Project history

The story of the Green Line LRT has evolved over time with engagement and input from Calgarians throughout. 

The need for a Light Rail Transit (LRT) line in the southeast has been under consideration by Council since the mid-1980s as communities in the area developed quickly and continue to grow. Rapid transit was envisioned for the north as early as 1967, and Centre Street N. has the busiest Bus Rapid Transit (BRT) corridor in the city. 

Planning for Green Line as we know it today began in 2011. See the key milestones, public open houses and engagement sessions that helped shaped the project over time.

Engagement with Calgarians has been part of the Green Line planning process.

Project timeline


First groundbreaking for Green Line’s Public Gardens Initiative (August)
The redevelopment of George Moss Park in Ogden is a significant step towards creating inclusive and vibrant public spaces along the Green Line. This is the first of a minimum of six outdoor community spaces that will be located within 500 metres of future Green Line stations.

Construction begins on 78 Avenue Project in Ogden (July)
Following evaluation of the RFP, the Green Line Board selected Graham Construction to build the 78 Avenue Project. Before building the Ogden LRT station and tracks, the 78 Avenue Project will complete vehicle and pedestrian tunnels under the Canadian Pacific Kansas City Railway (CPKC) corridor to enhance mobility and pedestrian safety around the future Green Line LRT Ogden Station.

Development Partner selected (April)
Following a successful procurement, the Green Line Board approved the Development Phase Agreement and selected Bow Transit Connectors (BTC) as Green Line’s Development Partner. This announcement launched the Development Phase, which allows for collaboration, design progression, and agreement on project costs, risks, and overall schedule between Green Line and BTC, before signing a Project Agreement.

Land acquired for Eau Claire Station (January)
The Green Line Board and City of Calgary reached an agreement in principle with Harvard Developments to acquire the land for the future underground station at Eau Claire. This station is both the temporary terminus for Phase 1 of the Green Line LRT, from Shepard to Eau Claire, and serves as the future connection between the north and south legs of Green Line.


Light Rail Vehicle (LRV) mock-up (November)
Green Line received a mock-up of its new low-floor LRV. The mock-up will be used to validate Green Line’s technical requirements and ensure accessibility, and will eventually become a training simulator for future transit operators.

Delivery Partner selected (November)
Following a Request for Proposals evaluation, CSIX Partners was selected as the Delivery Partner. They will supplement the Green Line team in support of delivering Phase 1 (Shepard to Eau Claire) across a range of project functions, including commercial management, technical support, project controls and construction management.

Green Line hosts Business Information Session (November)
An information session was hosted to introduce Calgary’s local contractors, suppliers and trades to the two proponent teams competing to design, build and construct Phase 1 of the Green Line LRT.

Request for Proposals issued for Phase 1 (September)
The Request for Proposals (RFP) was released to select a proponent to design, construct and finance Phase 1, from Shepard to Eau Claire, of the Green Line LRT. The RFP was released to the two proponent teams, Bow Transit Connectors and City Link Partners, who were short-listed through the Request for Qualifications stage.

Two proponent teams selected (July)
Following the Request for Qualifications (RFQ) for construction of Phase 1, from Shepard to Eau Claire, the Green Line Board approved two proponent teams, Bow Transit Connectors and City Link Partners, to advance to the Request for Proposal (RFP) stage.

Request for Qualifications released for Phase 1 development (March)
Green Line released the Request for Qualifications (RFQ) for construction of Phase 1, from Shepard to Eau Claire. The RFQ creates a short-list of candidates, from which a Development Partner can be selected to build Phase 1 of the Green Line LRT.


Contract awarded for Light Rail Vehicles (LRVs) (November)
The Green Line Board and The City selected CAF (Construcciones y Auxiliar de Ferrocarriles) as the supplier of our new fleet of LRVs for the Green Line LRT Project. The contract includes 28 modern low floor LRVs.
