Abstract

Municipal parties in Canada are unique: They are not branches of national parties, they have no established ideological orientation and their lifespans vary considerably. In light of these characteristics, political scientists tend to overlook the factors that contribute to their emergence and disappearance as well as the diversity of their forms. The objective of this article is to fill this gap. Taking the city of Montreal as a case study, we draw on an electoral database spanning from 1960 to 2001 and a systematic press review to show that a party’s longevity is influenced by factors that are either external to the parties (institutional, economic and provincial political context) or internal to the parties (strong internal coordination, charismatic leader and ability to survive after a leader’s departure). For Montreal, this translates into a longer lifespan for two types of parties: platform-based parties and government coalitions.

Résumé

Résumé

Les partis municipaux au Canada sont uniques: ce ne sont pas des antennes des partis nationaux, ils n’ont pas d’orientation idéologique établie et leur durée de vie varie considérablement. Ces caractéristiques les ont relégués dans l’angle mort des politologues: les facteurs qui contribuent à leur émergence et à leur disparition, ainsi que la diversité de leurs formes, sont ignorés. L’objectif de cet article est de combler cette lacune. À partir du cas de Montréal et à l’aide d’une base de données électorales couvrant la période de 1960 à 2004 et d’une revue systématique de la presse, nous montrons que les facteurs susceptibles d’influencer la longévité d’un parti sont de deux types: (1) externes aux partis (contexte institutionnel, économique et politique provincial); (2) internes aux partis (forte coordination interne, leader charismatique et capacité à survivre après le départ du leader). À Montréal, deux types de partis ont ainsi une durée de vie plus longue: les partis basés sur la réalisation d’un programme et les coalitions pour gouverner.
