Becoming a Registered Nurse in Ontario if You Trained Abroad: The Real Process

Only nurses registered with the College of Nurses of Ontario can legally use the title 'nurse' or 'Registered Nurse'. If you trained outside Canada, your first step isn't applying to CNO directly, it's a credential assessment through NNAS, followed by the NCLEX-RN exam, a jurisprudence exam, and Ontario's Evidence of Practice and Transition to Practice requirements.

Only nurses registered with the College of Nurses of Ontario (CNO) can legally use the title “nurse” or “Registered Nurse” in Ontario. If you trained as a nurse outside Canada, your first step isn’t applying to CNO directly; it’s a credential assessment through the National Nursing Assessment Service (NNAS). From there, you’ll need to pass the NCLEX-RN exam and a jurisprudence exam, and meet Ontario’s Evidence of Practice and Transition to Practice requirements before you’re actually registered to practice.

“Nurse” is a legally protected title in Ontario

Per Ontario’s Nursing Act, 1991 and the Regulated Health Professions Act, 1991, only members registered with CNO can use the titles nurse, Registered Nurse, Registered Practical Nurse, or any variation, abbreviation, or equivalent in another language. Referring to yourself as a nurse, or practicing nursing, in Ontario without being registered with CNO is illegal and can lead to prosecution, regardless of how much real nursing experience or education you have from another country. This is exactly why the registration process, however long it takes, isn’t optional paperwork; it’s what actually makes practicing here legal.

Your first step isn’t CNO, it’s NNAS

Per the National Nursing Assessment Service, internationally educated nurses complete a centralized credential assessment through NNAS before applying to any provincial nursing college. NNAS evaluates your nursing education and professional background and forwards a report to the college you’re applying to, CNO for Ontario, but NNAS itself doesn’t issue any licence or registration. It’s a required evaluation step, not the final approval.

What CNO actually requires after that

Per CNO’s registration guide for applicants from outside Canada and CNO’s next-steps guide for internationally educated nurses applying to the General Class, after your NNAS report, you’ll need to:

A realistic timeline

The full process for internationally educated nurses, from NNAS assessment through CNO registration, generally takes roughly 8 to 12 months, and can run longer depending on document verification delays and exam scheduling. Planning around that realistic timeline, rather than assuming registration will move as quickly as it did in your home country, helps avoid unnecessary financial strain while you wait.

What to actually do

  1. Start with the NNAS application and credential submission first, not a direct application to CNO.
  2. Once your NNAS report is complete, apply to CNO and identify which Evidence of Practice and Transition to Practice pathway actually fits your situation.
  3. Prepare for and schedule the NCLEX-RN and the jurisprudence exam as early as your NNAS timeline allows.
  4. Don’t use the title “nurse” or practice nursing in Ontario until you’re actually registered with CNO, no matter how strong your credentials from abroad are.

Frequently asked questions

I practiced as a nurse for years in Vietnam. Can I call myself a 'Registered Nurse' in Ontario while my application is being processed?

No. Under the Nursing Act and the Regulated Health Professions Act, only members registered with the College of Nurses of Ontario can use the title nurse, Registered Nurse, or Registered Practical Nurse, or an equivalent in another language. Using the title, or practicing nursing, before you're actually registered with CNO is illegal in Ontario, regardless of your real experience or credentials from another country.

What's the difference between NNAS and CNO?

NNAS, the National Nursing Assessment Service, is a national credential evaluation service; it assesses your international nursing education and professional background and forwards a report on it, but it doesn't issue any licence itself. CNO, the College of Nurses of Ontario, is the actual provincial regulator that reviews that NNAS report alongside exam results and other requirements, and decides whether to register you to practice in Ontario.

Jasmine, Former Ontario tenant and landlord, independent legal-education researcher, not a lawyer

I first ran into this problem as a tenant: I had a landlord who didn't follow the law, and watched friends and neighbors go through the same thing, usually just accepting it because they didn't know their rights or where to start. Years later, I became a landlord myself and saw the flip side: tenants who knew exactly how to exploit the law. That pushed me to actually learn the law properly, on both sides of the table, which is why I built Sovereign Shield: a free, offline-first app that walks people through real legal situations in plain English and Vietnamese.
