Changes to the STO service to downtown Ottawa

As of June 21, there will be changes to all STO routes to downtown Ottawa. The buses will go three different ways. This will also mean schedule changes.

There will not be any changes on the Quebec side, with the exception of routes 11, 17 and 48, which will now take the Portage Bridge to Ottawa after servicing boulevard Maisonneuve.

As a result of these route changes to the downtown, the stops on Wellington Street between Kent and Elgin will no longer be in service, nor will the stop on Mackenzie Avenue.

The purpose of these changes is to better accommodate the connection between STO and the O-Train.

Details of the new service to downtown Ottawa

Regular routes and certain major peak period routes - 23, 24, 34, 134, 55, 59, 67, 87, 200 and 400, as well as routes 36, 37, 37, 38 and 371 (weekends and before 9 a.m. weekdays)

The navy blue line on the map identifies these routes. Heading into Ottawa, they will all serve Lyon Station and the Confederation Line.

  • Direction Ottawa, these routes will take the Portage Bridge, Lyon and Slater streets and the Mackenzie-King Bridge.
  • Direction Gatineau, these routes will start from the Mackenzie-King Bridge, then take Albert, Kent and Wellington streets, and then take the Portage Bridge as usual. 


Addition of the 134 designation for certain route 34 trips

Starting on June 21, route 34 trips ending at the Plateau district will be identified by the 134 designation. This will make it easier to distinguish trips ending at the Plateau district (route 134) from those continuing on to the Allumettières Park-and-Ride (route 34). This new designation will replace the 34x which was not supported by all information tools.

  • Direction Ottawa, there is no change in the designation of routes heading to Ottawa. Trips starting at the Allumettières Park-and-Ride or the Plateau district will be identified as route 34.

  • Direction Gatineau
    • Customers heading to the Plateau district can take either the 34 or the 134.
    • Customers heading to the Allumettières Park-and-Ride must take route 34.

Regular routes - 31, 33 and 35, as well as routes 36, 37, 38 and 371 (after 9 a.m. weekdays)

The turquoise line on the map identifies these routes. Heading into Ottawa, they will all serve Lyon Station and the Confederation Line.

  • Direction Ottawa, these routes will take the Macdonald-Cartier Bridge, King Edward, Rideau and Waller streets, the Mackenzie-King Bridge, and Albert, Kent and Wellington streets.
  • Direction Gatineau, these routes will take King Edward, Rideau and Waller streets, the Mackenzie-King Bridge, then Albert, Kent and Wellington streets, and then take the Portage Bridge as usual. 

Aylmer and du Plateau peak period routes - 22, 25, 26, 29, 40, 41, 45, 47 and 48

The orange line on the map identifies these routes, which are only in service during peak periods.

  • Direction Ottawa, these routes will follow their usual routes to the Portage Bridge, then take Wellington, Lyon, Slater and Bank streets.
  • Direction Gatineau, these routes will start at Lyon Station, then take Slater, Bank and Wellington streets, and then follow their usual route via the Portage Bridge.

Hull, Gatineau, Buckingham and Masson-Angers sectors peak period routes - 11, 17, 20*, 27, 85, 88, 93, 94, 95 and 98

The green line on the map identifies these routes, which are only in service during peak periods.
