FAQs and resources

Here are some commonly asked questions about Green Line and our resource library that contains reports and documents of interest. 

About the Green Line

Is the Green Line going ahead?

Yes! Phase 1 of the Green Line LRT from Shepard to Eau Claire was reviewed, approved and funded by The City of Calgary, Province of Alberta and the Government of Canada in 2021.

Where does it go?

Phase 1 of Green Line spans 18 kilometers from Shepard Station at 130 Avenue S.E. to Eau Claire at the north end of downtown. Green Line will have 13 stations and provide connections to the Red and Blue LRT lines and three MAX rapid transit routes. 

See more details on connections to the transit network.

What's the budget?

The Green Line has $5.5B in funding from The City of Calgary, the Government of Alberta, and the Government of Canada.

How many people will ride the Green Line?

Phase 1 of Green Line is expected to have up to 55,000 daily riders in its first year and attract up to 18,000 new transit riders. 

Transit users on the corridor will save an average of 10 minutes per trip and riders using Green Line from the southeast to downtown could save up to 25 minutes compared with existing bus service.

Drivers using Deerfoot Trail or other major roads could save up to 10 per cent of their commute time due to reductions in road congestion.

Who is overseeing this project?

Green Line is overseen by an independent Board of Directors appointed by City Council that is comprised of citizens who have extensive experience delivering major infrastructure projects. The Board works closely with Green Line’s Executive Team of experienced professionals with demonstrated backgrounds in infrastructure development.

Is Green Line facing cost inflation pressures?

Infrastructure projects across North America are facing rising costs driven by inflation, supply-chain disruptions, market conditions and key skills shortages. Those pressures are impacting Green Line and all City infrastructure projects as identified in The City’s January 2024 Corporate Risk Report. To address the market conditions, the Green Line team is working closely with contractors on costs and industry experts to evaluate the project from station design to procurement strategy. 

What are the benefits for people who won't ride Green Line regularly?

As Calgary experiences extraordinary population growth, the need for Green Line will only grow. Along with extending LRT service to underserved communities in the southeast, Green Line supports other City plans and will unlock much-needed new housing options and transit-oriented development. It is forecasted to increase land values by $8 billion to $10 billion along the route and generate additional property taxes exceeding $200 million annually by 2038.

Construction and development

When will construction start?

A series of advance construction projects have been underway for some time with projects downtown, in the Beltline and Ogden. Main construction of stations, tracks and tunnels is expected to begin in Fall 2024.

Where will construction begin first?

The construction schedule and plans will be determined working with our development partners during the Development Phase before the Project Agreement is signed in 2024. Once the agreement is in place the schedule and plans will be confirmed and shared.

When will the Green Line LRT open?

It is too early to provide a specific date. Main construction of Phase 1, is on track to begin in Fall 2024 and based on projects of similar size and scale, it should take approximately six years to complete construction. The construction schedule will be developed prior to the signing of the Project Agreement.

Why does construction take so long?

Phase 1 of Green Line is the largest infrastructure investment in Calgary’s history. It is a megaproject and requires the construction of stations, tracks, a tunnel downtown, multiple bridges and elevated guideways, a maintenance and storage facility for Light Rail Vehicles (LRVs), Park and Ride facilities and much more.

Comparing the scale and timeline to other LRT projects in Calgary:

  • The first leg of Calgary’s LRT system spanned 12.5 kilometres from Anderson Station in the south to downtown with 16 stations and took four years to construct.
  • The West LRT expansion from downtown to 69 Street Station spanned 8.2 kilometres of track, with six stations and took three years to construct.

Who is building the Green Line?

Bow Transit Connectors (BTC) was announced as Green Line’s Development Partner in May 2023.  BTC brings shared expertise in underground, above-ground structures, and LRT design and construction to deliver Phase 1 of the Green Line LRT Project.

During the Development Phase, BTC is advancing design while the project cost, schedule and risk allocation are negotiated, prior to signing the Project Agreement in 2024 and beginning main construction. Their teams will be supported with local contractors, suppliers, and trades.

An early works program, currently underway, is being performed by PCL Construction, the third-party utilities (ENMAX, Telus, etc.) and Graham Construction. 

Business support

How is the Green Line supporting businesses during construction?

Green Line has a Business Support Program with a team on-the-ground to keep businesses informed and prepare them for the impacts of nearby construction. The best way business owners can connect with Green Line and stay informed is to register your business with us.

