Regulation changes enable NPs to order CTs and MRIs as of July

As of Friday, July 1, 2022, Nurse Practitioners (NPs) will be able to order computerized tomography (CT) and magnetic resonance imaging (MRI) scans.

These changes mean that NPs can provide more direct care to support patient safety, and better connect patients with needed tests in a timely manner.

Here’s how the CT and MRI scan changes will be implemented, what they mean for NP practice and how they can help support safe patient care.

Here’s how the CT and MRI scan changes will be implemented, what they mean for NP practice and how they can help support safe patient care.

Supporting safe patient care

When it comes to CTs and MRIs, NPs currently work collaboratively with other care professionals to ensure patients can access the tests they need. When NPs are able to directly order the scans in July, they’ll be able to save a step in this process, which will enable them to provide more direct care to patients.

Understanding the changes

To enable these changes, the government amended regulations under two pieces of legislation: the Healing Arts Radiation Protection Act, 1990 (HARPA) and the Regulated Health Professions Act, 1991 (RHPA).

Previously under HARPA and the RHPA, NPs were not authorized to order CTs and MRIs. When the regulatory changes take effect on Friday, July 1, 2022, NPs’ practice will include the authority to order CTs and MRIs. Ordering tests that involve nuclear medicine will remain prohibited for NPs.

Ensuring safe practice

Nurse Practitioners are expected to have the knowledge, skill and judgment to order appropriate tests. When ordering tests like CTs and MRIs, NPs are accountable to existing practice standards, including Decisions about Procedures and Authority and Nurse Practitioner.

Depending on their individual learning needs, NPs also can review ordering CT and MRI scans as part of their annual learning plan and ongoing learning for this year’s Quality Assurance (QA) Program.

About CNO

The College of Nurses of Ontario (CNO) is the regulator of the nursing profession in Ontario. It is not a school or a nursing association. CNO acts in the public interest by:

  • assessing qualifications and registering individuals who want to practice nursing in Ontario.
  • setting the practice standards of the profession that nurses in Ontario are expected to meet.
  • promoting nurses' continuing competence through a quality assurance program.
  • holding nurses accountable to those standards by addressing complaints or reports about nursing care.

The College was founded in 1963. By establishing the College, the Ontario government was acknowledging that the nursing profession had the ability to govern itself and put the public's well-being ahead of professional interests.

For the latest information, please see our Nursing Statistics page.

Anyone who wants to use a nursing-related title — Registered Nurse (RN), Registered Practical Nurse (RPN) or Nurse Practitioner (NP) must become a member of CNO.

Frequently Asked Questions

Go to the public Register, Find a Nurse, to conduct a search for the nurse. Contact us if you can't find the person you are looking for.

All public information available about nurses is posted in the public Register, Find a Nurse, which contains profiles of every nurse in Ontario. Publicly available information about nurses include their registration history, business address, and information related to pending disciplinary hearings or past findings.

Unregistered practitioners are people who are seeking employment in nursing or holding themselves out as being able to practice nursing in Ontario, but who are not qualified to do so. They are not registered members of CNO. Only people registered with CNO can use nursing-related titles or perform certain procedures that could cause harm if carried out by a non-registered health professional. CNO takes the issue of unregistered practitioners seriously. See Unregistered Practitioners for more information.

To ensure procedural fairness for both the patient (or client) and the nurse, the Regulated Health Professions Act requires that information gathered during an investigation remain confidential until the matter is referred to the Discipline Committee or Fitness to Practise Committee. CNO will not disclose any information that could identify patients (or clients) or compromise an investigation. See Investigations: A Process Guide for more information.

Information obtained during an investigation will become public if the matter is referred to a disciplinary hearing. If a complaint is not referred to a hearing, no information will be available publicly.

See CNO's hearings schedule, which is updated as hearing dates are confirmed. Hearings at CNO are open to the public and the media. For details on how to attend a hearing, contact the Hearings Administration Team.

A summary of allegations and the disciplinary panel outcomes can be found on the public Register, Find a Nurse. Full decisions and reasons are also available.

Where a disciplinary panel makes a finding of professional misconduct, they have the authority to reprimand a nurse, and suspend or revoke a nurse's registration. Terms, conditions and limitations can also be imposed on a nurse's registration, which restricts their practice for a set period. Nurses can also be required to complete remedial activities, such as reviewing CNO documents and meeting with an expert, before returning to practice.
