* Rita Johnston was actually the incumbent Premier at the time, though she was appointed to office after Premier William Vander Zalm resigned in 1991.

Catherine Callbeck is the only woman who was ever elected premier of a Canadian province. She served from 1993 to 1996.

Note: There have also been a few female third-party (usually the NDP) provincial leaders. However, in most cases these parties, and by extension their leaders, were never regarded as a serious threat to either the ruling party or official opposition.
