A second day of voting is set for Thursday in the campaign to be the new leader of the Ontario PC Party.
Voting started on Sunday, with more than 76,000 PC members able to cast ballots.
The winner will be announced at a event in Toronto on Saturday.
The race is between Whitby MPP Christine Elliott and Barrie MP Patrick Brown.
PC members are voting in each of the province’s 107 ridings, but the results will be weighted to give each riding 100 points — so neither candidate can win by stacking all their support in only a handful of heavily-populated ridings.
The party is looking to reinvigorate itself after a defeat in last year’s provincial election.
