Canadian diplomat Pierre Dupuy was named Commissioner General, after Diefenbaker appointee Paul Bienvenu resigned from the post in 1963. One of the main responsibilities of the Commissioner General was to attract other nations to build pavilions at Expo. Dupuy would spend most of 1964 and 1965 soliciting 125 countries, spending more time abroad than in Canada. Dupuy's 'right-hand' man was Robert Fletcher Shaw, the deputy commissioner general and vice-president of the corporation. He also replaced a Diefenbaker appointee, C.F. Carsley, Deputy Commissioner General. Shaw was a professional engineer and builder, and is widely credited for the total building of the Exhibition. Dupuy hired Andrew Kniewasser as the general manager. The management group became known as "Les Durs"—the tough guys—and they were in charge of creating, building and managing Expo. "Les Durs" consisted of: Jean-Claude Delorme, Legal Counsel and Secretary of the Corporation; Dale Rediker, Director of Finances; Colonel Edward Churchill, Director of Installations; Philippe de Gaspé Beaubien, Director of Operations, dubbed "The Mayor of Expo"; Pierre de Bellefeuille, Director of Exhibitors; and Yves Jasmin, Director of Information, Advertising and Public Relations. To this group the chief architect Édouard Fiset was added. All ten were honoured by the Canadian government as recipients of the Order of Canada, Companions for Dupuy and Shaw, Officers for the others.
