REASONS FOR DISPOSITION
(Dated March 6, 2025)
Introduction
On May 8, 2018, John Wren appeared in court on charges of uttering threat, failure to attend court and failure to comply with recognizance, offences contrary to the Criminal Code of Canada.
The trial court received psychiatric evidence establishing that Mr. Wren was suffering from a serious mental disorder when he committed the index offences. Based on that evidence, the court ruled that he was not criminally responsible on account of mental disorder (NCR).
Mr. Wren is currently subject to a disposition of the Ontario Review Board (ORB or “the Board”) dated December 6, 2023, discharging him on certain conditions.
On January 13, 2025, the Board convened at the Royal Ottawa Mental Health Centre (ROMHC or “the hospital”) to conduct an annual review. Mr. Wren appeared in person. He was represented by counsel, Ms. Marni Munsterman.
The Board received direct testimony from the attending psychiatrist, along with documentary evidence, including a hospital report, dated November 15, 2024.
The issues to be considered by the Board are whether Mr. Wren still presents a significant risk to the safety of the public, and if so, to determine the necessary and appropriate disposition.

Counsel for Mr. Wren supported the hospital recommendation that Mr. Wren no longer presents a significant threat to the safety of the public and that he should be discharged with no conditions. Upon the completion of evidence, counsel appearing for the Attorney-General, Ms. Dufort, also agreed.
For the reasons set out below, the Board determined that Mr. Wren no longer presents a significant threat to public safety. He was granted an absolute discharge.
