It contained the community of Malton which had its beginnings about 1820. The village was named for Malton, North Yorkshire, by a local settler Richard Halliday. Lester B Pearson International Airport, originally named Malton Airport, is located not far north of the original village.

Toronto Gore came into existence as a township in 1831 when it was separated from Chinguacousy Township. In 1867 it became part of Peel County when that county was split from York County. A small wedge-shaped tract of land, Toronto Gore was located on the east of the county, on the border with York. It was south of Albion Township, east of Chinguacousy Township, and northeast of Toronto Township. Later, the southern portion of the township was annexed to Toronto Township, and finally in 1973 the remainder was incorporated into the City of Brampton.
Several historical villages were once located within Toronto Gore, including Claireville, Ebenezer, Castlemore, Wildfield and Colerane. However, only small remnants like churches and cemeteries of these former villages exist. Wildfield remains the only community to maintain its unique identity while the rest have been completely overtaken by suburban developments.
A diagramatic map in Wikipedia shows the location of the five orginal townships and another diagrammatic map illustrates the new divisions of Peel. It is assumed that the division between the north and south parts of Toronto Gore was a line extending the boundary between Chinguacousy and Toronto Townships.
The map of Peel County circa 1951 from Ontario Archives locates the individual towns and villages.
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.
