That beats the previous record set by the Conservatives in 2017, when 259,010 members could cast a ballot. When Jagmeet Singh won the NDP leadership in 2017, about 124,000 members were eligible to vote. With the exception of Alberta, those are provinces that traditionally have had fewer Conservative members. The Conservative Party won 47 of 48 ridings in these two provinces in the October federal election. Turnout in the 2017 leadership race was about 54 per cent, with 141,000 of the 259,000 eligible members casting a ballot.