Examples of how we support businesses include:

  • Direct communication to provide updates on construction and planned disruptions.
  • Ensuring safe access to businesses is maintained as regularly as possible, throughout construction.
  • Developing initiatives to encourage Calgarians to support businesses, including coordinating with City programs such as the Seasonal Public Patio program and developing Green Line wayfinding, detour and “businesses open during construction” signage.
  • Featuring local businesses on our social media channels and website.
  • Meeting regularly with our Business Insights Panel to understand current challenges and concerns, and to share plans and ideas to support businesses.
  • Encouraging staff, contractors and the public to support local businesses (our Ogden Local Business Guide).

Trains and safety

What's being done to ensure Green Line will be a safe transit system?

Building safe transit infrastructure and providing safe Light Rail Vehicles (LRVs) are top priorities and there is more information on our station safety and LRV safety pages. 

Once Green Line opens, it will be operated by Calgary Transit and The City of Calgary is committed to improving safety and security on the transit system. The Transit Public Safety page outlines steps being taken to improve transit safety.

The City is increasing staff, including Peace Officers, outreach teams and security guards, and making improvements to station lighting and surveillance. In May 2023,  they also released a report on the potential of implementing a “closed system.” 


Why did the Green Line choose a low-floor Light Rail Vehicle (LRV)?

Low-floor LRVs are now the preferred choice for new LRT systems across North America because they offer improved accessibility, enhanced vehicle and pedestrian safety, and the ability to integrate easily into the community. 

With low-floor LRVs, train stations at street-level don’t need long ramps, stairs, or large platform structures. The low platforms are curb height (33 centimetres compared with 98 centimetres for high-floor trains), which allows for simpler station designs, resulting in cost savings when building the stations.

Can the Green Line LRVs share tracks with the Red and Blue lines?

The Urbos 100 low-floor LRVs will operate exclusively on Green Line. Due to the low-floor design, the station platforms on the Red and Blue Lines are too high. There are also differences with the existing electrical network that prevents the Green Line LRVs from running on the Red and Blue lines.

Future plans

When will we know more about Phase 2 (Eau Claire to 16 Avenue N.)?

The Green Line team is focused on delivering Phase 1 of Green Line from Shepard to Eau Claire. The Board is committed to managing costs and risks of Phase 1 and there is no timeline to make a decision on a recommendation to Council for Phase 2

When will the north extension (16 Avenue to 160 Avenue N.) and south extension (Shepard to Seton) be built?

The full 46-kilometre vision for Green Line extends from Seton in the south to 160 Avenue N. City Council will make the determination on future north and south extensions based on transit demand, balancing other priorities and if funding is available. 

Stations from south to north include:

  • Seton
  • Hospital
  • Auburn Bay/Mahogany
  • McKenzie Towne
  • Prestwick
  • Shepard
  • Douglas Glen
  • Quarry Park
  • South Hill
  • Ogden
  • Lynnwood/Millican
  • Highfield
  • 26 Avenue S.E.
  • Ramsay/Inglewood
  • 4 Street S.E.
  • Centre Street S.
  • 7 Avenue S.W.
  • Eau Claire
  • 9 Avenue N.
  • 16 Avenue N.
  • 28 Avenue N.
  • 40 Avenue N.
  • McKnight Boulevard
  • 64 Avenue N.
  • Beddington
  • 96 Avenue N.
  • North Pointe
  • 144 Avenue N.
  • 160 Avenue N.

Will the Green Line cross the Bow River via bridge or tunnel?

It was determined in 2019 that the best option was to build an LRT bridge over the Bow River, connecting Eau Claire station to Crescent Heights. City Council approved this plan in 2020. However, this work is outside the scope of Phase 1 construction.

More information about the preliminary planning and design of the Bow River Bridge is here.

Will Green Line connect to the airport?

Phase 1 will not connect to YYC Calgary International Airport but there are plans for an Airport Transit Connector linking both the Green Line and Blue Line to the airport.  Visit our future extensions page for more information.

In July 2023, the City of Calgary announced a study to identify the optimal rail connection and alignment between downtown Calgary and the airport. The study will include a ridership review, and development and evaluation of different alignment scenarios. For more information, visit the Airport Transit Study page.

Does Green Line align with the Government of Alberta’s new rail plan?

The Alberta government’s vision for a Passenger Rail Master Plan was announced in Spring 2024. It will require a strong intermodal transit network in Calgary to achieve its goals and the Green Line team is looking at opportunities to support this vision.
