Middlesex County is located in southwestern Ontario, Canada. It is a rural county with a very large city, London, within it. Landlocked, the county is bordered by Huron and Perth Counties on the north, Oxford County on the east, Elgin County on the south, and Lambton County and the former Kent County (now Chatham-Kent) on the west.

In 2011 the population of the county including the City of London was nearly 440,000. London is politically independent from the county, but is the location of the county governmental offices.

Prior to 1794 the land that was to become Middlesex County was an unbroken wilderness. Up until 1800 Middlesex County was known as Suffolk County and was part of Western District of Upper Canada. Middlesex County was established in 1800 and named for Middlesex, England. In 1800 the Western District was divided into two and Middlesex County became part of the London District. The District form of administration was abolished in favour of the county system in 1849-50.

Settlement started along the Thames River, with the first settlement in Delaware Township. Until 1852 the area that is now Elgin County was part of Middlesex County. In 1865 the townships of Biddulph and McGillivray, previously in Huron County were transferred to Middlesex County.

The population grew from under 40,000 in 1852 to almost 320,000 in 1980.


Following a reorganization of municipalities in 2001, Middlesex County is composed of eight incorporated municipalities and three First Nations reserves:

First Nations reserves:

  • Chippewas of the Thames 42
  • Munsee-Delaware 1
  • Oneida 41

and the City of London which is politically independent, but geographically within, from Middlesex County.

The map of Middlesex County circa 1951 from Ontario Archives locates the individual townships, city, towns and villages of the county. (Click at the bottom of the page to see the map enlarged.)

A sketchmap from Ontario GenWeb provides a simple illustration of the location of the townships.

Research Tips

The primary source for basic documents (vital statistics, land records, wills) for people who lived in the Province of Ontario is the Archives of Ontario, 134 Ian Macdonald Blvd, Toronto, Ontario, Canada M7A 2C5.

Early Records

Civil registration did not begin in the province until 1869. Before then there may be church records of baptisms and burials. For the most part these are still held by the denomination who recorded them. Copies of marriage records made pre-1869 had to be sent by individual clergymen to the registrar of the county in which the marriage took place. These marriage records are available through Ontario Archives, on micorfilm through LDS libraries, and on paid and unpaid websites, but because they were copied at the registrars' offices, they cannot be considered a primary source.

Vital Records after 1869

Birth, marriage and death registrations are not open to the public until a specific number of years after the event occurred. Births to 1915 are now available [October 2014]; dates for marriages and deaths are later. Birth and death registration was not universally carried out in the early years after its adoption. Deaths were more apt to be reported than births for several years. The more rural the area, the less likely it would be that these happenings were reported to the authorities.
Images and indexes of civil registrations for the "viewable" years can be found on paid websites, and indexes only on FamilySearch. The FamilySearch Wiki on Ontario Vital Records explains how these records are organized and their availability.
In September 2014 announced that its paid website has been subjected to a "houseclean" of its Ontario BMD database, adding data that had been omitted and making many corrections. Its provision now includes

  • Births, with 2,172,124 records covering 1869-1913.
  • Marriages, with 3,393,369 records for 1801-1928 including Ontario county, district and Roman Catholic origins as well as province-wide civil registration.
  • Deaths, with 2,190,030 records comprising Ontario civil registrations of deaths, 1869-1938 and registrations of Ontario overseas deaths for 1939-1947.

Land Records and Wills

Information on how to access land records and wills is best sought on the Archives of Ontario website. An ancestor's land holding might be found on Canadian County Atlas Digital Project if he was in occupancy circa 1878.

The original censuses are in the hands of Library and Archives Canada, known to Canadians as "LAC". Copies of original microfilms are online at the LAC website for all censuses up to 1921. Each census database is preceded with an explanation of the geographical area covered, the amount of material retained (some census division material has been lost), the questions on the census form, and whether there is a name index. Census divisions were redrawn as the population increased and more land was inhabited.
Other websites, some paid and some free, also provide Canadian census originals and/or indexes online. One can also view censuses on microfilm at the LAC, at the Archives of Ontario (see address above), or at large libraries throughout Canada.

Websites with more local information on Middlesex County

  • Middlesex GenWeb has short "biographies" of each of the townships and a database of all the cemeteries in Middlesex, complete with street addresses for all and GPS co-ordinates for some. This is part of a province-wide project to provide cemetery information. There is also a link to completed and incomplete census transcriptions on a township by township basis.
