Electrification underway...

Hybrid buses have been gradually replacing diesel buses since spring 2016, paving the way for the electrification of the network. Based on projections that take into account the useful life of a bus, as well as depreciation and fleet upgrades, we expect our fleet to be fully electric by 2040.

Our 100% electric buses

We currently have 30 electric buses.

Limiting GHG emissions

According to a 2016 study, every tonne of GHGs emitted by the STM can prevent about 20 tonnes from being emitted in the Greater Montréal area. Electrifying our network will further contribute to the fight against climate change by reducing our own GHG emissions.

Our 30 long-range New Flyer buses have been in operation on our regular bus routes since 2019. They have a range of 250 kilometres and are equipped with air conditioning to ensure customer comfort.

The advantages of electric buses

  • More comfortable thanks to smoother handling on the road
  • Quieter ride
  • LED lighting

Depending on the bus configuration:

  • Air conditioning
  • USB ports
  • Second reserved area for wheelchair users
  • Charger plug

Our infrastructure

When we talk about electrifying our surface system, it’s not just about acquiring fully electric vehicles. It’s also about retrofitting our bus garages so that we can integrate new technologies.

Our lab at the Stinson bus garage

We’ve been electrifying our infrastructure to make it compatible with electric buses. The Stinson bus garage was the first to be partially electrified.

Stinson has been our lab for all things electrification since 2019, which is when we began running tests with the charging technologies at the garage to find the best ways to maximize the use of our electric buses.

Did you know that the Stinson bus garage is LEED Gold certified and has one of the largest green roofs in Quebec?

The garage is equipped with pantographs and charger plugs with a capacity of 150 kWh. This is the minimum power required to achieve the ideal charging time and optimize service delivery with electric buses.

We’ve already equipped our Angrignon and Square-Victoria–OACI stations with two outdoor pantographs to charge the electric buses on line 36 Monk.

We’ve also installed pantographs inside the Stinson bus garage. And because a bus garage never sleeps, we had to pull out all the stops! Keeping the bus aisles clear and protecting the work areas without disrupting service is a challenge in itself. We were one of the first transit agencies to install indoor pantographs.

We now have nine indoor pantographs at the Stinson bus garage.


The charger plugs are very safe and can be handled without special gear. We installed 44 outlets like this, plus two mobile chargers for the maintenance area.


Using a supervisory control and data acquisition (SCADA) system, we can view and monitor the buses’ charge status remotely and make sure that buses are recharged as needed.


Above are the 12 chargers that power the buses in the four electrically equipped aisles. Since this equipment generates heat, we installed a ventilation and air conditioning system to control the room temperature.
