The accused, previously found not criminally responsible for assault and uttering threats, was subject to a detention disposition.
The hospital sought a renewal of the detention order, arguing that the accused's cannabis use posed a significant threat to public safety.
The Ontario Review Board found that the accused had been consistently compliant with his antipsychotic medication and had not exhibited violent behaviour since the index offences, even when using cannabis.
The Board concluded that the evidence linking his cannabis use to a substantial risk of serious harm was speculative.
Finding that the accused no longer posed a significant threat to the safety of the public, the Board granted an absolute discharge.
