Argenteuil County is an historic county in southwestern Québec, Canada. It was located on the Ottawa River between Gatineau and Montréal. The county seat was Lachute. Argenteuil was bounded on the north by Terrebonne County, on the east by Deux-Montagnes County, on the west by Papineau County and on the south by the United Counties of Prescott and Russell in Ontario.

In the early 1980s the Quebec's counties were abolished and most of Argenteuil County became the Argenteuil Regional County Municipality in the Laurentides region. The northwestern corner was transferred to Les Laurentides Regional County Municipality the northern parts to Les Pays-d'en-Haut Regional County Municipality and some eastern parts to Deux-Montagnes Regional County Municipality.


Lovell's Gazetteer (1895)

  • "ARGENTEUIL, a county of Quebec, situated in that part of the Province which comprises the Lower Ottawa valley. Area 467,116 acres. The Ottawa River washes about 30 miles of its border, and forms its southern boundary. It is watered by the Rouge and North Rivers, and several smaller streams. On the east and north it is bounded by the counties of Two Mountains, Terreboune and Montcalm; and on the west by Ottawa county. The famous Laurentian mountain range traverses the heart of the county from east to west, and the rich mineral deposits of this range assure a future of great prosperity and wealth to the fortunate possessor of lands in the neighborhood. The county was, at the last census, inhabited by a population of something over 15,158. Fully two-thirds of these are English-speaking persons, settlers and descendants of settlers from Great Britain and Ireland; about a third of the people are French-Canadians. The county is rich in pasture lands, and is well adapted for dairy operations. Possibly the time is not distant when its immense water power and its mineral deposits will be more fully developed. In the present an industrious settler can derive a very comfortable subsistence from the pursuit of agriculture or dairy farming; most of the people are in comfortable circumstances, while not a few of the older farmers are undoubtedly men of wealth. The county is reached from Montreal (in the summer months) by the steamers plying on the Ottawa River, the point of debarkation being Carillon, in St. Andrews parish, and the foot of the rapids, which are overcome by those costly public works, the Grenville and Carillon canals. Since the line of the C, P. R. has traversed the county, Argenteuil has enjoyed communication with Montreal and Ottawa by several trains each way daily. Chief town, Lachute. Pop. over 15,158."

French names for places

Because French is the one official language of Québec, WeRelate employs the French names for places within the province. Many placenames will be similar to their counterparts in English, with the addition of accents and hyphens between the words. The words "Saint" and "Sainte" should be spelled out in full. Placenames should be made up of four parts: the community (or parish, or township, or canton), the historic county, Québec, Canada. You may find placenames red-linked unless you follow these conventions.

Local government structure

The Province of Québec was made up of counties and territories. Counties in Québec were established gradually as the land was settled by Europeans. Each county included communities with some form of local governement (often church-based). Territories referred to the undeveloped sections under the control of the government in charge of the whole province at the time. The communities included townships and/or cantons, depending on the English/French makeup of the county concerned, and also included ecclesiastical parishes with somewhat different boundaries which could overlap with local townships or cantons. Ecclesiastical parish registers have been retained and are available to view (online through Ancestry). Since the 1980s many small townships and parishes are merging into larger "municipalities", often with the same name as one of their components.

Beginning in 1979 the historic counties of Québec were replaced by administrative regions and regional county municipalities (abbreviated as RCM in English and MRC in French). Regional county municipalities are a supra-local type of regional municipality, and act as the local municipality in unorganized territories within their borders. (An unorganized area or unorganized territory is any geographic region in Canada that does not form part of a municipality or Indian reserve. There is a list in Wikipedia.) There are also 18 equivalent territories (TEs) which are not considered to be RCMs. These are mostly large cities with their suburbs, but include 4 very large geographical areas where the population is sparse.

The administrative regions (above the RCMs in the hierarchy) are illustrated on a map in Wikipedia. The regions are used to organize the delivery of provincial government services and there are conferences of elected officers in each region. The regions existed before the change from historic counties to regional county municipalities.

The above description is based on various articles in Wikipedia including one titled Types of municipalities in Quebec

NOTE: WeRelate refers to Québec communities as being within their historic counties because this is the description which will be found in historical documents. FamilySearch and Quebec GenWeb follow the same procedure. However, it is always wise to know the current RCM as well in order to track these documents down in local repositories and also to describe events which have taken place since 1980.

Because the former or historic counties and the modern regional county municipalities can have the same names but may cover a slightly different geographical area, the placenames for Regional County Municipalities or "Territories Equivalent to regional county municipalities" are distinguished by including the abbreviation "RCM" or "TE" following the name.

Historic counties (which were taken out of use in about 1982) were made up of townships or cantons. The two words are equivalent in English and French. Eventually all the Québec cantons in WeRelate will be described as townships. Many townships disappeared before 1980 with the growth of urbanization.

If the word parish is used, this is the local ecclesiastical parish of the Roman Catholic Church. Parish boundaries and township or canton boundaries were not always the same.

The WeRelate standard form for expressing a place in Québec is township/canton/parish, historic county, Québec, Canada,
or local municipality, administrative region, Québec, Canada for places established after the changes of the 1980s.


Censuses were taken throughout the 19th century in Quebec (or in Lower Canada or Canada West before 1867). Surprisingly most of them have been archived and have been placed online free of charge by the Government of Canada (both microfilmed images and transcriptions). All can be searched by name or browsed by electoral district. The contents vary. Those of 1825, 1831 and 1841 record only the householders by name, but remaining members of each household were counted by sex and by age range. From 1851 through 1911 each individual was named and described separately. The amount of information increased throughout the century, and in 1891 people were asked for their birthdate and the year of immigration to Canada. Unfortunately, enumerators were required only to record the birthplace province or country (if an immigrant). Specific birthplaces have to be discovered elsewhere.

The links below are to the introductory page for the specific census year. It is wise to read through this page first to see what will be provided on a specific census, and what will be lacking. Links to the records follow from these pages.

The 1921 census is available through and is also free of charge.
