This is the office where you purchase the MTL Passeport. The passport lets you visit a few of Montreal's museums for a 3-day period. The passport also includes free bus rides across the city.
The building looks like it is located in a seedy part of town (a few blocks away from Chinatown).
The clerk who helped us is very nice.
I liked the passport program. However, I wish they included more museums. I also wished that the organizers would let the transit service know about this program because a few times, some transit people told us the pass was not a legitimate bus fare. Someone get that memo out!
