Green Line LRT project - Industry information

Green Line - Industry information

On June 26, 2017 City Council approved the recommended 46 km Green Line LRT alignment and station locations, as well as the first stage of construction. This is a major milestone for the project, and ensures that the long-term vision for the Green Line can be implemented over time, as funding becomes available.


​April 2019 – Additional details on upcoming enabling works and supplemental contracts

The City continues to move the Green Line LRT project forward through our enabling works program including the 78 Avenue overpass and diversion track listed below.

Supplemental contracts are also being prepared that include projects to mitigate construction impacts to citizens during the main contract construction. These include adjacent road upgrades, signaling and pedestrian accommodation projects as well as business revitalization initiatives. To learn more, see our April update.

Main project contracting strategy

The decision has been confirmed to procure the majority of the main project using a single Design Build finance model, which aligns with Council's approval in March of 2018.

The Request for Qualifications (RFQ) for the Green Line LRT project will be issued in Q2 of 2019. In addition to the main contract, a number of supplemental contracts will be released utilizing a variety of procurement models. A future briefing will be issued outlining the scope of the supplemental contracts, and their expected release to the market. A specific date will be issued in a future briefing for the release of the main contract RFQ.

On February 1, 2019 The City released the RFQ for the Green Line's new fleet of Light Rail Vehicles (LRV). The Green Line will use low-platform LRV technology that has not been used before in Calgary.

Prospective applicants intending to respond to the RFQ are advised that The City will be providing additional direction concerning the provision of traction power services in the RFQ. Therefore, prospective applicants should defer the selection of any traction power service providers until the Request for Proposals stage of the Green Line LRT Project.

Interested parties should visit MERX and Alberta Purchasing Connection, for this opportunity to provide Calgary with the latest in LRV technology and its newest LRT line.

Funding Status

On January 30, 2019 the Government of Canada, Government of Alberta and The City of Calgary signed a funding agreement for stage 1 of construction of the Green Line LRT. This agreement marks a major milestone for the project and finalizes the joint investment in Calgary of nearly $5 billion by all three levels of government.

Contracting Strategy

On March 19, 2018 City Council approved the Design-Build-Finance (DBF) delivery model recommended by City Administration following an approval by the Priorities and Finance Committee (PFC) on March 6, 2018.

Various models were investigated, ranging from full Private-Public Partnerships (P3) to more traditional methods like Design-Build (DB). For details on the material that was presented to City Council, view the meeting minutes.

Public Involvement

Public engagement has been a key piece in planning the Green Line over the last two years. More than 10,000 participants have taken part in over 100 engagement events across the city and online. Engagement on the route alignment and station locations is now complete. Further public engagement will focus on the details of how the Green Line will function and integrate into communities and access and circulation in the station areas and neighbourhoods along the line.


The first stage of construction for Green Line LRT is recommended to extend from 16 Avenue N (Crescent Heights) to 126 Avenue S.E. (Shepard). This will be the longest segment of LRT ever constructed at one time in Calgary's history.

  • Stage 1 of construction for Green Line will be 20 km long and will include 14 stations, the Centre City tunnel, a LRV maintenance facility, and approximately 70 low floor LRT vehicles.
  • Building the full tunnel in the Centre City is a key component to ensuring this line can be expanded in the future.
  • With the tunnel in the Centre City constructed, Calgary will be well positioned to expand the line in affordable and incremental pieces to the north and the southeast as funding becomes available


Stage 1 is projected to begin construction in 2020, and is anticipated to open in 2026.

Enabling works

Calgarians living or working along Stage 1 of the Green Line will have already started to see construction activity along the future Green Line route. These construction activities include items like utility relocation, environmental remediation and land preparation. Doing this work now means it will be easier to build the Green Line LRT tracks and stations in the future. See the construction page for more details on individual projects.
