2015 Alberta general election
29th general election of Alberta, Canada
The 2015 Alberta general election was held on May 5, following a request of Premier Jim Prentice to the Lieutenant Governor of Alberta Donald Ethell to dissolve the Legislative Assembly on April 7. This election elected members to the 29th Alberta Legislature. It was only the fourth time in provincial history that saw a change of governing party, and was the last provincial election for both the Alberta Progressive Conservative and Wildrose parties, which merged in 2017 to form the United Conservative Party (although each ran a token candidate in the 2019 election).
The provincial Election Act fixed the election date to a three-month period between March 1 and May 31 in the fourth calendar year after the preceding election day – in this case, April 23, 2012. However, the act does not affect the powers of the Lieutenant Governor to dissolve the Legislature before this period.
As a result of the election, the Alberta New Democratic Party (NDP) were elected to a majority government under leader Rachel Notley. The NDP formed government for the first time in Alberta history since the NDP's founding in the early 1960s.
The 2015 election is sometimes called the "Orange Chinook", a reference to the province's dramatic swing to the NDP, the NDP's orange colour and the weather shifts occasioned by strong Chinook winds that southern Alberta commonly experiences.
The NDP win ousted the PCs, who were reduced to third place in seats. Prentice resigned as PC leader and MLA for Calgary-Foothills on election night.
This brief starts where responsible research should: with the source description of “2015 Alberta general election” as 29th general election of Alberta, Canada. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as 29th general election of Alberta, Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jun 13, 2026. The linked authority identifier is Q4632914. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015, 2017, 2019 and 2012.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
