Jacques Duchesneau quits politics

Jacques Duchesneau, one of the best-known members of the Coalition AvenirQuébec (CAQ), has announced he will not run in the next election.

Duchesneau says being a politician is not what he thought it would be, and he’s had enough of politics.

“It's so disappointing. You can't imagine how frustrating it is for me,” Duchesneau said during his surprise announcement on Thursday.

Duchesneau said he thought politicians of different parties could work together, and that the opposition would get straight answers during question period.

“I can’t stand it when politicians stand up and lie to us,” he said, adding that the overly partisan atmosphere in the national assembly makes him feel physically ill.

Tough stance on corruption

Jacques Duchesneau was an anti-corruption czar when he announced he would run for the CAQ in 2012 in the riding of Saint-Jérôme.

The former chief of the Montreal police service, who is known for not mincing words, wrote a report for Quebec’s transport minister, suggesting corruption was widespread and entrenched.

The report paved the way for the creation of the Charbonneau Commission.

Duchesneau says the decision to leave politics was a difficult one.

“"That's probably why it was so emotional when I spoke with my colleagues — I felt like I am betraying the team.  It's simply [that] I cannot take it anymore."

Duchesneau says still believes in CAQ policies and will continue to advise party leader François Legault.
