The 2015 Progressive Conservative Party of Ontario leadership election was held on May 9, 2015, as a result of the resignation of Ontario Progressive Conservative leader Tim Hudak following the provincial election on June 12, 2014, his second loss in a row as party leader. Patrick Brown won the leadership with 61.8% of votes allocated, defeating Christine Elliott who had 38.2%.
Rules and procedure.
The party's 76,587 members were eligible to cast votes by preferential ballot. The vote will be weighted so that each of the province's 107 ridings that has more than 100 votes cast are allocated 100 electoral votes; ridings in which fewer than 100 party members vote will not be weighted, but will instead have the votes counted as individual votes. If at least 100 members votes in each riding the number of electoral college votes needed to win will be 5,351. The registration fee was $75,000 plus a refundable deposit of $25,000 and the spending limit was $1.25 million. 20% of money raised by candidates after the first $100,000 will be transferred to the PC Ontario Fund. The lowest ranked candidate will be dropped from the next round as ballots are counted, and the first candidate to get 50 per cent of the votes will be declared the new leader.
