French term 'Municipalité de paroisse'
The territory of a religious parish established as a municipality.
The Commission de toponymie du Québec describes a parish municipality (municipalité de paroisse) as "the territory of a parish (in the religious sense) established as a municipality". Many of these remain from the days in which the Catholic Church served as an effective governmental structure in areas without established secular municipal government.
In most cases, these are rural, sparsely inhabited areas; in a few cases (such as Notre-Dame-des-Anges and Saint-Louis-de-Gonzague-du-Cap-Tourmente), they are divisions created originally to give special municipal independence to certain church installations.
