Calgary and Alberta Clash Over Green Line LRT Costs and Risks

City claims provincial redesign adds $1.3 billion in costs, while province insists Calgary bears responsibility for overruns and legal liabilities.

The City of Calgary estimates the cost of the province's revised Green Line LRT alignment at $7.5 billion, $1.3 billion more than the provincial estimate of $6.2 billion.
The Alberta government redesigned the Green Line to include elevated tracks downtown and five additional stations, extending the line to 17 kilometers.
City officials argue the provincial plan underestimates costs and excludes prior investments, while raising concerns about potential legal risks tied to reduced property values near the elevated tracks.
Calgary City Council voted to continue negotiations with the province but demanded shared accountability for cost overruns and delivery risks.
Mayor Jyoti Gondek has called for the public release of AECOM’s full report, which remains confidential, to ensure transparency and informed decision-making.
