Quebec Justice Minister Stephanie Vallee will not run again in this year's provincial election.
Vallee held a news conference in Quebec City on Wednesday to say she wants to focus on her family and on her private life.
"I want to reclaim my family life and my personal life, it's as simple as that," she said.
Vallee added that she expects to remain involved in politics in some capacity.
She has been on the hot seat in recent years, dealing with the management of the Quebec justice system following a Supreme Court ruling on delays in cases getting to trial.
Vallee was also tasked with the difficult job of adopting the legislation on face coverings.
She has represented the riding of Gatineau since 2007.
Five other Liberal members have declared they won't run again while a handful of others are mulling their future.
The Liberals currently hold 69 of the 125 seats in the legislature.
