Important Information about the O-Train Line 2 Detour

  • During the closure, buses will replace train service and will run along the entire line, stopping at all stations, as well as South Keys, Walkley and Heron stations and Preston/Gladstone.
  • Buses will operate at least every 15 minutes and more frequently if required to provide additional capacity and space for physical distancing among customers onboard. The frequency will be increased as required as the current situation evolves.
  • Service levels will increase for the fall and winter service period to account for increased demand.
  • Line 2 will reopen when construction is complete.
  • The expansion will see eight new stations and an additional 16-km of rail line.
  • The expanded line will continue from Greenboro to Limebank in Riverside South, and a new rail link will be built to the Ottawa Macdonald-Cartier International Airport.

O-Train Shutdown

On Feb. 22, 2019, City of Ottawa officials held a technical briefing to outline results of the Stage 2 Light Rail Transit (LRT) procurement and selection of a consortium to build the project. Phase 2 will see the extension of the Trillium Line (the O-Train) south to Riverside South with a link to the Ottawa Macdonald-Cartier International Airport.

As part of its Phase 2 LRT project, the City of Ottawa has affirmed its plan to shut down the O-Train for a two-year period beginning in May 2020. At this time, the city is projecting the new LRT service on the line will resume in September 2022. The city has stated that there will be improvements to bus service to campus during the shutdown.

Members of the Carleton community need to be aware of this O-Train service interruption and plan accordingly.

Information about the Phase 2 LRT plan is available on the City of Ottawa’s project website.
