Trillium phase III multi-use pathway

Project Status: 

Construction notice (July 2018)

In August 2018, the City of Ottawa will begin construction on Phase III of the Trillium Multi-Use Pathway in your neighbourhood. This project will provide the final cycling link from the Glebe Community, Dow's Lake and Lansdowne Park to the Carling Trillium Line Transit Station.

Who: CSL Group Limited has been retained by the City of Ottawa to construct the project.

Why: This work is needed to improve the connectivity of the multi-use pathway network in your neighbourhood.

What: The City recently completed 2 kilometres of new pathways along the east side of the O-Train Trillium Line, which currently connects the Ottawa River Pathway to Dow's Lake. This project will complete the final missing link between this recently completed pathway to Prince of Wales Drive. This missing link will complete connectivity along a 10 kilometre section of Cross-Town Bikeway Route 6.

When: The work is to commence in August 2018 and is anticipated to take approximately eight weeks.

Where: Construction will take place on the parcel of land bordered by Carling Avenue, Preston Street, Prince of Wales Drive and the O-Train Trillium Line Corridor. The new multi-use pathway will run from Carling Avenue to Prince of Wales Drive and continue east along the north side of Prince of Wales Drive to the Preston Street intersection.


Accessibility is an important consideration for the City of Ottawa. The City makes every effort to provide access through and around construction sites. If you require special accommodation, please contact the Contractor’s Project Manager or the City’s Project Manager noted below.

Construction disruptions

The Contractor will take every precaution to minimize interruptions to the everyday life of your family and/or operation of your business, but, as you can appreciate, there may be some inconvenience during the course of the work, such as traffic delays, dust, and noise. We would like to thank you for your patience and co-operation.

Pathway and sidewalk closures

The existing gravel pathway connecting Carling Avenue and Prince of Wales will be closed during construction. The sidewalk on the north side of Prince of Wales between Preston Street and the bridge over the O-Train will also be closed during construction. A signed detour will be in place to direct pathway users around the area. Vehicular access to and from the Dow’s Lake parking lot will be maintained at all times.

Functional design study - online consultation

The City of Ottawa has initiated a functional planning study to complete the multi-use Trillium Pathway between its current southern terminus at Carling Avenue and the National Capital Commission’s pathway at Dow’s Lake. The extension to this facility is identified as a Community Connectivity project in the approved Strategic Initiatives of this term of Council (2015-18).  In addition, the design further develops the cross-town bikeway that links to the south urban community along Prince of Wales Drive, as described in the Ottawa Cycling Plan of 2013.  It further improves connectivity to the O-Train Trillium Line’s Carling Station from the south.  This project is in partnership with the National Capital Commission.  This project is also supported financially by the federal government’s Public Transit Infrastructure Fund.

The purpose of the project is to address a missing cycling link for recreational, utilitarian and commuter users at an important junction of several routes, as well as to complete the Cross-town Bikeway #6 at this location.  

Study update: August 2017

Following an online public consultation held between March 30 and April 14, 2017 and further staff discussion, a recommended functional design concept has been identified.  The revised plan is based on technical feasibility, affordability and community input.

Revised Functional Plan

  • Proposed is an upgrade of the existing crushed-stone trail running parallel to the O-Train Trillium Line to an asphalt multi-use pathway (MUP) of standard 3-m width. 
  • Between this MUP’s new endpoint at Prince of Wales Drive and the intersection with Preston Street, raised cycle tracks and a new sidewalk will be provided. 
  • The existing on-road bike lane adjacent to Queen Juliana Park will be shifted and provided with a painted buffer zone between it and the general-use southbound traffic lane.
  • Unsignalized crossings of Prince of Wales Drive as previously proposed have been eliminated.

Residents are encouraged to review the available project information and drawings and to provide their input.
