Project overview

What is the purpose of this study?

Stage 2 logo – Stage 2 is part of Ottawa’s proposed 2013 Transportation Master Plan

This study was initiated by the City of Ottawa to develop an approved plan to extend and expand the City's existing diesel-powered Trillium Line (O-Train) service from Greenboro Station to Riverside South (Bowesville Road) and to the Ottawa Macdonald-Cartier International Airport.

The plan will include options to service the growing communities of Riverside South and Leitrim, the Airport and adjacent lands, as well as new stations at Gladstone and Walkley roads on the existing O-Train line. The plan also allows for a future conversion to electric light rail transit (LRT) technology.

The study is comprised of two parts. Part A of the study addresses the main line extension to Riverside South (Bowesville Road), including new stations at Gladstone and Walkley roads. Part B of the study addresses a potential Trillium Line spur line connection to the Ottawa Macdonald-Cartier International Airport. Note that Part A of the study has been identified by Ottawa City Council as part of the City's Stage 2 affordable LRT plans to be implemented in the near term.

What is the study area?

The primary study area includes the existing Trillium Line corridor between Bayview and Greenboro Stations, the current Walkley Yard maintenance and storage facility, the proposed southern extension from Greenboro Station to Riverside South (Bowesville Road), and a branch to the Airport, as shown below.

Why extend the Trillium Line to Bowesville (Part A)?

The need to extend rail transit service to Riverside South and further to Barrhaven was first identified in the City's 2003 Transportation Master Plan (TMP). This need was driven by planned population growth in the south urban community: a projected 54,600 residents and 27,900 jobs in Riverside South and 22,500 residents and 12,600 jobs in the South Nepean Town Centre when these communities are fully built out. To meet this demand, in 2006 the City's North-South Corridor LRT EA Study (N-S LRT EA) identified an approved recommended plan to extend electrically powered rail transit from the Rideau Centre to Barrhaven Town Centre.

The City's updated 2013 TMP identifies construction of the electric LRT line south of Bayview Station as something which will likely take place beyond 2031. In order to provide an immediate benefit to transit riders from the growing communities south of the Airport, the City plans to extend the Trillium line to a Park and Ride and transfer station near Bowesville Road, and to construct a Bus Rapid Transit (BRT) Transitway facility linking Bowesville with Barrhaven Town Centre through Riverside South. Bowesville Station was identified as the preferred end point for an O-Train extension in the Trillium Line South Rail Expansion Project Feasibility Study, which was presented to City Council in 2012. EA approval for the Transitway portion was obtained through the Barrhaven – Riverside South Rapid Transit (Barrhaven Town Centre to Leitrim Park and Ride) Environmental Assessment Study (BRRT) in 2013.

What is the current study process?

This study is following Ontario's Transit Project Assessment Process (TPAP) (O. Reg. 231/08), which is approved under the Ontario Environmental Assessment Act. Under the TPAP, the City must consider alternative designs for the transit project, undertake public and agency consultation, assess the potential environmental impacts of the recommended plan, and identify measures to mitigate these impacts.

The study will also address potential implications of federal and National Capital Commission properties and the potential requirements for federal permits and funding.

As part of the study process, an Environmental Project Report (EPR) will be prepared for public review. Following the public review period and the issuance of a Notice to Proceed from the Minister of the Environment, the project will be considered to have EA approval and may proceed towards financing and construction.

How long will the study take?

The EA process requires a comprehensive consultation program involving many stakeholders, including the City of Ottawa, the Airport, the NCC, approval and regulatory agencies, local community associations and businesses, special advisory and interest groups and members of the public. The study is expected to take approximately 15 months to complete.

How can I get involved?

You are encouraged to participate in the study by attending consultation events or contacting the study team directly with information, comments or questions. Updated project information will be posted periodically on the study website.

An Open House will be scheduled as an opportunity for interested persons to learn about the study and provide input on the recommended plan or any other aspect of the study. Notification for the open house will be provided through local newspaper notices, emails to the study mailing list, and postings on this website.
