In 1967, the Victorian mansion that once stood at 345 Laurier Avenue East was demolished. Shortly after, apartment buildings were built on the property which are still standing today. Currently there is no commemorative plaque to acknowledge the work that went on in Sandy Hill during World War II. While some community groups have hopes of one day creating some form of monument for the Examination Unit, there are no plans in the immediate future.
Upon victory, the Examination Unit experienced a metamorphosis of sorts. The Examination Unit and the Discrimination Unit, who once shared the 345 Laurier Avenue office, were "“merged into a single integrated SIGINT service” which was named “the Communications Branch of the National Research Council” [1]. The Discrimination unit focused on “signal collection” throughout the war rather than “decryption and evaluation” [1]. Although some have argued that more could have been done for the war effort had the units been merged all along.
In addition to this new and improved National Research Council, more organizations formed to help secure Canada's footing on the world stage of intelligence operations including “the Canadian Joint Intelligence Committee (CJIC), the Canadian Joint Intelligence Bureau, and the Canadian Joint Intelligence Staff”[1].
After the war the Canadian government began to deny the existence of a Canadian communications intelligence capability. It did so well into the late 1970s. In 1979 senior cabinet members were still kept in the dark on CSEC affairs. [2]
In 1984 the story of Canadian wartime intelligence operations first appeared in scholarly journal. In response, a historian at Department of External Affairs requested to publish his account of the same events that year, but was refused because the Canadian government still considered all of its wartime work classified. A court case went to the supreme court that same year which the forced the Canadian government to open up about its war time activities in the same ways that the British and Americans had done. [3]
In march 1986 after more information became available, a sensation Ottawa news headline “Japanese cables could have provided advance warning of Pearl Harbour”. [3] Since then various historians have looked into Canada's communications past, but there is still little recognition. Many Canadians still do not know what took place at 345 Laurier.
