Matthew Sweet-Grant was charged last week with aggravated assault and assault with a weapon after an 18-year-old man who fell asleep on the floor of the home was set on fire Dec. 8.
RCMP Const. Kris Clark has said previously that the victim had to receive treatment for second- and third-degree burns.
Eighteen-year-old Josh McWhirter has also been charged with aggravated assault after he allegedly videotaped the incident.
Sweet-Grant is expected to be sentenced in February after the completion of a pre-sentencing report that includes a psychiatric evaluation.
The victim's name has not been released by the police because of a request by the family. (CKIZ)
