The 2020 Green Party of Canada leadership election took place between September 26 and October 3, 2020, to elect a leader to replace Elizabeth May, who resigned on November 4, 2019, after leading the party for more than a decade and achieving a record three seats in Parliament in the 2019 federal election. Eight candidates ran to replace her. While these candidates offered different visions for the future of the party and made various policy proposals, they all agreed that climate change is a serious issue, opposed the construction of new pipelines, supported a guaranteed livable income, and supported adopting some form of proportional representation in federal elections.

Annamie Paul is a Canadian activist, lawyer, and former politician who served as the leader of the Green Party of Canada from 2020 to 2021. She was the first Black Canadian and first Jewish woman to be elected leader of a federal party in Canada.
