Bus network electrification

Being a leader in sustainable mobility

As a public transit provider, the STM is a natural ally in the fight against climate change. Electrifying our bus network is in line with our commitment to do even more and is an integral part of our 2030 Strategic Organizational Plan (2030 SOP - in french only).

Quick updates

Our bus fleet electrification has been in the works for a long time, and we’re giving it the thought and preparation it deserves.

Since 2016, we’ve integrated hybrid and electric buses into our network, carried out studies and research abroad, and tested different ways to reach our goal of a fully electric fleet.

We’ve developed a solid, research‑based plan for 2025–2026 and are now putting it into action to get ready for our new electric buses in 2025.

Plugged into the future

The transition to a fully electric network continues!

By choosing electric buses instead of hybrid ones, we estimate that we’ll reduce the greenhouse gas emissions of our bus network by more than 80% by 2040.

Our goal: only acquire 100% electric buses starting in 2025.

The many advantages of electrifying public transit

For our customers and the public

  • Modern, comfortable, air-conditioned buses
  • Improved quality of life in our neighbourhoods thanks to quieter, cleaner, greener buses

For the environment

  • A reduction in air pollution and GHG emissions
  • A reduction in our dependence on oil

For the economy

  • Support for Quebec companies
  • Use of clean (non-polluting) energy produced in Quebec

En route to a 100% electric network

A few years ago, we started making the shift toward hybrid technology by acquiring buses that emit 30% fewer greenhouse gases than diesel buses. At the same time, we ran tests to find the most suitable configurations and charging options for electric buses in order to best meet the full range of public transit needs.

Electric buses

Our bus fleet consists of 42 electric vehicles of different types: fast-charging, regular long-range, midibuses and minibuses.

Hybrid buses

We currently have more than 837 hybrid buses in service. Our goal is to replace these hybrid buses as they reach the end of their useful life to achieve a fully electric network by 2040.

Did you know? 44.4% of the buses in our fleet are either hybrid or electric.
