from TRCA.

As an agency responsible for managing the renewable natural resources within nine GTA watersheds, TRCA continuously strives to improve its policies and approach to land use planning and development. TRCA just completed a comprehensive review and update of the Valley and Stream Corridor Management Program (October 1994), which is now superseded by a new policy document, The Living City Policies for Planning and Development in the Watersheds of the Toronto and Region Conservation Authority (November 2014).
