Communicating a Diagnosis


Under the Naturopathy Act, 2007, a naturopath is authorized the controlled act of “communicating a naturopathic diagnosis identifying, as the cause of an individual’s symptoms, a disease, disorder or dysfunction that may be identified through an assessment that uses naturopathic techniques.”

That naturopathic diagnosis can be identified through one or more of:
  • A patient’s health history.
  • The findings of an objective patient evaluation, including a physical examination.
  • The results of any relevant tests or investigations.

When communicating a diagnosis, the general requirements for performing a controlled act, outlined on the About Controlled Acts page, do not apply.  Instead, a naturopath must ensure that:
  • There is a naturopath-patient relationship with the patient.
  • The naturopath has the knowledge, skill and judgment to perform the controlled act safely, accurately and ethically.

What is a Naturopathic Diagnosis?


Ontario statutes do not define “diagnosis” or “naturopathic diagnosis”.  

The College of Naturopaths of Ontario has interpreted “naturopathic diagnosis” to mean a diagnosis determined by a naturopath, and would apply the generally accepted definition used by health professions, i.e. the use of a differential diagnosis.

Prohibition on Delegation


The Delegation Regulation prohibits a naturopath from delegating to another individual the controlled act of communicating a naturopathic diagnosis.  This is based on the premise that a naturopathic diagnosis is a diagnosis that is communicated by a naturopath.  If delegation were permitted, then a naturopath would no longer be communicating that diagnosis.
