Welcome to the Developers section. The STM wishes to provide developers with data about its bus schedules and routes and information about its metro service.
GTFS - realtime data (real-time bus schedules and locations) and API i3 (métro, bus and elevators service updates)
To access the GTFS - realtime data and the API i3, connect to the STM developer portal
- More information about GTFS realtime
- Documentation on how to use our API can be found on the STM developer portal
GTFS data (bus schedules and métro frequency)
- Description of available data and a few STM specifications
- More information about GTFS (General Transit Feed Specification)
Change to bus line groupings
Our all-day and rush-hour high-frequency lines (buses with departures roughly every 2 to 12 minutes) have a new distinctive visual identity on our STM network information tools.
To represent these 31 bus lines on your app, please use the corresponding hexadecimal colour code shown in the GTFS.
The schedules will change in 2023-2024 on the following dates:
2023: October 30
2024 `January 8, March 25, June 17, August 26 and October 30
The GTFS data are usually available 10 days before the schedule change .
Shapefile format for Geographic Information Systems (GIS)
Bus lines (shapes.txt) and bus stops (stops.txt) in the GTFS are available in shapefile format for easier integration into GIS. Shapefile specifications are available here.
Files available in MTM NAD83 Zone 8.
MOBILES APPS GALLERY
There is a page on this website where all the transit apps using the STM data are listed. You'll see a description and a logo for each app. With this information, the clients will be able to find the app that suits their needs.
