Sir Frederick William Borden, KCMG PC (May 14, 1847 – January 6, 1917) was a Canadian politician. While he was the Minister for Militia and Defence, he was the father of the most famous Canadian casualty of the Second Boer War Harold Lothrop Borden. Historians credit him with creating and financing a modernised Canadian militia with a staff and medical, transport, and signals that proved important for allowing Canadian ground forces to deploy with their own support services as self-contained national contingents, albeit in an imperial framework. In this sense, he helped to create the foundations for the Canadian Expeditionary Force of 1914–1918.
