Following the resignation of William Vander Zalm, Rita Johnston was appointed as the Premier of British Columbia, making her the first female premier in Canadian history. Johnston, who had been an active member of the Social Credit Party, had held several key ministerial positions, including Minister of Advanced Education and Job Training. Her rise to power was influenced by Vander Zalm's departure amid controversies and growing public dissatisfaction, creating an urgent need for new leadership in the province. Johnston took office in a time of economic turmoil, with the province facing budget deficits, rising unemployment, and significant public sector challenges.

During her premiership, Johnston focused on trying to stabilize the economy and address issues within the provincial government. She emphasized fiscal responsibility and aimed to restore public confidence in the government’s ability to manage provincial affairs effectively. Johnston faced numerous challenges, including opposition from both within her party and the rival New Democratic Party (NDP). Her term lasted until the provincial election later that year, wherein she led her party into a difficult election campaign.

Johnston's leadership was both praised and criticized; she became a symbol of progress for women in politics but was also subject to scrutiny regarding her policies and decisions. The outcomes of her tenure would shape the trajectory of female involvement in Canadian provincial politics long after she left office, setting a precedent for future generations of women leaders.
