Green Line LRT Project

Green Line project history and milestones

The Green Line has been planned for Calgary’s future since the 1980s. The Green Line was initially planned to be built as bus-only lanes called a transitway. While a transitway would not provide the capacity and reliability of an LRT service, this option would improve service in communities, without the significant initial capital investment required for LRT. The transitway was planned to be extended and converted into an LRT line in the future, as funding became available.

In July 2015, the Government of Canada announced that up to $1.53 billion from the Public Transit Infrastructure Fund would be awarded to the Green Line as an LRT project. This announcement offered the opportunity to explore building the Green Line as an LRT from the beginning, providing all three levels of government could provide matching contributions. As of July 2017, all three levels of government have announced funding support for Stage 1 of the Green Line LRT totaling $4.903 billion.


2012 North Central LRT Planning Begins

In 2012, The City began planning for, what was then known as, the North Central LRT. A new LRT line that would connect Calgarians from the Northern Hills Communities to downtown. Through this planning it was determined the NCLRT and the Green Line SE would be one continuous line, connecting in the Centre City.

Council approval for bus-only Transitway, with plans to convert to low-floor LRT.

The project became known as the SETWAY. Council approved this plan and directed The City to continue engagement with key stakeholders to finalize station locations and Transit Oriented Development opportunities and to report back with a plan explaining the population and land use data on which the ridership forecasts were prepared.

2013 Council provides funding to build the "Green Line"

Council allocates $52 million/year in tax room from 2015-2024.

These funds are used to create a dedicated transit fund to build the North Central and Southeast Green Line. The southeast leg of this project is re-named to the Green Line Southeast Transitway.

2014 Recommendations for Green Line North

Administration presented recommendations of Green Line North (formerly known as North Central LRT) Route Planning Study Recommendations (TT2014-0916).

Work Plan for Green Line SE approved

The work plan outlined the Green Line Southeast magnitude and complexity, project milestones until construction start, and potential early roadwork projects.

2015 Council Approves Green Line North

This approval set the route down Centre Street North and connected the Green Line SE and North Central LRT as one route.

Federal Government commits $1.5 billion for Green Line LRT

In summer 2015 the Government of Canada committed funding for a Green Line LRT officially converting the project from a bus-based transit system to an LRT.

Green Line SE Engagement

The Green Line team hosted many public engagement opportunities to finalize the southeast route.

2016 Centre City Alignment Approval

In October 2016 the Centre City alignment of an underground tunnel and four stations was approved by Council.

Beltline Alignment Approval

In December 2016, the Beltline alignment of 12 Avenue underground with a station at Centre Street was approved, finalizing a 4 km tunnel to connect the Green Line North and Green Line Southeast.

2017 Green Line long-term vision and Stage 1 approval

City Council approved Green Line LRT long-term vision, including a 46 km route from 160 Avenue N to Seton, 28 station locations, and Transit Orientated Development (TOD) plans. Stage 1 of construction was also approved to extend from 16 Avenue N to 126 Avenue SE, including 14 stations.

Provincial funding announcement

The Government of Alberta pledged up to $1.53 billion over eight years to support Stage 1 construction of the Green Line LRT. The funds will come from the Climate Leadership Plan.

2018 Work continues on the Green Line

The project team continued to refine the design and challenge assumptions made during the preliminary design phase of the project to prepare for the release of contract documents. This work primarily focused on the constructability of the 4 kilometre tunnel.

2019 Funding agreement finalized

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

Light Rail Vehicle

In February, the RFQ for a new fleet of low floor LRV’s was released in Q1 of 2019.

Council approves splitting Stage 1 into two contracts

In July, Stage 1 of the Green Line has been split into two contracts, 4 Street S.E. to Shepard and 16 Avenue N to 4 Street S.E. to accommodate further review of the downtown and Beltline alignment.

Release Request for Qualifications for Segment 1

In August, the RFQ for construction of segment 1, 4 Street S.E. to Shepard was released. We received information from interested bidders on their qualifications to work on the project.

2020 City approves updated Stage 1 alignment

On Tuesday, January 28 the Green Line team presented an updated Stage 1 of the Green Line route to City Council. These changes will help address construction risk, cost and customer experience concern on the project.

Engagement on the changes followed.

The City recommends an updated Stage 1 Alignment to Council

In March 2020 Administration recommended an updated Stage 1 alignment through the Centre City, the updated alignment will go to Council in June.

Release Request for Proposals for Segment 1 (4 Street S.E. to Shepard)

The RFP for segment 1, 4 Street S.E. to Shepard, has been released to a shortlisted group of successful proponents identified through the RFQ process.

Engagement on the Green Line

The future Green Line LRT will touch numerous communities and areas, each with unique identities, and diverse area planning needs. The public engagement process strives to accommodate and respect the individuality of each community while facilitating meaningful dialogue to gather the necessary design information. In most cases, public input is one of many factors that must be considered by the project team when making decisions. Other factors include cost, community impact, environmental considerations, technical feasibility, etc.

Starting in 2015, the Green Line team has worked closely with communities, businesses, developers, and other key stakeholders along the route to identify opportunities, understand and mitigate community concerns. The engagement process enabled the team to understand and align with community objectives while balancing the needs of transit customers.

2021 Construction of Segment 1 starts - 4 Street S.E. to Shepard

Construction of tracks and stations for segment 1, 4 Street S.E. to Shepard, will begin in 2021. Details about the construction schedule will be available once we have secured a contractor.

2022 Construction of Segment 2 starts - 16 Avenue N to 4 Street S.E.

Construction of tracks and stations for segment 2a, 2 Street S.W. to 4 Street S.E. will begin in 2022.
