Ottawa Stage 1 Light Rail Expansion 

As part of the City of Ottawa’s vision to build a world‑class transportation system, the Stage 1 light rail expansion introduced the new 12.5‑kilometer Confederation Line – connecting one of North America’s fastest‑growing cities with fast, sustainable, high‑capacity transit. The system includes 13 stations, with three located in a 1.5‑mile twin‑track tunnel beneath downtown Ottawa, marking the first conversion of an exclusive, built‑out bus rapid transit (BRT) corridor to light rail in North America.

What challenges did STV address?

The city required an integrated LRT solution capable of improving mobility, reducing congestion and upgrading an aging BRT infrastructure. The project demanded innovative approaches to reduce operational costs, define a compact station footprint, and implement reliable systems capable of supporting peak ridership demands – all within a dense and highly constrained urban environment.

What solutions did STV deliver?

Leading a multidisciplinary joint venture, STV provided planning, engineering, procurement and program management services for the design‑build delivery. During preliminary design, the team identified operational efficiencies that reduced long-term maintenance costs, optimized systems integration, shortened platform lengths and enhanced traction power and signaling capacity. Strategic relocation of interlockings and crossovers widened maintenance windows and improved long‑term system performance.

How does this project benefit the region?

The Confederation Line delivers a modern, efficient and environmentally responsible transit option, supporting Ottawa’s growth while reducing congestion and improving connectivity between residential, employment and governmental centers. The system enhances sustainability, strengthens economic development and provides a more reliable daily commute.
