PROVINCIAL STUDY PROCESS

The 407 East EA Study was undertaken in accordance with the requirements for an Individual EA under the Ontario Environmental Assessment Act (OEAA).

On June 3, 2010, the Minister of the Environment (MOE), with the approval of Cabinet, made a decision to allow the 407 East transportation corridor to proceed subject to strict conditions. The approval by MOE is for the 407 Corridor as detailed in the Environmental Assessment (EA) Report, including the extension of 407 from Brock Road in Pickering to Highway 35/115 in Clarington and the two north-south links connecting the 407 extension to Highway 401, one in Whitby (West Durham Link) and the other in Clarington (East Durham Link).

The main phases of the project under the OEAA were as follows:

  • Project Initiation
  • Transportation Problems and Opportunities (Purpose of and Rationale for the Undertaking)
  • Transportation Alternatives (Alternatives to the Undertaking)
  • Route Alternatives (Alternative Methods for Carrying out the Undertaking)
  • Preliminary Design
  • EA Report / Documentation
