Getty moved Kowalski to his third cabinet portfolio, the Ministry of Public Works, Supply, and Services. He kept that portfolio when Ralph Klein became Premier in 1992 and also became Deputy Premier. He held both those portfolios going into the 1993 general election. The electoral district of Barrhead was redistributed and became Barrhead-Westlock. He won the new electoral district with his highest popular vote to date in the face of a strong challenge from Liberal candidate Dale Greig and four other candidates.
