1st (Western Ontario) Battalion
1st Canadian Division
Frederic William Hill was the first 1st Battalion CO, from September 1914 to January 1916, when he was promoted to command the 9th Infantry Brigade.
Frank A. Creighton succeeded Hill in command of the 1st Battalion in January 1916. He was killed when a shell hit his headquarters on 15 June 1916.
Former 9th Canadian Mounted Rifles CO, George C. Hodson was next selected to take command of the 1st Battalion. The appointment of an outsider caused friction with other officers. He was sacked on 16 August 1917.
Albert Sparling, who earned a D.S.O. and Bar, commanded the 1st Battalion from 17 August 1917 until the end of the war.
