High-Frequency Lines

  1. High-frequency lines

High-frequency lines

Our convenient high-frequency lines provide efficient transportation with buses running more often on our busiest routes. There are two types of high-frequency lines: all day and rush hour.

High-frequency lines are easy to use and offer many benefits: 

  • Large area of coverage with many transfers to other high-frequency lines and to the métro, REM and exo
  • Reserved lanes for faster, more regular service
  • Departures generally* every 2 to 12 minutes, Monday to Friday, all day or during rush hour
  • Flexibility to suit your needs

Enjoy consistent service without too much trip planning, for greater freedom and peace of mind.

Bus network redesign 2026

With the bus network redesign and the arrival of the Anse-à-l'Orme REM, changes to high-frequency lines will take effect. See the list below for details on the changes.

Two types of high-frequency lines

Take your time! Our high-frequency lines offer predictable, efficient service with departures generally* every 2 to 12 minutes, Monday through Friday. 

The two types are:

  • All-day high-frequency
  • Rush-hour high-frequency

All-day high-frequency lines

Between 6 a.m. and 8 p.m., they offer more service on our busiest routes, in both directions.

*Buses on our high-frequency lines are scheduled to run generally every 2 to 12 minutes. However, this is subject to various factors, including traffic, construction work, road blocks and weather. Although our team works continuously throughout the day to reduce the impact of these factors, they sometimes result in slower service and delays to the planned schedule.
