Militia
During the 19th century, Ontario men between 16 and 60 years of age served in reserve units of local militia organized by county. Men reporting for militia duty were listed on annual muster rolls. Militia units were organized on a county basis. This system was replaced in 1855 with an active volunteer militia. It became the basis for the Canadian army. Militia members fought in military actions such as the War of 1812, the 1837 Rebellion, and the Fenian Raid of 1867, but records are few.

South African War, 1899-1902

 * South African War, 1899-1902 - Service Files, Medals and Land Applications
 * The South African War (1899-1902) is a key event in the military history of Canada. It was the first time in its history that Canada dispatched troops to an overseas war. In October 1899, the tensions between Dutch South Africans, known as Boers, and British South Africans erupted into open warfare. The government of Canada eventually responded to the crisis by recruiting, equipping and transporting two contingents of volunteers to serve with the British forces in South Africa. The British War Office paid all other costs, including pay and return transport. Later contingents were financed completely by the British War Office, with the exception of one recruited and paid for by Lord Strathcona.
 * Canadians participated in nine important battles between the November 1899 arrival of the first contingent in South Africa, and the end of the war in May 1902.
 * A total of 7,368 Canadians and 12 Nursing Sisters served in South Africa. This database brings together three groups of records pertaining to the South African War: the service files, medal registers and land grant applications.
