The Green Party of Canada held a co-leadership ratification election on February 4, 2025.
On November 19, 2022, Elizabeth May was elected leader of the party once again, promising to convert the current leadership model into a co-leadership model, with Jonathan Pedneault being her co-leader. Notably, four of the six candidates approved to run in the 2022 leadership race campaigned as part of joint tickets, promising to appoint the losing member of their ticket as a deputy or co-leader. As co-leadership was not recognized in the Green PartyâÂÂs constitution at the time of the leadership election, a move to shared leadership required approval from the Green Party. Former party leader Elizabeth May campaigned with Jonathan Pedneault; he became Deputy Leader while the two sought to amend the party constitution.
In February 2024, party members were to vote on motions which, if passed, would have amended the party's constitution to implement a co-leadership model. However, Pedneault was unsuccessful in his attempt to win a seat in the House of Commons through a by-election and the proposed constitutional amendment was not voted upon due to disagreement within the party. On July 9, 2024, Jonathan Pedneault resigned as deputy leader, citing personal reasons. He returned in January 2025 to serve as co-leader, pending election by party membership, which was approved on February 4, 2025, in a landslide. However, while the vote was approved by 89.4% of the 2,990 Green Party of Canada members who voted, 71% of the total 10,301 Green Party of Canada members who were eligible to cast a ballot did not vote.
