With re-drawn boundaries, it is difficult to predict which way Ahuntsic-Cartierville will lean on election night, making it one of the key ridings to watch.

Both the Bloc Quebecois and Liberals have won in the riding in the past, while the incumbent is a former Bloc Quebecois MP now running for the NDP.

While some voters in the riding may be reticent to vote NDP, others are willing to give the party a try with seasoned MP Maria Mourani.

“Sometimes they say, ‘Don't worry, we're going to vote for you, you are our Member of Parliament for nine years. We know you. You work a lot,’” she said.

Mourani is facing stiff competition from star Liberal candidate Melanie Joly, who said voters in this riding are craving something fresh.

“Francophone voters and, in general, progressive voters are just looking to get rid of the Harper government and clearly, the only choice is the Liberal party because of our support throughout the country,” she said.

Still, Bloc Quebecois candidate Nicolas Bourdon is convinced long-time Bloquistes will remain loyal.

“I have these people with me, helping me, supporting me, so this is great,” he said.

Bourdon is not convinced people will stay loyal to Mourani, who had a falling out with the Bloc over the party's support of the PQ's proposed Charter of Values.

“Some people are angry because she was a sovereignist and she just jumped to federalist and it was really quick and people didn't understand,” he said.

Each candidate has different priorities for the multi-ethnic riding.

Mourani is focused on fighting poverty.

“We have big families -- families with five, six children. So affordable housing is important,” said Mourani.

Joly wants to revitalize the local economy.

“Chabanel over the past nine years has been suffering from the fact that there's been no investment on the part of the federal government, and there's huge potential,” she said.

Bourdon wants to block the Energy East pipeline.

“For the environment, it would be a disaster,” he said.

The race to win this re-drawn riding won't be easy, and all the candidates say they're not taking anything for granted.
