Single-tier municipality (Canada)

In the Canadian Republic, most small to medium-sized communities have been incorporated as municipalities (French: municipalités; sg. municipalité) of the single-tier form (mode palier-unique), either as independent single-tier municipalities, often rural (municipalités de palier-unique) or one of several lower-tier municipalities (municipalités de palier-inférieur) within an upper-tier municipality (municipalité de palier-supérieur). The most common form of upper-tier municipality is a county, although several upper-tier municipalities, especially urban ones, go by other titles, such as "regional district" (district régional) or "regional municipality" (municipalité régional), among others.
