The 1st Canadian Division is an operational command and control formation of the Canadian Army, based at CFB Kingston. Formed in August 1914, the 1st Canadian Division was a formation of the Canadian Expeditionary Force. The division was initially made up from provisional battalions that were named after their province of origin but these titles were dropped before the division arrived in Britain on October 14, 1914. Following the war, the division was stood down only to be remobilized as a formation on 1 September 1939 as the 1st Canadian Infantry Division for service in the Second World War. The division was also reactivated twice during the Cold War. In 2010, the unit was reactivated for a third time to serve as headquarters unit of any division-level formation of the Canadian Army.
