The Canadian province of Alberta holds elections to its unicameral legislative body, the Legislative Assembly of Alberta. 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.[3] However, the Premier has typically asked the Lieutenant Governor to call the election in the fourth or fifth year after the preceding election. The number of seats has increased over time, from 25 for the first election in 1905, to the current 87.

Alberta's politics has historically been one of long-lasting governments with government changes being few and far between. The province from 1905 to 2015 was ruled by four "dynasties": the Liberal Party (1905–1921); the United Farmers of Alberta (1921–1935), the Social Credit Party (1935–1971), and the Progressive Conservative (PC) Association (1971–2015), the longest political dynasty in Canada. No minority government has ever been elected. 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.

In 2015, the NDP were elected to government for the first time in Alberta's history. The NDP had Alberta's only one term government thus far.

In 2019 the newly formed United Conservative Party formed the government.

Before 1924, most Alberta elections used a combination of single-member and multi-member districts, plurality being enough to be elected. From 1924 to 1955, Alberta used Ranked voting where a mixture of proportional representation (single transferable voting) and Instant-runoff voting was used. Since 1956, Alberta's elections have used single-member plurality also known as first past the post.[4]

Electoral system

Alberta has used a variety of electoral systems in its history, notably a combination of single transferable vote (STV) and instant-runoff voting (IRV) for nearly four decades.

Electoral system of Alberta

1905 First past the post
1909 Double-member plurality-at-large First past the post
1913 Double-member First past the post
1917 First past the post
1921 Five-member plurality-at-large Double-member First past the post

1959–present First past the post

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. Voting in these multi-member districts was by Block Voting.

Each was broken up into three single-member districts by 1917, as the overall number of districts increased rapidly. As well 1917 saw two other innovations - election of two MLAs by soldiers and nurses overseas; and automatic re-election of 11 MLAs who were serving in the armed forces.

The Liberal government introduced five-member block voting constituencies in Edmonton and Calgary in 1921, and briefly made Medicine Hat a two-member district. Each voter in the cities was given five votes,in Medicine Hat two votes. The Liberal party led the vote in Edmonton (although not taking a majority of the city vote) and its candidates received many multiple votes, together taking more votes than the number of Edmontonians who voted. It won all five of Edmonton's seats. The United Farmers won many rural seats and formed government.[10][11]

The UFA government, which had campaigned on a promise of electoral reform, retained the existing multi-seat districts and adopted single transferable vote in Edmonton, Calgary and Medicine Hat. Instant-runoff voting (IRV) (AKA Alternative Voting) was put into use elsewhere. STV in Edmonton and Calgary produced mixed roughly proportional results in the election of city MLAs.[12]

IRV elsewhere had little impact as the UFA candidates were extremely popular, usually taking a majority of the vote. This would be the pattern for the next two decades with the governing party (UFA then Social Credit) taking a majority of the rural seats, and STV in the cities giving each party its proportion of the city seats. These parallel systems, STV in the cities and IRV in the rest of the province, were used for eight elections over three decades.

During these eight elections the only modifications made were that Albertans serving in armed fores in 1944 elected three armed force representatives, one for each branch - army, navy and air force; M.H. was changed to a single-member district prior to the 1930 election; and the number of MLAs sitting for Edmonton and Calgary changed over time.[13]

Until recently, the pattern has been for one party to take a majority of the seats outside the cities, usually by a majority of the vote in the first count. Due to the relative small number of seats in the cities, that ensured the party's ascendancy to power. The UFA did not, but the SC and Conservative governments usually took a fair number of city seats as well as most of the rural seats. 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. In these districts a SC candidate led in the first count but did not take a majority of the vote and each lost out when votes were transferred as per IRV. [14]

Following this turn of events, Ernest Manning's Social Credit government abolished the mixed STV/IRV system, without public consultations or a referendum. The city-wide districts in Edmonton and Calgary were broken up and single-member districts were created, and the use of transferable votes was ended. The government reintroduced first past the post across the province. The SC government reaped a windfall of seats in the 1959 election.[15]

First past the post remains the system used in Alberta and throughout Canada for provincial and federal elections.[16]
