 Under Alberta's fixed-election legislation of 2011, a general election is to be held on a day (by custom, a Monday) between March 1 and May 31 in the 4th calendar year following the most recent general election, but the premier can bindingly advise the lieutenant governor to call an election earlier than the fixed date.An election may also happen if the governing party loses the confidence of the legislature, by the defeat of a supply bill or tabling of a confidence motion, but in Alberta's history of massive majorities in the assembly, this has not happened yet in the province's history.
