The Legislature of Alberta is the unicameral legislature of the province of Alberta, Canada. The legislature is made of two elements: the Lieutenant Governor of Alberta, and the Legislative Assembly of Alberta. The legislature has existed since Alberta was formed out of part of the North-West Territories in 1905. Like the Canadian federal government, Alberta uses a Westminster-style parliamentary government, in which members are sent to the Legislative Assembly after general elections and the lieutenant governor appoints the person who can command a majority of the members of the Assembly, typically the leader of the party with the most seats, as Premier of Alberta. The premier then recommends the appointment of the Executive Council of Alberta. The premier is Alberta's head of government, while the King of Canada is its head of state.
