The Action Démocratique du Québec has been wiped out of the North Shore, a region of the province that swung heavily in their favour in 2007.
The ADQ lost all eight ridings that it won in the 2007 general election.
The ADQ fortress started to crumble with the defection of Champlain MNA Pierre Michel Auger to the Liberals in October.
Auger was in tough to retain the riding as he was up against former Parti Québécois MNA Noella Champagne, whom he defeated in 2007. Champagne has been declared elected, leading the Liberals by about eight per cent of the vote.
The ADQ was fighting on two fronts on the North Shore after stealing ridings from both the Liberals and the PQ in 2007.
In Trois-Rivières, Liberal candidate Danielle St-Amand won the riding with 40.1 per cent of the vote. The PQ's Yves St-Pierre placed a close second with less than 36 per cent, while the ADQ incumbent, Sébastien Proulx, ran third with less than 19 per cent of the vote.
Laviolette was the only riding on the North Shore to elect a Liberal in 2007, sending Transportation Minister Julie Boulet to Quebec City. Boulet was easily re-elected with 58 per cent of the vote.
The Liberals were eyeing three ridings that they lost to the ADQ in 2007, Trois-Rivières, Maskinongé and Portneuf.
Liberal Jean-Paul Diamond was elected in Maskinongé.
In Portneuf, ADQ incumbent Raymond Francoeur was trying to cling to the riding he won in 2007. Liberal Michel Matte won the riding with a six per cent margin of victory over the ADQ.
In Berthier, the ADQ's François Benjamin lost to the PQ's André Villeneuve, who won with more than 42 per cent of the vote. The riding has see-sawed between the PQ and the ADQ in recent elections. The ADQ took the riding in a 2002 byelection and lost it to the PQ in the 2003 general election before winning it back in 2007.
In Joliette, ADQ incumbent Pascal Beaupré lost to PQ candidate Véronique Hivon, who carried the riding with around 46 per cent of the vote.
The PQ also held Prévost until 2007, when the ADQ's Martin Camirand won. However, PQ candidate Gilles Robert won the riding with about 44 per cent of the vote.
Former PQ MNA Claude Pinard won back the Saint-Maurice riding that he lost in 2007 to Robert Deschamps of the ADQ. Saint-Maurice was the closest riding in the region with Pinard winning by three per cent of the vote.
The PQ held two ridings heading into the election, with Claude Cousineau in Bertrand and François Legault in Rousseau.
