When John Diefenbaker took office as Prime Minister of Canada on June 21, 1957, only one Progressive Conservative MP, Earl Rowe, had served in federal governmental office, for a brief period under Bennett in 1935. Rowe was no friend of Diefenbaker — he had briefly served as the party's acting leader in-between Drew's resignation and Diefenbaker's election, and did not definitively rule himself out of running to succeed Drew permanently until a relatively late stage, contributing to Diefenbaker's mistrust of him — and was given no place in his government. Diefenbaker appointed Ellen Fairclough as Secretary of State for Canada, the first woman to be appointed to a Cabinet post, and Michael Starr as Minister of Labour, the first Canadian of Ukrainian descent to serve in Cabinet.
