OpenStreetMap
In order to get a route-planning service, they moved from their in-house map to a service provided by Microsoft Virtual Earth. This means that even if I could use the data to map bus locations (it's certainly a definite no-no now), the way it is configured makes it thoroughly complicated (you can't get a list of lines stopping at a certain stop anymore grrr). Also, I had been vaguely considering approaching the RTC and STM about whether their buses are equipped with GPSs (I'm fairly sure they are) and freeing that data for OSM, though I'm not clear I'd have gone about that, but the RTC data is now almost certainly locked in some sort of license agreement.

I would say that it's pretty sure they are not equiped with GPS since I've read sommthing a few month ago about de AMT adding GPS to their bus so they would know what is the real usage of their bus which wasnt possible beffore they make de OPUS system and they said that was the first time something like that was done in québec.
but anyway you can still do it but I would suggest to ask for some electronic file that could be parsed and then be added by a bot in OSM for the STM it's sure they have one since it's needed for their azimut service.
and by the way be patient for an answord... I'm still waiting for one about something else and it's been 2 or 3 month... might work better if you dont just write an email thought...
