Thibault is set to appear at the Quebec City courthouse this afternoon.
The 76-year-old pleaded guilty last year to submitting expenses for travel, gifts, meals and events for herself and her family during her 10-year appointment.
The Crown has argued she should go to prison for four years, for committing fraud while in a position of public trust and pay back $430,000.
For his part, Thibault's lawyer Marc Labelle has said his client has been "publicly crucified" and should serve a one-year sentence in the community.
Thibault recently told Radio-Canada she doesn't remember pleading guilty in 2014. She said she has been unfairly depicted in the media with "rumours and lies that help sell the news.
