Don Mouth Naturalization and Port Lands Flood Protection Project – Environmental Assessment

Toronto and Region Conservation Authority, on behalf of and in cooperation with Waterfront Toronto and the City of Toronto has completed the Environmental Assessment (EA) for the Don Mouth Naturalization and Port Lands Flood Protection Project (DMNP).

In order to implement the preferred conceptual design for the DMNP, provincial EA requirements must be met through the completion of an Individual EA, as defined in the Ontario EA Act. An Environmental Assessment is a study, which assesses the potential environmental effects (positive or negative) of a proposal. Key components of an environmental assessment include:

  • Consultation with government agencies and the public
  • Consideration and evaluation of alternatives
  • Management of potential environmental effects

Final Submission: DMNP EA (March 2014)

The completion of the DMNP EA caps off an extensive planning process whose roots can be traced to a public meeting at the Ontario Science Centre in 1989. As required under section 6.2(1) of the Environmental Assessment Act and according to the Terms of Reference approved by the Minister of the Environment and Climate Change on August 17, 2006, TRCA submitted and received approval of its environmental assessment in March of 2014.

A copy of the DMNP EA can be downloaded by Chapter in PDF format below. Access to previous versions of the EA as well as stakeholder consultation material can be found here.

The DMNP EA Terms of Reference

The first step in the application to proceed with a project under the Environmental Assessment Act is the approval of a terms of reference (ToR). The ToR serves as a framework, or workplan, for how the EA will be designed and implemented. As an important component of the overall EA process, the public and other interested parties are given the opportunity to participate in the development of the ToR, and several public forums were held to receive feedback from stakeholders. The final version of the ToR, approved August 17, 2006, along with supporting Stakeholder Consultation Report, can be found below.
