Leonard Christian Halmrast (October 10, 1899 – February 7, 1979) was a politician from Alberta, Canada. He served in the Legislative Assembly of Alberta from 1945 to 1967 as a member of the Social Credit caucus in government. He held various portfolios in the cabinet of Premier Ernest Manning from 1953 to 1967.
Halmrast first ran for a seat to the Alberta Legislature as a Social Credit candidate in a by-election held in the electoral district of Warner on August 6, 1945. He defeated H.J. Hierath, who ran as a Single Tax candidate, in a landslide to hold the seat for his party.[1]
In the 1948 general election Halmrast defeated Liberal candidate William Colliton in a two-way race.[2]
In the 1952 general election Halmrast defeated Liberal candidate George Snow by a landslide in his third two-way race in a row.[3]
Premier Ernest Manning appointed Halmrast to his cabinet in 1953. Halmrast served as Minister of Public Welfare until January 5, 1954; he was then appointed Minister of Agriculture.
In the 1955 general election Halmrast defeated Liberal candidate J.L. Evans by a smaller margin than in earlier elections.[4]
In the 1959 general election Halmrast defeated Liberal candidate Mark Stringam in his fifth consecutive straight fight.[5]
On October 15, 1962, Premier Manning shuffled Halmrast back to the Public Welfare portfolio.
Redistribution in 1963 saw the electoral district of Warner merged with Taber to become Taber-Warner. In the election held that year Halmrast was returned to office by acclamation.[6] This was the last time that a candidate was elected unopposed to the Alberta legislature.
Halmrast retired from the assembly at dissolution in 1967.
