How to Become a Medical Radiation Technologist in Ontario
Medical radiation and imaging technologists in Ontario register with CMRITO in one of five specialties: an approved program, the CAMRT or Sonography Canada exam, and a jurisprudence course.
How to Become a Radiation Therapist in Ontario
How to become a radiation therapist in Ontario: CMRITO registration, the CAMRT certification exam, approved programs, and fees.
Applies in: Ontario
The short answer
To become a radiation therapist in Ontario, complete a CMRITO-approved medical radiation sciences program in the radiation therapy specialty, apply to the College of Medical Radiation and Imaging Technologists of Ontario (CMRITO), complete CMRITO's jurisprudence course, and pass the Canadian Association of Medical Radiation Technologists (CAMRT) certification exam in radiation therapy. You must be registered with CMRITO to practise in Ontario — the title "medical radiation and imaging technologist" and the specialty title MRT(T) are protected. Expect $141.25 for the CMRITO application, $694.95 a year for registration, and $980 per CAMRT exam attempt, all before any program tuition.
Step 1: Complete a CMRITO-approved radiation therapy program
CMRITO requires successful completion of a medical radiation and imaging technology program in the specialty that was approved by the CMRITO Council at the time you completed it. The approved-programs list names the Ontario institutions currently providing approved programs. For radiation therapy, the routes are:
- The Michener Institute of Education at University Health Network with the University of Toronto — a joint Bachelor of Science degree and Advanced Diploma in Medical Radiation Sciences, with radiation therapy as one of three disciplines. The program is designed for students with prior university experience and offers an intensive 32-month curriculum. The Michener Institute also offers a joint radiation therapy program with Laurentian University, based in Toronto and Sudbury.
- McMaster University and Mohawk College — a collaborative program leading to an Honours Medical Radiation Sciences degree from McMaster and an Ontario College Advanced Diploma from Mohawk. Students choose a specialization from Level II, including radiation therapy, and graduates of the radiation therapy specialization are eligible to sit the CAMRT certification exam.
Check that the program and stream you enrol in is on CMRITO's approved list for radiation therapy specifically — the same schools run other specialties (radiography, nuclear medicine, sonography) that lead to different registrations. If you are comparing programs, confirm the intake requirements, clinical placement locations, and tuition on each program's own page before you apply.
Step 2: Apply to CMRITO
Apply for a certificate of registration through the CMRITO Portal. CMRITO's registration requirements apply to every applicant:
- Language fluency — demonstrate verbal and written fluency in English or French, through proof that your program was conducted in English or French or by completing an approved language fluency test.
- Citizenship or work authorization — be a Canadian citizen, a permanent resident of Canada, or authorized under the Immigration and Refugee Protection Act (Canada) to engage in the practice of the profession.
- Jurisprudence course — successfully complete a course in jurisprudence set or approved by CMRITO.
- Conduct disclosures — provide details of any finding of guilt for a criminal offence, current investigations or proceedings involving professional misconduct, incompetence or incapacity, findings of professional misconduct or negligence, and show that your past and present conduct gives reasonable grounds to believe you will practise with decency, honesty and integrity.
- Fees — pay the application fee and, if applicable, the evaluation fee.
On top of those, the essential requirements are: successful completion of an approved program in the specialty; clinical practice in the specialty, or successful completion of the program, within the five years immediately before the application; and payment of the applicable fees. If you completed your program more than five years ago and have not practised in the specialty since, you do not meet the currency requirement — check with CMRITO what refresher or re-entry route applies before you apply.
The application and registration fees are $141.25 including HST for each specialty, plus a $282.50 evaluation fee including HST if your application requires an evaluation of your educational program by the Registration Committee. CMRITO fees and penalties are non-refundable. You must apply separately, and pay the application and evaluation fee, for each specialty you seek registration in.
Step 3: Pass the CAMRT certification exam
Passing the examination approved by the CMRITO Council is a non-exemptible requirement — there is no way around it. For radiation therapy, that is the certifying examination of the Canadian Association of Medical Radiation Technologists. The CAMRT exam dates and fees page sets out the sittings: exams are held in January, May, and September each year, with radiation therapy exams on Day 2, typically a Tuesday. The 2027 sittings are January 11–12, May 10–11, and September 13–14, 2027.
