Bourque previously pleaded guilty to shooting five RCMP officers on June 4, when he wandered through a north end neighbourhood of the city, dressed in camouflage and carrying a high-powered weapon.
Court is set to resume at 9:30 a.m. AT
A 30-day psychiatric assessment report that was previously under a publication ban is expected to be released.
Physical evidence is also expected to be presented.
On Monday, the packed courtroom heard 10 emotional victim impact statements, 911 calls from the night of the shootings and the approximately 3½-hour video statement Bourque gave to police shortly after his arrest on June 6.
During the statement, Bourque rambles about everything from evolution to socialism to events overseas.
He also brags about his "good moral compass," his tactical skills and how he felt "accomplished" following the shootings.
At the end of the video, however, Bourque asked if the officers who were killed were married and was told they all had children.
He later wrote a note to the families of Const. Doug Larche, Const. Dave Ross and Const. Fabrice Gevaudan, saying he wasn't asking for forgiveness, but that he apologizes.
Bourque stared straight ahead throughout most of the proceedings, showing no emotion.
Others in the packed courtroom, including some of the relatives of the victims and other RCMP officers, shook their heads and wiped away tears.
The Crown is seeking three consecutive life terms, which would leave Bourque not eligible for parole for 75 years. That would be the longest prison sentence in Canadian history.
Although defence counsel David Lutz has yet to present his arguments on sentencing, Crown prosecutor Cameron Gunn indicated in his opening remarks Monday that the defence would be seeking a reduction of 25 to 50 years in exchange for Bourque pleading guilty.
Up until 2011, the maximum sentence a multiple killer could be given in Canada was life in prison with no parole eligibility for 25 years.Suggest a correction
