When the President and 1^st Vice-President had to resign before completing their term, Percy Bourne assumed the responsibilities of National President. This was a significant event as he became the first black President of a PSAC component union. Brother Bourne was a radio operator employed by the Department of Transport (DOT) at the Montreal Airport. Involved in the Canadian Air Services Association (CASA), he participated in the merger meeting in November 1966, where he became Québec Regional Vice-President. He was a DTC delegate to the PSAC Founding Convention. At the 1969 UCTE convention, he was elected 2nd Vice-President of the Department of Transport Component (DTC). In his years as President, Percy Bourne raised important issues around the discrimination of women in the Superannuation Act. He also pointed out the problem of technological change and its effect on members as subordinate to machines. In 1972 members working on canals were transferred to the Department of Indian and Northern Affairs but maintained their membership in the UCTE.
