Dellen Millard has been found guilty of first degree murder in the death of his father.
This is the third time Millard has been convicted of murder - he is already serving time for the deaths of Tim Bosma of Ancaster and Laura Babcock of Toronto.
Wayne Millard died in 2012.
During the judge only trial, the crown accused Millard of killing his father because Dellen felt he was squandering millions in potential inheritance money on a new aviation business.
