He served in the Social Cr government in several posts including Minister of State for the Northeast and Nechako, Minister of Energy, Mines and Petroleum Resources, and as British Columbia"s first Minister of Native Affairs. Weisgerber became interim leader of the party. British Columbia Reform, as it was known, espoused similar policies to the Reform Party of Canada, but was a separate entity.
Weisgerber ran for the British Columbia Reform leadership and was elected party leader in late 1994.
A split in the centre-right vote between Weisgerber"s British Columbia Reform Party and Gordon Campbell"s Liberals is cited as a factor for the New Democratic Party winning the 1996 British Columbia election. Weisgerber resigned as British Columbia Reform"s leader in late 1996, and was replaced by Wilf Hanni in September 1997.
Weisgerber served out his third and final term in the British Columbia legislature. Shortly before the 2001 election, Weisgerber endorsed the British Columbia Liberal Party and its leader, Gordon Campbell.
He was appointed by the British Columbia Liberal government to be a director for the state-run provincial power utility, British Columbia Hydro, on September 25, 2001.
He is a Commissioner of the British Columbia Treaty Commission.
