[7] In 1937, the UFA decided to leave electoral politics entirely and, in 1938, the CCF committed itself to run candidates in the next provincial and elections setting up local riding clubs for that purpose.

[7][8] The Alberta wing of the Labour Party federated with the CCF in 1935, but ran its own candidates in the 1935 and 1940 provincial elections.

Irvine also advocated an alliance with the communist Labor-Progressive Party which would have been beneficial in the cities where the single transferable vote electoral system was used.

In Alberta, the NDP was founded in 1962 with a new leader, Neil Reimer, Canadian director of the Oil Workers International Union.

The decline of Social Credit and the unpopularity of the Liberals allowed the New Democrats to become the main opposition to the Lougheed-led Conservatives.

In the 1986 election, under Ray Martin's leadership, the party won 30% of the vote and 16 seats, marking a high point for New Democrat support.

Barrett resigned her position as party leader in 2000 after claiming a near-death experience in a dentist's chair.

Although McGowan was unable to speak on the issue before the resolution was defeated, he later addressed it during his report to the Convention as AFL President.

He urged members to acknowledge the need for significant change in light of 40 years of Tory government and the recent election results.

Both Rachel Notley and Brian Mason safely held onto their seats while David Eggen was re-elected as the member for Edmonton-Calder.

[17] On April 29, 2014, Brian Mason announced that he would step down as leader as soon as a leadership election could be held to choose his successor.

[19] The incumbent PC premier Jim Prentice called an election on April 7, 2015, following the reveal of a new budget to strengthen his party's mandate.

[21] The NDP had high expectations for Edmonton, given Notley's local ties and the city's historically favourable stance towards centre-left parties.

[22] At the time of the early election call Alberta was sinking into a deep recession caused by the collapse of world oil prices.

[23] As a result of the province's dependence on oil royalties over more traditional revenue sources, Alberta's deficit soared.

After reversing prior budget cuts, Notley mostly shied away from major wealth redistribution and preferred to stimulate the economy through infrastructure spending and maintaining public services.

[28][29] However, Notley moved forwards with a carbon pricing scheme and plans for sustainability and energy transitions early in her term.

[30] As a result plans to raise oil royalties were scrapped, and tax increases on corporations and higher income brackets were modest.

[31] Eventually this led to a schism between the NDP governments of Alberta and British Columbia over the twinning of the Transmountain Pipeline, which remained a contentious project in the Canadian political arena and particularly within the federal New Democratic Party.

[33] The NDP was dealt a severe blow when the PCs and Wildrose merged to form the United Conservative Party, which immediately ascended to a large lead in opinion polling.

[36] On January 16, 2024, Notley announced she would be resigning as party leader effective the next leadership election, scheduled for June 22, 2024.

[36] Former Calgary mayor Naheed Nenshi emerged victorious, winning with 86% of the vote, the largest for any winner of a provincial leadership election of any major political party in Canada.
