In 1947, the King issued letters patent granting his Canadian governor general permission to exercise all those powers belonging to the monarch in respect of Canada and, at the Commonwealth Prime Ministers Conference of 1949, the decision was reached to use the term "member of the Commonwealth" instead of "Dominion" to refer to the non-British member states of the Commonwealth of Nations. That same year, Alexander oversaw the admission of the British crown colony of Newfoundland into Canadian Confederation and toured the new province that summer. Then, during a later visit to Alberta, the Governor General was admitted to the Blackfoot tribe as Chief Eagle Head. However, though the post-war period saw a boom in prosperity for Canada, the country was again at war by 1950, with Alexander, in his role as acting commander-in-chief, deploying to the Korean War soldiers, sailors, and airmen, whom he would visit prior to their departure for north-east Asia.
