Beatrice Zako, the NDP hopeful in the Montreal riding of Papineau, used to be in Option nationale, a pro-independence provincial party in Quebec.
But Zako likened her flirtation with independence to a brief love affair. In this case, it was a three-month fling, the length of time she was a member of the party's national council.
"Sometimes you get charmed, you believe in something," Zako told The Canadian Press.
"But it only lasted three months. Three months is not really a long time. It took me three months to realize that was not where I really wanted to defend the interests of society."
Option nationale confirmed Zako resigned shortly after party founder Jean-Martin Aussant stepped down in 2013.
Zako's fling with sovereignty might have been brief but was reportedly quite passionate.
In a 2013 blog for French-language magazine L'actualite, veteran political commentator Josee Legault quoted part of a speech Zako gave at Option nationale's convention that reportedly thrilled the crowd.
"I am a Quebecer and proud of it," she was quoted as saying. "I have had two children in Quebec. Quebec is their homeland, their country and my country. I want to give my children a country. I am looking forward to exchanging my Canadian passport for a Quebec one."
Moreover, in a document submitted to the 2013 convention, Zako wrote: "I have followed Quebec politics, analyzed situations and it is time for me to choose. So I have decided to fight for QUEBEC INDEPENDENCE.''
The NDP said it isn't bothered by Zako's former political affiliation.
Party spokesman Marc-Andre Viau said Zako's community service exposed her to different political parties at the provincial and municipal level.
"She was interested in the political adventure ... and quickly realized that the sovereigntist option was not for her," he said in an email.
Asked whether Quebec's future should be as a province or a country, Zako replied: ''That's a very, very good question. But nowadays I am a federalist. I'm working with the NDP.''
Zako will be up against Liberal Leader Justin Trudeau, who has held Papineau since 2008.
