A jury found that Richard Kachkar, 46, was mentally disturbed and couldn't appreciate what he was doing when he killed Sgt. Ryan Russell, 35, two years ago.
A hearing before the Ontario Review Board, which manages people found not criminally responsible in the province, has been scheduled for April 26 and will take place in a Toronto courtroom.
The board will determine whether Kachkar will be sent to a mental hospital or released into the community.
If he is sent to a hospital the board will review Kachkar's case annually and only when they decide he is no longer a significant threat to the safety of the public will they release him.
Under changes proposed by the Conservative government, people found not criminally responsible and designated a high-risk offender could have their time between hearings lengthened to three years.
