Ryan Grantham, a former child actor, was found guilty of killing his mother and received a life sentence.
Grantham, who is well-known for his work in Riverdale and Diary of a Wimpy Kid, pleaded guilty to the second-degree murder of his mother.
On September 21, the 24-year-old received a life sentence without the chance of parole for 14 years.
Grantham shot his mother on March 31, 2020, when she was practicing the piano in their townhouse in Squamish, North Vancouver.
Ryan allegedly planned to murder Justin Trudeau after killing his mother, according to testimony given in court.
In British Columbia, a second-degree murder conviction carries a sentence of 10 to 25 years without the possibility of release.
Grantham tried to make Molotov cocktails, used marijuana, and drank beer after the murder.
