Committee: Ontario Physicians and Surgeons Discipline Tribunal
Decision Date: 20 Dec 2022

On December 20, 2022, the Tribunal found that Dr. O’Brien failed to maintain the standard of practice of the profession in his care of patients and engaged in disgraceful, dishonourable or unprofessional conduct by:
  • failing to maintain boundaries with Patient A through the content/nature, tone, timing, and frequency/volume of text, email, and telephone communications with Patient A;
  • engaging in clinical encounters and communication with Patient A without remuneration;
  • altering Patient A’s chart at her request and without noting the alterations, despite maintaining in the record the original clinical notes which demarcated the changes;
  • failing to terminate his professional relationship with Patient A at an earlier date;
  • failing to seek earlier professional support and/or supervision with respect to his treatment of Patient A;
  • inappropriately accepting and engaging with Patient A’s work product containing confidential information of third parties, which was sent to his email; and
  • failing to expressly and directly instruct Patient A to stop sharing work product containing confidential information of third parties with him.
The Tribunal ordered that: 
  • Dr. O’Brien attend before the panel to be reprimanded;
