The Ontario Line - Early Works: East Harbour Station


East Harbour Station early works will set the groundwork for other major construction on the Ontario Line and GO Expansion projects, reducing risk of construction delays to the main public-private partnership (P3) contracts by completing the Ontario Line and GO Expansion joint corridor work in advance of the main contracts for both of these transit projects.

East Harbour Station early works include:

  • reconfiguration of the existing Lakeshore East GO tracks to accommodate station facilities and future Ontario Line tracks;
  • construction of station facilities such as platforms and entrances;
  • replacement and expansion of the existing Eastern Avenue rail bridge to accommodate four Lakeshore East GO tracks and two future Ontario Line tracks; and
  • site preparation activities such as grading, demolition of existing structures where required, and utility relocation or protection.

The East Harbour Station Early Works Report has been prepared in accordance with Ontario Regulation 341/20: Ontario Line Project, Section 8 and outlines the purpose of early works, a description of local environmental conditions, potential impacts, proposed mitigation measures and a record of consultation. The Report also builds on previously-completed environmental assessment work in the area, including the East Harbour Station SmartTrack Station Environmental Project Report (2018).

Environmental impacts of East Harbour Station early works are being assessed in accordance with Ontario Regulation 341/20: Ontario Line Project (O. Reg. 341/20), under the Environmental Assessment Act. The early works assessment process includes the following:

  • reviewing and examining early works components and activities;
  • understanding local environmental conditions through desktop reviews and field studies;
  • assessing and evaluating potential impacts that early works components and activities may have on the environment;
  • proposing mitigation measures to avoid or reduce impacts and monitoring activities to verify effectiveness of mitigation measures; and
  • determining any municipal, provincial, federal or other permits and approvals that may be required as planning progresses.

 

The Draft East Harbour Station Early Works Report provides the following:

  • a description of the early works;
  • a map showing the site of the early works;
  • the rationale for proceeding with the early works and a summary of background information;
  • a description of the local environmental conditions at the site of the early works;
  • a description of all studies undertaken;
  • Metrolinx’s assessment and evaluation of the impacts that the preferred method of carrying out the early works and other methods might have on the environment, and Metrolinx’s criteria for assessment and evaluation of those impacts;
  • a description of any measures proposed by Metrolinx for mitigating any negative impacts that the preferred method of carrying out the early works might have on the environment;
  • a description of the means Metrolinx proposes to use to monitor or verify the effectiveness of mitigation measures proposed;
  • a description of any municipal, provincial, federal or other approvals or permits that may be required for the early works; and
  • a consultation record.
