The four leaders will gather tonight for their first debate, in what could become a turning point in the campaign.
Just about every leader will be on the ropes to prove themselves.
Philippe Couillard and Pauline Marois are in a bitterly battle for first place, while Francois Legault has nothing to lose. Tonight will also be one of Quebec Solidaire's Françoise David's rare chances to get major media attention.
But, while most of them will devote the entire day to preparation, the only newbie, Philippe Couillard is still campaigning this morning. He will spend an hour shaking hands at Central Station before holding a photo-op at 10 am, and then setting down to work.
"I'm going to be ready. I'm going to be in a good mood," says Couillard. "I'm just relaxing. I'm in very good shape. I love doing the campaign. I love campaigning."
The campaign has grown increasingly hostile as the Parti Quebecois has attacked Couillard for his past relationship with Arthur Porter, and the Liberal leader has said he has four or five questions stored up to use against Marois is she chooses to make the campaign personal.
A feud between Quebec Solidaire and the Parti Quebecois has also been building since the PQ announced Pierre Karl Peladeau as a candidate.
