The City of Ottawa is embarking on a two-year project to improve and extend the Light Rail Transit (LRT) Trillium Line. The project features an existing 8 km north to south line where two new stations will be added to better serve local communities and address service gaps. The existing stations will undergo platform extensions and amenity upgrades to shelters, furniture, wayfinding and safety. As part of the 11 km extension, four new stations will be built with facilities for rail/bus interchange, park and ride and commuter parking. A 4 km spur line is also part of the overall project and will include an additional two new stations serving the Ottawa McDonald-Cartier International Airport and the EY Centre.

NORR is designing seven of the thirteen aboveground stations including Bayview, Carling, Carleton, Mooney’s Bay (Confederation), Greenboro, South Keys and Bowesville. Both South Keys and Bowesville are new stations completely designed from concept to construction documentation, while the other five stations vary in scope of renovations. The design of the stations reinforces a system identity unique to Ottawa’s existing and future light rail network and is adaptable for further extensions. The primary design features will create an intuitive, safe and positive ridership experience, with improvements for passenger movements, accessibility and connectivity between station plazas and local buses, trains and the community.

NORR is also designing the new Maintenance and Service Facility (MSF) that will include a main service and maintenance building, management and operations center, and a rail vehicle wash building and various structures to support daily fueling, inspecting and servicing of the LRT rail vehicles.

When completed, the Trillium LRT line will eventually integrate with Ottawa’s Confederation LRT line and bus transit network, support transit-oriented development within local communities. The project is being delivered as a Public Private Partnership (P3) Project by a large multidisciplinary team led by SNC Lavalin.
