Riverside is a neighbourhood on the eastern edge of Windsor, Ontario. It is best defined by the waterfront road, Riverside Drive, which runs parallel to the Detroit River. The western boundary is approximately Westminster Boulevard running easterly to Rendezvous Shores and the Windsor/Tecumseh town line. That town line is formally defined by a drainage ditch to the Eastern side of the Rendezvous property. Rendezvous Shores is a recent development on the lands which were a large grass field between a marine basin and the Rendezvous Tavern, the Tavern was approximately 1150feet south from the Lake St. Clair shore and the marine basin, while the adjoining properties were a maximum 800feet, thus the marine basin jutted out into the southwest corner of Lake St. Clair. Most of the structure was break wall which was later landfilled to the east, and on most marine charts is referred to as Askin's Point. Riverside was a town until annexed by Windsor on Jan. 1, 1966. It truly extends all the way to Tecumseh to the East but that 3 mile stretch along Riverside Dr. of waterfront property and farms, is what would retrospectively be called a Hamlet in the city plans.

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 1914 are now available [October 2012]; 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. All of the original census (1851-1911) images are online with the exception of that for 1861. Not all of them are indexed. Later censuses are not yet available. Census divisions were redrawn as the population increased and more land was inhabited.
