Dellen Millard will be back in court today.
Millard will appear in a Toronto court for a pre trial hearing in his third murder trial.
The convicted killer is set to stand trial in March in the death of his father.
Wayne Millard's death in 2012 was initially ruled a suicide but police charged his son Dellen with murder in 2014.
Millard has already been found guilty in the murders of Tim Bosma and Laura Babcock.
A judge will decide in the coming weeks if Millard will serve those life sentences at one time, or one after another.
