Number of seats won by major parties at each election
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, but the Lieutenant Governor is able to call one at any time, 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.
The table below shows the total number of seats won by each political party in each election. Full details on any election are linked via the year of the election at the start of the row, and details for the legislature that followed the election are available at the legislature number.
