You may get off at station Sherbrook on orange line, then take bus144 (it is the terminus), to Drolet/des Pins (1st stop)or de Bullion/des Pins (2nd stop). Follow the number and you will find 177. (less than 30 seconds).
I am sure teachers there will welcome you!
Sorry for my late replying. In brief, this French club/corner will be available every Sunday afternoon 1:30--3:30pm. Thus, they should be there on 30Sept. Again, the address is 177 Avenue des Pins, (cross section is Hotel-de-Ville, close to St-Denis)
Tel: 514-849-0753 (It is the right place and it is not a bookstore, but having a small small library of Bahaii Center)
Wish you would find them and enjoy the studying there
