The accused was charged with second degree murder after stabbing a stranger who was trying to help him.
The accused conceded he caused the death but raised the defence of not criminally responsible (NCR) on account of mental disorder under s. 16 of the Criminal Code.
The Crown argued the psychotic episode was solely substance-induced due to the accused's heavy drug use.
The court applied the holistic approach, considering the internal cause and continuing danger factors, and found the accused suffered from a pre-existing delusional disorder that was operative at the time of the offence.
The court concluded the accused lacked the capacity to know his act was morally wrong and rendered a verdict of not criminally responsible.
