 It is composed of the mayors of each of the member municipalities and possibly other elected municipal officials as well as a warden ("préfet").Depending on the RCM, a warden can either be appointed by the council (in which case the warden must be one of the mayors) or elected by universal suffrage (in which case they cannot hold any other elective office).The voting strength of each municipality on the council is determined in part by its population, but a formula is used to prevent a small number of large municipalities from making decisions unilaterally.
