Check out
http://www.infoscan.urgence.qc.ca too, they have the best online database of quebec frequencies.
I hope you realize that over 90% of radio comms are in french in this province (almost 100% of police, fire and EMS are in french).
The DB here isn't too bad. It has the RSP EDACS system (where you will find EMS for the Montreal area) and the Montreal SSIM system, which as noted is P25.
Since a 2020 doesn't even receive 800 MHz let alone track trunking systems, about all that is left is SPVM (Montreal cops) and some SQ (Surete du Quebec).
And ham radio and rail, air, and marine, of course.
As for the French language comms, I would hope anyone with a Canadian education could at least get the gist of the comms if not every nuance. The codes for police, fire and EMS are widely available and make it that much simpler ... assuming you can count to 100 in French.
