The City of Calgary says the Alberta government’s revised Green Line LRT alignment would cost $7.5 billion — and not the $6.2 billion figure both the city’s previously approved plan and the new provincial plan suggest.
Calgary city councillors met Tuesday to discuss the details of the province’s new project plan that was announced last Friday, attached to a confidential report from infrastructure consulting firm AECOM.
AECOM was hired by the province for $2.5 million earlier this fall and tasked with designing the new alignment, which stretches just over 17 kilometres and has 12 stations instead of the previous plan’s seven.
“Based on the $6.2 billion rough order of magnitude estimate provided by AECOM, the province’s external consultant, the city identified $1.3 billion in known costs and risks that were not included in their work,” reads a city news release Tuesday evening.
“At $7.5 billion, this exceeds the $7.2 billion cost estimate, based on the city’s 60% design for the Shepard to Eau Claire tunneled alignment, presented in July 2024.”
All of this comes after the province announced a significant revision of the city’s previous Green Line LRT plan on Friday, in a saga involving multiple disagreements between levels of government about how the project would take form.
The new iteration of the Green Line would feature no tunneling through Calgary’s downtown, which drew criticism from the province in the project’s last alignment.
The Green Line is the worst political football we could be playing with.

The revised plan has the LRT running through the downtown core along 10th Avenue on elevated tracks, then curving north to Seventh Avenue, enabling riders to connect with the Blue Line and Red Line.
AECOM’s full report remains confidential. The city says it will continue working collaboratively with the province in order to find a solution.
