The premiership of Jason Kenney began on April 30, 2019 when Jason Kenney and his first cabinet were sworn in by Lieutenant Governor of Alberta, Lois Mitchell. Kenney was invited to form the 30th Alberta Legislature and became the 18th Premier of Alberta, following the 2019 Alberta general election where Kenney's United Conservative Party (UCP) won a majority of seats in the Alberta Legislature leading to the resignation of Premier Rachel Notley. By April 19, as the collapse in the price of oil worsened, Alberta's benchmark crude oil—Western Canadian Select—descended to negative pricing.
