Pauline Marois and Philippe Couillard campaign in Laval

Both PartiQuébécois leader Pauline Marois and Liberal Leader Philippe Couillard spent the day campaigning in Laval.

The city has six ridings — four seats were held by the Liberals and two by the PQ at the dissolution of the national assembly.

Marois says this time around, the PQ could win all seats excepts for the Liberal stronghold of Chomedey.

The party's running union activist Jean Poirier in Vimont and outspoken secular-charter supporter DjemilaBenhabib in Mille-Îles.

A star candidate in the last election, Léo Bureau-Blouin is running again in the riding of Laval-des-Rapides.

“I know that could be difficult ... but [it] is possible and imaginable for the majority of the seats,” said Marois, adding that the PQ government invested more than $100 million dollars in Laval.

Laval Mayor Marc Demers ran twice for the PQ, but he says he is not playing favourites in this election.

“I have my personal opinion ... and that I will keep as an individual,” Demers said.

Liberal Leader Philippe Couillard says he wants to consolidate support by focusing on the economy, and he told Laval residents Monday that a vote for the PQ is a vote for a referendum.

“We are offering the people of Laval to be represented by people who will focus only on the economy, jobs, health care and education — not false issues or false problems.”

Laval residents say there could be some tight races in some of the city’s six ridings— although some are not convinced the PQ could pull off a sweep.

“I think it’s a little bit ambitious, but surely it’s an open ground,” said Joe Ghafari.

“I don’t think she’ll get a sweep,” said Joe Sferlazza.
