New route numbers

Service type icons

Numbers are organized geographically

  • Confederation Line is Line 1
  • Trillium Line is Line 2
  • Route numbers indicate where a bus travels, and if it connects to the O-Train

Numbers are the main identifier for routes in the OC Transpo network. Prominently displayed on the front of buses and trains, and on signs at stops and at stations, route numbering is a key wayfinding tool for customers.

Historically, OC Transpo route numbers have been organized by geographic area – for example, routes numbered in the 60s and 160s operate in Kanata; routes numbered in the 40s and 140s operate in Ottawa South — Alta Vista, and so on.

Route numbers for the new service are based on the same historical distribution by area. However, new numbers are provided for the cross-regional routes that will be split in two when the O-Train Line 1 begins operating.

Example of a bus stop sign

The O-Train Confederation Line will be numbered Line 1.

The O-Train Trillium Line will be numbered Line 2.

Bus route numbering ranges

Bus routes will be numbered according to their service type and where they operate:
