Charles Hamilton Mitchell, CB, CMG, DSO (1872-1941) was a Civil Engineer and an Intelligence Officer of the Canadian Armed Forces in World War I, with the rank of Brigadier-General.

His father, George Mitchell, was a clergyman and a graduate of Upper Canada College and the University of Toronto in mathematics.

After leaving that post, he set up a Toronto-based consulting firm in 1906 in partnership with his brother Percival, working largely in hydroelectric power plant construction.

When the Canadian Corps was formed in August 1915, Col. Mitchell was sent to its Headquarters as G.S.O.2 (Int), the senior Intelligence appointment in the CEF.

He returned to the Canadian Army in June 1919, having won numerous honours and decorations, including French, Belgian and Italian awards.

He was appointed to the Order of the Bath on June 3, 1918, while serving on the Headquarters of the General Staff of the British Army in Italy with the CEF.

His exemplary service record also lent him authority early in his term, when fully half the student population consisted of returning veterans.

In this time, the faculty grew from a student body of 772 in 1919 to 961 in 1940, despite rising academic standards and the effects of The Great Depression.
