[2] The C Int C was never disbanded; however, it was effectively reduced to nil strength at Unification, and entered an administrative hibernation with its personnel and duties assigned to the new Security Branch.

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.

The material allowed Ottawa to carry on a completely free exchange of communications by direct signal link with the Tracking Room in the Operational Intelligence Centre (OIC).

The results were such that, "Canadian...intercept stations and Direction Finding (DF) organizations...made an indispensable contribution to the Allied North Atlantic SIGINT network."

Intelligence operations continued in this theatre until all of the "Canadian Mediterranean Force moved to Belgium in 1945" and then went back "into action in Holland."

They studied the role the Canadians were to play and assisted in the collation of the voluminous amounts of Intelligence detail, which poured into London from every conceivable source.

Details concerning German Troop Strength, their defences, their armaments, administrative and supply systems, general strengths, dispositions, state of morale, fighting ability, personality studies concerning characteristics of enemy commanders, the German military state of preparedness, and reinforcement capabilities.

Many C Int C personnel went into Europe with the "3rd Canadian Infantry Division (3 Cdn Inf Div) under I British Corps" when it "landed in Normandy on D-Day."

The Department of National Defence – Army - issued an order from Ottawa on 6 November 1942, granting authority, effective 29 October 1942, for the formation of a Canadian Intelligence Corps.

In the Brigade-sized combined Canada-United States First Special Service Force (FSSF), which operated in Kiska and in Italy for example, the Unit Intelligence Officer was Major R.D.

Once the Canadian Army was "firmly established in France," its Intelligence Corps personnel made good use of "the principles they had learned in England, North Africa, Sicily and Italy."

Caches of explosives that had been prepared and stored or set in place to destroy key points, facilities, infrastructure, personnel, and equipment, were retrieved from underground storage vaults and rendered harmless.

The Intelligence gleaned by C Int C staffs enabled them to gain an accurate indication of changes in the identity of enemy formations facing them.

The Germans launched an offensive in the Ardennes, with the object of seizing the River Meuse and the capture of Liege to prevent the Allies from mounting an attack in the Aachen sector.

Scattered along the length of the Lower Maas, from Nijmegen in the East to Walcheren Island in the West, elements of the Canadian Army were deployed to guard the Allies' northern flank.

Enemy activity along the north bank of the Lower Maas involved mass movement of formations, the erection of rafting sites and barges, and vast numbers of recently positioned gun emplacements were clear indications to Intelligence that an attack from this direction, combined with the one already in progress in the Ardennes, was imminent.

As a result, formations of the Canadian Units were re-deployed to meet the attack, which was later revealed to have been directed at Antwerp but cancelled due to the failure of German forces in the Ardennes to reach their objectives.

Similar activity took place "in Holland where large German forces whose escape to Germany had been cut off by the Canadians were "screened."

According to U.S. Army Col Murray Sanders, a highly qualified bacteriologist with the U.S. Chemical Warfare Service (CWS) at Camp Detrick in Maryland, "the cooperation [with Britain and Canada], the sharing of discovery and conjecture was total...we were more cautious with the French and we told the Soviets nothing."

Many of its members had been seconded to British and American organizations and were employed in a wide variety of activities including clandestine operations in Europe and Asia.

Although the Corps was technically in administrative hibernation from 1968 until 2016, the function of delivering intelligence support to the Canadian Army in the field continued.

Given its connection with the Canadian Corps Cyclist Battalion, the Headquarters of the C Int C commemorates the Battle of Amiens annually on 8 August.
