Halldorson worked as a teacher of languages, teaching Latin, French and German from 1918 to 1938 at Jon Bjarnason Academy,[4] a private school started by the Icelandic Lutheran Church in 1913.
The Social Credit League won only five seats (out of 55) in this election, but held the balance of power by maintaining John Bracken's Liberal-Progressive government in office.
In 1940, the party formally entered an all-party coalition government with the Liberal-Progressives, Conservatives and Cooperative Commonwealth Federation.
Social Credit split on the coalition issue, and Halldorson broke with the rest of her caucus to serve as the legislature's second opposition member.
[1] In addition to her career in the legislature, Halldorson served as vice-president and president of the Manitoba Social Credit League in the 1930s and 1940s.
