The College of Registered Psychotherapists of Ontario describes psychotherapy as delivered by a Registered Psychotherapist as follows: "In the course of engaging in the practice of psychotherapy, a member is authorized, subject to the terms, conditions and limitations imposed on their Certificate of Registration, to treat, by means of psychotherapy technique delivered through a therapeutic relationship, an individual’s serious disorder of thought, cognition, mood, emotional regulation, perception or memory that may seriously impair the individual’s judgement, insight, behaviour, communication or social functioning." See Psychotherapy Act, 2007, Section 4.
