William A. McGillivray

McGillivray was admitted to the Alberta bar on June 23, 1942 and the Saskatchewan bar in 1965, and practiced in Calgary. He served as Bencher of the Law Society of Alberta from 1958–1969, and then as its President from 1969–1970, becoming Queen's Counsel on December 31, 1957. He practiced in Calgary with the law firm of Fenerty, McGillivray, Robertson, Prowse, Brennan, Fraser and Bell.^[2]

In 1974, McGillivray was appointed directly to the position of Chief Justice of Alberta and was therefore, like his father, a justice of the Supreme Court of Alberta Appellate Division. Once on the bench, he was known for writing many reported criminal law judgments. He served in this position until his death in 1984. During that time, he also served concurrently as Chief Justice of the Northwest Territories.

His son, Douglas A. McGillivray, K.C. was also President of the Law Society of Alberta from 2005-2006.^[3]
