Welcome to Montreal! The city is slowly waking up after a long winter and it feels good. If I were you I'd show up at the music faculty of Montreal University (200 Vincent d'Indy street) looking like a student, go straight up to the 8th floor (if I remember) and just find a practice room. Tons of them up there. All as big as my closet but still, you get a closed door and an upright. Usually in the evening things are quieter than during the day. The 6th floor grands are much busier. If I remember they close at 10pm or thereabouts.
Here's a web site with address and more info:
https://www.umontreal.ca/plancampus/pavillons/pav04.htmI also think that EPILOGUE Musique in Montreal, 514-842-6573, offers a rehearsal studio equipped with 5'9" Aeolian Grand. Opened 7 days a week. Price is $10/hr. I would call ahead though. Contact Alexandre Dulude. I say their ad on
www.lespac.com, ad number 3051943. I'm just reporting this information, I have no experience or opinions on this company.
You may also call the West Island Music Conservatory and inquire about any available practice time there, they're at (514) 428-5080, also STUDIOS DE PRATIQUE Musitec at (514) 831-8499 and/or Jam Avenue Studios at (514) 337-2526. I have no information on rates or availability for these three contacts.
If you were closer I'd say come on over and let's talk music, let's compare notes, and then I'd leave you alone with my Leach upright.
Some concerts that may be of interest while you're here:

www.scena.org to see what's happening concert-wise in and around town. Grab a paper copy of La Scena Musicale magazine (free) and you may find something in there too about practice studios.
If you find nothing please write back and I'll do further research.
Enjoy your stay!
