Background
Thomas Harpula stabbed his father to death in 2017. He was charged with second-degree murder but found not criminally responsible on account of mental disorder. He is diagnosed with schizophrenia, cannabis use disorder, and gambling disorder. At the time of the offence, he had been experiencing psychotic symptoms and had consumed cannabis. Harpula was placed on a detention order and supervised by St. Joseph’s Healthcare Hamilton, eventually transitioning to community living.
At his annual review before the Ontario Review Board in 2025, after approximately one month in community placement, Harpula sought an absolute discharge, arguing he no longer posed a significant threat to public safety. His treating psychiatrist, Dr. Khashayar Shariati, testified that Harpula had complied with medication and had no breakthrough psychotic symptoms or positive drug screens in the past year. However, Dr. Shariati also testified that Harpula had poor insight into his mental illness and substance abuse risks, had discontinued volunteer work and substance abuse programming, and in 2023 had escaped placement while using cannabis and alcohol.
The Ontario Review Board denied the discharge request, finding that Harpula continued to pose a significant threat to public safety. Harpula appealed, initially arguing the Board’s conclusion was unreasonable, then shifting to argue the Board’s reasons were insufficient and that the Board had misapprehended evidence about his medication compliance and substance abstinence.
The Court’s Holding
The Court of Appeal for Ontario dismissed the appeal and upheld the detention order. While acknowledging that the Board’s reasons were brief and somewhat conclusory, the court found they were not unreasonable when read in their entirety. Under Part XX.1 of the Criminal Code, the Board must find that a person remains a “significant threat to the safety of the public”—meaning there is a real risk of physical or psychological harm that is serious in nature and supported by evidence.
The court identified several factors supporting the Board’s conclusion. First, the index offence was serious and had occurred less than ten years ago—Harpula had fatally stabbed his father multiple times while experiencing psychosis and after cannabis consumption. Second, despite recent medication compliance, Harpula demonstrated poor insight into his condition; he believed command hallucinations were the only warning sign he would monitor. Third, the court noted Harpula’s history of failed community placements, most notably in 2023, when he escaped, consumed cannabis and alcohol, and went to great lengths to avoid recapture by painting his vehicle and altering its license plate—conduct suggesting he would not voluntarily return if conditionally discharged. Finally, Harpula had been in community placement for only one month at the hearing, making it premature to assess sustained stability without intensive forensic support.
On the misapprehension argument, the court agreed that the Board had not explicitly relied on the specific quote Harpula challenged. However, the court found this did not affect the Board’s decision, which rested on documented evidence of Harpula’s lack of insight, his prior community conduct, and his recent return to community living.
Key Takeaways
- A person found not criminally responsible may remain detained if they continue to pose a significant threat to public safety, even when recent psychiatric history shows medication compliance and symptom stability.
- Poor insight into mental illness and substance abuse risks is a significant risk factor, particularly when combined with a serious prior violent offence and a history of community placement failures.
- Past efforts to escape supervision and avoid recapture can inform assessment of whether a person would comply with conditions of a conditional discharge.
- Detention orders remain appropriate when a person has only recently transitioned to community living and requires time to demonstrate sustained stability and treatment engagement.
Why It Matters
This decision clarifies appellate review of Ontario Review Board discharge decisions. While acknowledging that Board reasons sometimes lack analytical depth, the court confirmed that briefly stated conclusions can be upheld if they reflect reasonable judgment supported by evidence when read contextually. For appellants challenging Board decisions, the focus must be on demonstrating genuine unreasonableness in the Board’s assessment of threat, not merely demanding more elaborate explanation.
The decision reinforces that lack of insight into mental illness is a powerful risk indicator—often more significant than short-term symptom stability or medication compliance—particularly in cases involving serious violence. For not criminally responsible persons with serious index offences, recent good behavior in structured settings may not suffice for discharge if fundamental concerns about judgment and insight persist. The decision signals that Review Boards have considerable discretion in requiring lengthy periods of demonstrated stability before granting discharge, and appellate courts will defer to that discretion when grounded in evidence.
