Thunder Bay is a city in, and the seat of, Thunder Bay District, Ontario, Canada. It is the most populous municipality in Northwestern Ontario with a population of 108,359 as of the Canada 2011 Census, and the second most populous in Northern Ontario after Greater Sudbury. The census metropolitan area of Thunder Bay has a population of 121,596, and consists of the city of Thunder Bay, the municipalities of Oliver Paipoonge and Neebing, the townships of Shuniah, Conmee, O'Connor, and Gillies, and the Fort William First Nation.
European settlement in the region began in the late 17th century with a French fur trading outpost on the banks of the Kaministiquia River. It grew into an important transportation hub with its port forming an important link in the shipping of grain and other products from western Canada, through the Great Lakes and the Saint Lawrence Seaway, to the east coast. Forestry and manufacturing played important roles in the city's economy. They have declined in recent years, but have been replaced by a "knowledge economy" based on medical research and education. Thunder Bay is the site of the Thunder Bay Regional Research Institute.
The city takes its name from the immense Thunder Bay at the head of Lake Superior, known on 18th-century French maps as Baie du Tonnerre (Bay of Thunder). The city is often referred to as the "Lakehead", or "Canadian Lakehead", because of its location at the end of Great Lakes navigation on the Canadian side of the border.
Fort William and Port Arthur were separate cities until 1970.
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.
