On September 29, the Light Rail Sub-Committee received a progress update on all three O-Train Extension projects.
You can watch the presentation here, view the latest construction progress video on O-Train East and West extensions or check out our summary below:
O-Train East Extension
Progress is being made with rail and overhead catenary system (OCS) installation and station construction advancing well. Work continues on the Trim Park & Ride and on all three pedestrian bridges.

O-Train West Extension
Rail installation at the Corkstown Yard (formerly called the Moodie Light Maintenance and Storage Facility) on the O-Train West Line has begun. The Cut and Cover tunnels continue to advance with excavation nearing completion, ongoing concrete pours for the walls and roof, and backfilling underway in some areas.

O-Train South Extension
In the south, final touches are being made at stations. Testing and commissioning has ramped up on both line 2 and 4 with vehicles running from Bayview to Limebank and South Keys to the Airport. Be sure to keep an eye out to see our longer trains!

Line 2 and Line 4 Handover Process
Once construction in the south is complete, final testing and commissioning will take place and the project will be handed over to the City of Ottawa. OC Transpo will then take over Lines 2 and 4 and take additional time for training and to prepare for launch and bus service changes as required. This will include additional testing and dress rehearsals.
To find out more about the many steps to prepare for launch, watch our update here.

🏆A year in review of the O-Train Extension project
2025 review
Remember when the O-Train extensions were just plans? 2025 changed everything.
We opened Lines 2 & 4 (hello, airport rail link!), powered up the East Extension for testing, rolled out the West’s first train, and completed station after station.
This is the story of how Ottawa moved toward a tripled rail network in one landmark year.

OttaTalk
The OttaTalk team invited transit leaders into the studio to talk about Ottawa’s busiest room — the TOCC.
Hosts interviewed Director Joel Lemieux and Manager Brad Tubman about the command centre that handles 400,000 calls each year:
no windows, but eyes on the entire city.
