The Canadian Intelligence Corps (C INT C) was an administrative corps of the Canadian Army.

Many Canadians were active in the Intelligence field as early as 1939. Major John P. Page GSO3 (Intelligence) at CMHQ in Ottawa was tasked “to evaluate Intelligence and consider how to promote the idea that the Canadian Army should form its own Canadian Intelligence Corps (C Int C).” His proposals were initially refused or set aside and it was not until 29 October 1942, that Canadian Army Intelligence was officially recognized as a Corps.

The initial elements of the Intelligence Corps included the “Intelligence Sections at HQ 1st Canadian Army, 1st Canadian Corps; 1st, 2nd and 3rd Infantry Divisions, 5th Armoured Division; No. 1 and No. 2 Canadian Special Wireless Sections Type B; seven Field Security Sections (Army, Nos. 1,2,3,7,11,12); I9X at CMHQ“ and the Intelligence “Pool.” Additional field Units were in service in Canada, such as the “Security Intelligence Sections at the Districts.”

With the formation of the 1st Canadian Army in Europe on 6 April 1942 and 2nd Canadian Corps on 14 January 1943, additional Intelligence staff were required and in due course added to the Canadian military establishment. Intelligence staff duties at CMHQ also continued to expand, as it became the clearinghouse for all security-clearance cases initiated in Canada and investigated in Britain.

To facilitate cooperation “throughout the period of hostilities, personnel in the Canadian Intelligence Corps formed part of the Canadian Army Staff in Washington and worked in close co-operation with the Intelligence Staff of the United States War Department.” They were linguists for the most part, proficient in German, Japanese and many other foreign languages.

Canada’s Naval and Air Intelligence Staffs were equally busy fighting the war. Canadian Naval Intelligence officers studied German naval telecommunications, exchanging through 1943 for example, a daily U-boat Situation Report. (See John B. McDiarmid) Special Intelligence from the UK was also provided to Ottawa and Washington. The level of cooperation between the three nations and their Naval Intelligence (NI) organizations was extremely close and both the American and Canadian officers paid visits to the Senior British Naval Intelligence Officer. All three nations promulgated the processed information to ships and commands within their zone of control. The UK recorded that formal integration of the three nation’s NI staffs was never necessary, because the Anglo-American organization worked as one against the U-boat threat.
