Green Party of Canada leadership elections

The Green Party of Canada holds a national leadership election every 4 years, as stipulated under the party's current constitution.

Ballots are always mailed out in advance to all Green Party of Canada "members in good standing" - allowing the option of voting by mail to all party members who do not wish to attend the convention in person.

The party uses an instant-runoff voting (IRV) ballot system for the election of its leader and councillors and a standard yes-or-no ballot for voting on constitutional amendments.

Saanich—Gulf Islands MP and former Green Party leader Elizabeth May won the election, after campaigning as part of a joint ticket with Jonathan Pedneault; as co-leadership is not formally recognized in the party’s constitution, Pedneault will become Deputy Leader while the two seek to amend the party constitution.
