Ontario's Liberal Party will be electing a new leader on Saturday, but the process starts now.

Delegates and ex-officio delegates will be filing in to Ryerson's Mattamy Athletic Centre at Maple Leaf Gardens in the morning, casting their first ballot as they register. When standard delegates were selected a couple of weeks ago, they declared their support for specific candidates and they are bound to that selection in the first round of voting. There are 1837 delegates expected to participate and over 400 ex-officios, which consist of former and current MPs and MPPs and Liberal party executives.

As it stands Sandra Pupatello leads the pack with 27 per cent of support, followed by Kathleen Wynne with 25 per cent. Then comes Gerard Kennedy (14 per cent), Harinder Takhar (13 per cent), Charles Sousa (10 per cent) and Eric Hoskins (five per cent). There are also a handful of independents who are free to vote for whomever they want to in the first round.

The candidate with the least amount of support on each ballot is forced to drop out of the race. They - and anyone else who can decide to bow out - then chooses to throw support behind someone else.

Voting will continue until a new premier is elected with 50 per cent plus one of the vote.
