Guy Turcotte made his first court appearance Tuesday since he was granted bail last year.
The former cardiologist is awaiting a second trial for the killing of his two children, five-year-old Olivier and three-year-old Anne-Sophie, in 2009.
In 2011 a jury found Turcotte not criminally responsible for the deaths, but in 2013 Quebec's Court of Appeal overturned that verdict and ordered a new trial, which is scheduled to begin in September 2015.
Isabelle Gaston, the mother of the children and Turcotte's ex-wife, was among those angered when Turcotte was granted bail.
In court this week the Crown and defence lawyers are laying out their plans and debating which witnesses will be called for the new trial.
The exact details of the pre-trial motions presented Tuesday are subject to a publication ban and may not be revealed.
Pre-trial hearings are meant to settle legal issues, so the actual trial doesn't get interrupted, explained Crown prosecutor Rene Verret.
Onlookers say Turcotte seems physically weak, and was walking slowly in the court hallways.
When physical evidence, including photographs, was presented in court Tuesday morning Turcotte looked at the ground, refusing to look at the images.
After his first trial Turcotte was ordered into psychiatric treatment, and he continues to see doctors.
Turcotte's second trial begins on Sept. 14.
