Quebec Superior Court Justice Marc David has set aside three months for Guy Turcotte's jury trial.
Turcotte was not in court in St-Jerome on Friday as David set Sept. 14, 2015, as the start date.
In 2011, a jury found Turcotte not criminally responsible in the stabbing deaths of his children Anne-Sophie and Olivier in 2009.
The Crown successfully appealed the verdict last November and Turcotte was re-arrested.
In March, the Supreme Court of Canada announced it wouldn't hear his appeal of that decision.
The former cardiologist remains incarcerated at Montreal's Pinel Institute, a mental-health facility.
