Environmental Project Report Addendum
Published on April 14, 2022
To bring existing environmental studies up to date with changes to the project, Metrolinx prepared an addendum to the previously-completed 2009 Environmental Project Report (EPR) and 2014 EPR Addendum – which includes studying existing environmental conditions and completing an environmental impact assessment.
This report includes a final description of the Yonge North Subway Extension project, and an assessment of environmental impacts, mitigation measures, monitoring activities, potentially required permits and approvals, and other components as outlined in O.Reg 231/08.
