When she was just fifteen (see Photography and Travels) Montgomery met Prime Minister Sir John A. and Lady Macdonald. When she was fifty-nine, she was awarded the Order of the British Empire by King George V of England. In between these two times, Montgomery enjoyed much public attention through readings and teas, dinners, and presentations made in her honor or to which she was specially invited. Several pages of her scrapbook are devoted to her meeting in September 1910 with Earl Grey and Lady Grey when they were on an official cross-Canada trip. In 1927 she was presented to British Prime Minister Stanley Baldwin (at his request, because of his love for Anne of Green Gables) and the Prince of Wales.

She chronicled some of the social affairs of heads of state through clippings in her scrapbooks. For example, she pasted in a post card of the lying in state of King Edward VII, and shared in her journal and letters to MacMillan her indignation over the abdication of Edward the VIII.
