R1 replacement bus service

When the O-Train is not running during regular Line 1 hours, R1 bus service may operate.

  • R1 buses serve all Line 1 stations and only make limited stops along the way.
  • If Line 1 is partially closed, R1 service may run only along the closed portion.

Express Shuttle E1

To better accommodate our commuters, we introduced a new express shuttle bus service last summer. This service operates alongside Line 1.

Our Shuttle Express service connects Blair to Lyon station during peak travel time on weekdays. This means you'll have a direct ride from Blair to downtown in the morning, and a smooth journey back to Blair in the afternoon.

The express service, known as E1, is designed to provide a more direct and efficient transit alternative. By bypassing intermediate stops, it significantly reduces travel time to and from the downtown core.

E1 routing

Blair to Lyon: From Blair Station, turn right to Gloucester Centre Roadaway, right to Blair, right to Highway 417, exit in Nicholas, left toMackenzie King Bridge, continue to Albert then Lyon station.

Lyon to Blair: From Slater and Lyon, continue to Slater, continue to Mackenzie King Bridge, turn right to Nicholas, continue to Nicholas, continue to Highway 417 east, continue to 174 and exit from blair, continue to Blair, turn left to Gloucester, left into Blair Station.

What happens during Line 1 delays or unplanned disruptions?

If rail service is disrupted, technicians will quickly respond. Our aim is to restore train service as quickly as possible. This is less disruptive to customers. If the issue is resolved within 15 minutes, train service will resume with only minor delays.

Sometimes, trains can continue to run along a single track. If full train service is not quickly restored, R1 replacement bus service may be deployed. 

The decision to run R1 service depends on various factors including:

  • Time of day
  • Frequency of the train service
  • Nature of the issue causing the disruption
  • Whether some trains can continue to run along a single track. In this case, R1 service is not usually required.

If R1 service is deployed, we will help you figure out where to go.

  • Check our home page. Look for the yellow box at the top of the page.
  • Look for the info screens at the stations
  • Listen for audio announcements
  • Staff in red vests may be on-site to help you as well

Planned Line 1 disruptions

We will notify you in advance of any planned rail maintenance. R1 schedules will be entered in the Travel Planner.

Real-time departure times will also be available:

  • On our home page using the Next Departures tool
  • By texting your stop number to 560560
  • By calling 613-560-1000, plus your stop number
  • Using a mobile transit app
