Banff in Canada conducted a bid campaign for the host city for the XI Olympic Winter Games in 1972, but Banff did not acquire the hosting rights. According to previous studies, the Calgary Olympic Development Association（CODA）, the candidate committee for Banff, and the Canadian Olympic Association（COA）, the National Olympic Committee in Canada, were subjected to protests by environmental groups and naturalists regarding construction of the facilities. Avery Brundage, president of the International Olympic Committee（IOC）, was concerned about this situation. On the other hand, In Sapporo which was the host city, Brundage and the organizing committee in Sapporo had underwater negotiations on the request for environmentalists to change the stadium after deciding the host city.
The purpose of this study is to clarify the negotiations between Brundage with Edger Davis, the president of CODA, and James Worrall, the president of COA, concerning the construction of facilities and nature conservation in Banff.
The results of this study are summarized as follows:
Davis informed Brundage that CODA created opportunities for discussions with environmental groups and naturalists to reject protests of them. Davis and Worrall argued Brundage that naturalists exaggerated to the effects on the environment.
Brundage showed some understanding concerning measures by CODA and COA. However, he again received protests. He was concerned about protests during the Games. Therefore, he informed Worrall that he reported the existence of protests concerning Banff's candidacy in a meeting of IOC.
Worrall accepted the existence of protests by environmental groups and naturalists concerning Banff's candidacy. Nevertheless, he regarded the protest movements as a minority opinion and argued against them with support from the Canadian government.
