It was announced on 5 August 1926 that George V had, by commission under the royal sign-manual and signet, approved the recommendation of his British prime minister, Stanley Baldwin, to appoint Willingdon as his representative in Canada. The sitting Conservative British Cabinet had initially not considered Willingdon as a candidate for the governor generalcy, as he was seen to have less of the necessary knowledge of affairs and public appeal that other individuals held. However, the King himself put forward Willingdon's name for inclusion in the list sent to Canada, and it was that name that the then Canadian prime minister, William Lyon Mackenzie King, chose as his preference for the nomination to the King. George V readily accepted, and Willingdon was notified of his appointment while on a diplomatic mission in China.
