NDP Leadership: 2017 Voting and Rules

Voters will use a ranked-choice ballot and list the candidates in their preferred order – at least one candidate must be selected.

Mail-in or Internet voting is available. Those using the latter option can change their ballot preferences between each round -- or leave their vote as is.

Watch our explainer for more:

Round 1 is scheduled for Sept. 18 to Oct. 1, with the results announced Oct. 1 at Toronto's Westin Harbour Castle. If no candidate wins a majority, the last-place candidate is dropped for subsequent rounds until a winner emerges.

Round Two: Oct. 2 to Oct. 8 (announcement in Montreal)

Round Three: Oct. 9 to Oct. 15 (announcement in Ottawa) More rules:

• The official campaign period begins July 2 and ends with the announcement of a winner by Oct. 29. Candidates must be registered by July 3.

• Any party member eligible to run for the House of Commons and “who demonstrates a genuine interest in seeking the leadership can run.”

• There is a $30,000 non-refundable registration fee.

• Prospective candidates must have the support of 500 party members to register, with a minimum of 50 each from Quebec, Ontario, and the Atlantic, Prairies, and B.C./North regions. At least half must be from “female-identified members,” and at least 100 must be from “other equity-seeking groups” such as Visible Minorities and Aboriginals.

• Candidates can spend up to $1.5 million on official expenses.

• At least two official debates are planned – one each in English and French. Another bilingual debate on youth issues is also expected.

• Voters must be NDP members in good standing by Aug. 17.

• A “Candidates Showcase” is planned on Sept. 17, one day before the voting period begins.

• Events are planned to announce each round’s result. Candidates will have the opportunity to speak each time.

• Current MPs who run will be relieved of their regular “House duty” on Parliament Hill, and removed from committees and critic roles. While speaking in the House of Commons, they must not criticize other candidates or party policies. Oral questions to ministers must be on local issues.
