Although significant efforts have been made to disguise Montreal's subway as Calgary by replacing almost all signs and advertisements with English-only equivalents, we can still some references to Montreal in some shots. For instance, we can see a map of Montreal on the wall at one subway's entrance, there is a regulation sign on the wall with reference to STCUM (Société de Transport de la Communauté Urbaine de Montréal), and there is a warning sign in one vehicle with at least one sentence in French.
