Uxbridge Township was first established within York County in the Home District of Upper Canada and received its first settlers in 1806. It became a township in Ontario County when that county was founded in 1852. In the provincial reorganzation of county structure in 1974, it merged with Scott Township, its neighbouring township to the north, and is now found in the Regional Municipality of Durham.
The original settlers were Quakers and a Friends Meeting House was built in 1820.
Uxbridge now has the third largest geographic area (more than 40,000 hectares) of the eight municipalities which form the Regional Municipality of Durham. However, it is the second smallest municipality in the Region with a population of just over 20,000 in 2011.
This drawing from Wikipedia shows the new municipality of Uxbridge adjacent to the other municipalities of Durham Region. It can be compared with a similar map from Ontario GenWeb illustrating Ontario County prior to 1974.
The main centre in the township is the namesake community of Uxbridge. Other communities within the township include Coppins Corners, Goodwood, Leaskdale, Roseville, Sandford, Siloam, Victoria Corners and Zephyr.
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.
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.
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 1911. 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. The 1921 census is only available through Ancestry.ca, but it is free-to-view.
