The vote has begun to determine who will lead the Liberals and become the party's next hope for regaining power.
The first round began at 11:30, and will run until 1:30. The first round's results should be unveiled at 2 pm.
Before voting began, each candidate made their final pitch to the crowd. Pierre Moreau gave an energetic and passionately delivered speech about opposing the PQ and keeping Quebec and Canada united.
"Pauline Marois' government as you all know, is highly incompetent," said Moreau.
The premier has one purpose: to promise anything to gain a majority and "plunge Quebec into another period of great divide," he said. "We don't want another referendum."
Philippe Couillard also spoke of uniting Quebecers. He promised to review the Quebec tax system and restore the party's reputation and integrity.
Raymond Bachand spoke for several minutes, directly to Quebec's English speakers. He told them he would defend their institutions and work to keep another generation of Anglophones from leaving Quebec.
"I do not and I will not take you for granted," he said. "I will make sure that you support us, not because you have no other option, but because you truly believe that we are the best option for you."
If the front-runner, Philippe Couillard, fails to gain more than 50 % of the votes in the first round, the candidate with the smallest number will be dropped from the ballot, and Couillard will go one-on-one against whoever's left: either Pierre Moreau or Raymond Bachand.
Both Moreau and Bachand are hoping to pick up the other's supporters - a scenario that could potentially bring about a surprise win.
If the Liberal vote heads to a second round, the Liberals will have a leader at 5:30 tonight.
