UPAC is still investigating the Liberal party of Quebec.
This week the province's permanent anti-corruption task force questioned Marie-Eve Ringuette, the party's general manager.
Last week Surete du Quebec officers met party leader Philippe Couillard at his home, just days after Couillard confirmed that in July the party's offices had been subject to a search by police.
Ringuette was in charge of Liberal party finances from 2009 until 2013, when she took over as general manager following the departure of Karl Blackburn.
The Liberal party said that Ringuette was questioned about the inner workings of the party.
Couillard said that police seemed to be interested in events that happened several years ago, before political contributions were capped at $100 per individual, and before the 2011 law against false fronts came into effect.
