Prolongement de la ligne GO de Lakeshore Est

Bowmanville Extension TPAP

In 2011, Metrolinx completed an Environmental Project Report (EPR) to assess the proposed expansion of GO transit infrastructure from Oshawa to Bowmanville. The EPR for the Oshawa to Bowmanville Rail Service Expansion and Whitby Rail Maintenance Facility, referred to as the ‘Project’, considered the potential environmental impacts of the Project and recommended appropriate mitigation measures.

Following the completion of the 2011 EPR, Metrolinx advanced the design of the Project. Based on Project refinements and revisions to the design approach since the completion of the 2011 EPR, the alignment and infrastructure requirements for the project have changed and Metrolinx initiated an EPR Addendum to assess the effects of these changes in scope.

Minister's Notice to Proceed

The Bowmanville Extension project was assessed under the Transit Project Assessment Process (TPAP) in accordance with Ontario Regulation 231/08. On December 11, 2023, the Minister of the Environment, Conservation and Parks issued a Notice to Proceed with the transit project following the completion of the Environmental Project Report Addendum and the 30-day Public Review Period. The Notice to Proceed can be found here.
