Commission de toponymie of Québec


The Commission de toponymie of Québec is the public body responsible for managing Québec place names : names of natural geographical features (lakes, rivers, mountains, islands, peninsulas, etc.) and constructed ones (dams, embankments, bridges, etc.); and names of administrative units (wildlife sanctuaries, administrative regions, conservation parks, etc.), inhabited areas (cities and towns, village municipalities, Indian reserves, northern village municipalities, etc.) and roadways (streets, roads, boulevards, range roads, etc.). In short, the Commission has jurisdiction regarding all types of places.

Since 1977, the Commission de toponymie has had the jurisdiction defined in the Charter of the French language, which also lists the Commission’s powers and duties. Briefly, the Commission must catalogue, preserve, officialize and publicize Québec place names. It can advise the government and other agencies of the civil administration on any question relating to toponymy and give names to places that do not have them yet, subject to the jurisdiction that other authorities have over place names.

It was back in 1912 that a Québec public body was first given the mission of managing the names of places in Québec. This management must take into account both the territorial and the cultural aspects of toponymy, aspects which are complementary and reflect the multidisciplinary nature of the field. Not only must the location and the nature of places be expressed as rigorously as possible, but the measures required to preserve and showcase our place name heritage, which is part of our national identity, must also be taken into account. The implementation of the Charter of the French language, supported by a body of policies and standards on the choice and written form of place names, has brought about a sustained emergence of the French face of Québec toponymy for more than a quarter of a century now.

The Commission has been disseminating its acquired expertise for some nine decades, through participation in United Nations work on the standardization of geographical names, through participation in the work of the Geographical Names Board of Canada and through bilateral relations with a certain number of countries—especially France—thereby ensuring that its mission has a significant impact beyond Québec’s borders.

Place name search

The mandate of the Commission de toponymie of Québec, which is defined by the Charter of the French language, includes, principally, the cataloguing, processing and officialization of place names, the publicization of official place names among those who use them, and the preservation of place names in a data bank. The latter, known as Banque de noms de lieux du Québec, is updated monthly and provides accurate information on more than 255 500 names of places in Québec. Location maps to various scales are appended to responses to toponym queries, with the exception of odonym queries (regarding names of roadways).

In addition, for more than 22 000 place names, the meaning of the name is included on the fact sheet just below the map. An asterisk in the search results list indicates that the information exists and is accessible for the name concerned.

Simple search : Recherche
