List of Alberta general elections

The maximum period between general elections of the assembly is five years,[1][2] but the Lieutenant Governor is able to call one at any time.

Thus, Alberta can be said to have continuously had a dominant-party system for its entire political history, though the dominant party has changed over time.

Only Alberta and Manitoba have used a proportional representation system for any length of time in the history of Canada, although in both provinces it was applied only partially.

(5-7 members per city) Single Transferable Voting Jan 9-20 to 1948 Alberta's first election was fought in 25 single-member first past the post districts.

The Liberal government, like other Canadian jurisdictions at the time, introduced two-member constituencies in Edmonton and Calgary in 1909 to accommodate their population.

The Liberal government introduced five-member Block Voting constituencies in Edmonton and Calgary in 1921, and made the Medicine Hat into a two-member district.

[12][6] The UFA government, which had campaigned on a promise of electoral reform, retained the existing multi-seat districts and adopted Single Transferable Voting in Edmonton, Calgary and Medicine Hat.

STV in Edmonton and Calgary produced mixed roughly proportional results in the election of city MLAs.

Due to change to First past the post in the cities, the one-party ascendency was raised to higher level.

In 1955, the SC government was re-elected with a great majority of the seats but for the first time IRV changed the outcome in four districts.

[6] Following this turn of events, Ernest Manning's Social Credit government abolished the mixed STV/IRV system, without public consultations or a referendum.
