We call it the town of Weir, but its real name is the Municipality of Montcalm. Even in the phone book, however, it barely clings to its real name. In the Municipal listings in the blue pages the town hall (Hôtel de Ville) is usually listed with its address, most of the time marked as being in the town that is being described. An example of this can be seen in the listing for Prévost, which is identified as being on Curé Labelle Boulevard in Prévost. Of course this makes perfect sense and is consistent with the listings for most municipalities, but in Montcalm, the Hôtel de Ville is marked as being in Weir.