The certification exam fee is $980 per attempt, plus a remote proctoring fee of $88.63 plus applicable taxes or a test centre fee of $171.75 plus applicable taxes. All fees are in Canadian dollars. Registration periods and accommodation submission deadlines are published with each sitting — for the January 2027 sitting, registration ran September 28 to November 6, 2026 — and CAMRT states plainly that all registration deadlines are final, with no exceptions permitted. Register early, and check your email (including junk folders) for the confirmation that lets you reserve your exam seat.
Step 4: Register and keep your registration current
Once you have met every requirement, including the exam, you pay the annual registration fee and receive your certificate of registration. The annual registration fee is $694.95 including HST ($615.00 plus $79.95 HST), the same for all registrants regardless of hours worked or number of specialties. Registration fees for new registrants are prorated in the first year based on your registration date and your birthday — CMRITO provides a fee calculator for the exact first-year amount.
Your renewal date is your birthday, every year. Notices are emailed 30 to 60 days before your birthday, and you renew online through the CMRITO Portal, completing the annual declaration questions and updating your registrant information. If you do not pay within 14 days after your birthday, a late penalty of $173.74 applies. If you do not renew and pay within three months after your birthday, your certificate of registration is suspended for failure to pay fees and you are no longer legally authorized to work as a medical radiation and imaging technologist in Ontario. If you are not working in Ontario or are on a temporary leave, you may resign from CMRITO and reinstate before you return to work — reinstatement after suspension costs no less than $1,042.43 and no more than $1,389.90, depending on your circumstances.
The internationally trained route
If you trained as a radiation therapist outside Canada and want to practise in Ontario, you are assessed by CMRITO itself. CAMRT's own guidance is explicit: internationally educated medical radiation technologists who wish to practise in Ontario, Alberta, or Quebec must be assessed by the regulatory authority in that province. CMRITO's career map for internationally trained applicants sets out the steps: an online application, assessment of academic credentials, a clinical competence assessment, the jurisprudence course, language proficiency, and the CAMRT examination, followed by evidence of recent practice and payment of the registration fee.
Two things to check before you start. First, the currency rule applies to you too — you need clinical practice in the specialty, or program completion, within the five years immediately before your application. Second, CAMRT temporarily paused acceptance of new internationally educated credential assessment applications effective October 12, 2026, while it moves to a new Credential Assessment Portal anticipated to launch by early November 2026; existing applications continue to be processed, and prospective applicants are told to use the pause to gather and organize their documentation. That pause affects CAMRT's own assessment stream — since Ontario-bound applicants are assessed by CMRITO, confirm with CMRITO which parts of your application, if any, depend on the CAMRT portal before you wait on it.
Finding work once you are registered
Radiation therapists work in hospital cancer centres and regional cancer programs across Ontario, delivering radiation treatment to patients with cancer and other conditions. Every employer in Ontario requires CMRITO registration, so finish the registration steps first and use the job search to target the region and centre you want. The Michener and McMaster programs both include clinical placements in Ontario facilities, which is where most graduates make their first employer contacts.

The CMRITO fees in this guide ($141.25 application, $282.50 evaluation, $694.95 annual registration, $173.74 late penalty, and the $1,042.43 to $1,389.90 reinstatement range) were verified on CMRITO's own fee page. The CAMRT exam fee of $980 per attempt, the $88.63 remote proctoring fee, the $171.75 test centre fee, and the 2027 sitting dates were verified on CAMRT's own exam dates and fees page. The five-year currency rule, the jurisprudence requirement, and the citizenship and language requirements were verified on CMRITO's registration requirements page. The following figures were cut because they could not be verified on an opened official page: radiation therapist wages in Ontario (no current verified figure — check Job Bank and hospital postings for the region and role you want); program tuition (check the Michener, University of Toronto, Laurentian, McMaster, and Mohawk program pages directly); the length of the Michener–Laurentian joint program (the 32-month figure in this guide is for the Michener–University of Toronto program only); and the CAMRT exam question count and pass mark (not stated on the CAMRT pages opened — check CAMRT's candidate information before you write).
