History of the Canadian Civil Defence College (CCDC)
The photo above is of Worthington Hall at the Civil Defence College in Arnprior ON. It is set up for a conference or a seminar probably sometime in the 1960s or early 1970s. That time frame is suggested by the ashtrays for smokers on the tables and the old EMO crest on the wall in the background. Alternatively a large scale map of the Ottawa area could be placed on the floor and an interactive demonstration exercise conducted for an audience of trainees seated on the surrounding platform illustrating how post nuclear attack re-entry / rescue operations would have been conducted. See below. That map is currently in the archives of the Carp Diefenbunker Cold War Museum, along with a sample of the icons that would have been used to illustrate features such as medical centres and traffic control posts.
