Lansdowne was a rural constituency in the province's southwestern corner. For almost its entire history, it was considered safe for the Liberal Party and its successor, the Liberal-Progressive Party. Only two non-Liberals were ever elected for the division, and both were defeated after a single term. Tobias Norris, who served as Premier of Manitoba from 1915 to 1922, represented Lansdowne in the provincial legislature for twenty-one years.
After its elimination, parts of Lansdowne were included in the new constituency of Souris-Lansdowne.
