Getting registered as an RDH in Ontario is a defined process. Five steps, three organisations, and a total bill that most people badly underestimate before they start.
None of it is complicated. It is just unforgiving about deadlines, and the deadlines are spaced out in a way that punishes anyone who plans as they go. Miss one exam application window and you have lost four months.
This walks through the whole thing as it stands in 2026. Which programs qualify, what the national exam costs and when it runs, what the College actually requires, what you pay at each stage, and how long it realistically takes. There are separate sections at the end for hygienists already registered in another province and for anyone educated outside Canada, because those routes genuinely differ.
The five steps
- Graduate from an accredited dental hygiene program
- Pass the National Dental Hygiene Certification Examination
- Apply to the College of Dental Hygienists of Ontario
- Pass the CDHO jurisprudence examination
- Hold current CPR at the Basic Life Support level and professional liability insurance
You cannot practise, or call yourself a dental hygienist, until CDHO issues your certificate. The title is protected in Ontario.
Step one: an accredited program
Your program has to be accredited by the Commission on Dental Accreditation of Canada. An unaccredited one drops you into a much longer and considerably more expensive route, so check accreditation before you enrol rather than after.
Studying in Ottawa
Algonquin College runs the main English language option: an Ontario College Advanced Diploma in Dental Hygiene, a three year credential delivered over roughly two and a half years, accredited by the Commission on Dental Accreditation of Canada. Graduates are eligible to sit the national certification exam. Fall is the main intake and it is competitive.
La Cité runs the French language program. In Ottawa specifically that is worth thinking about seriously, because bilingual hygienists have a measurable pay advantage in a market that takes in Vanier, Orleans, Gloucester and the Gatineau side of the river.
Budget beyond tuition. Algonquin puts supplies and clinical items at roughly $11,500 across the program, plus about $1,250 for certification and registration fees. Instruments and loupes are most of that and none of it is optional.
A word on length, because it comes up constantly. Dental hygiene in Ontario is not a short program. Three years of full time study including clinical placement is the standard. Anyone advertising a dramatically faster route to Ontario registration is describing something other than the accredited diploma pathway.
Step two: the national exam
The NDHCE is run by the Federation of Dental Hygiene Regulators of Canada and it is the national entry to practice examination. Ontario requires it.
It costs $850 plus tax, which is 13 percent HST here, and $62 of that is non refundable. The full fee schedule also covers the things nobody budgets for: late registration at $150, preparatory tests at $37.50 each, rescoring or an appeal at $206. Withdrawing fifteen or more business days out costs you $62. Withdraw later and it is $310. Inside two business days there is no refund at all.
The exam runs three times a year, roughly January, May and September. Current dates are:
Step three: applying to CDHO
The application fee is $50.
The General Certificate of Registration is $415, dropping to $207.50 if you apply within twelve months of graduating. That new graduate discount is worth $207.50 and it expires, so do not let the paperwork drift. The full fee list is on the CDHO site.
You will need proof of eligibility to work in Canada, a Canadian police record check at Level 1 minimum and no older than a year, proof of graduation, your exam result, proof of professional liability insurance meeting CDHO’s minimums, and a set of declarations covering criminal charges, findings of professional misconduct, failed exam attempts and academic integrity matters.
Everything has to be in English or French. Anything else needs an official translation, at your cost.
Two timing details. Your application stays valid for one year from the date you pay, and CDHO targets approval within ten business days of a complete submission. Complete is doing a lot of work in that sentence. Almost every delay is a missing document rather than slow processing.
Step four: the jurisprudence exam
Every applicant has to pass CDHO’s jurisprudence examination, which tests whether you understand the legislation governing dental hygiene practice in Ontario.
The format is generous. Multiple choice, open book, 80 percent to pass, unlimited attempts within a year.
People still fail it. Open book is not the same as easy, and the questions come from the Regulated Health Professions Act, the Dental Hygiene Act, CDHO regulations, the standards of practice and the record keeping requirements. If you have not read the source material before you sit down, having it open in front of you will not help, because you will not know where to look.
Step five: CPR and insurance
CDHO requires CPR at the Basic Life Support level, with both theory and a hands on practical component. An online only certificate does not meet the standard. Keep it current, since it is tied directly to your ability to practise.
Professional liability insurance is required for a General Certificate, and you submit a copy of the policy when you register and again at every renewal. New graduates should check their student association membership first. The Ontario Dental Hygienists’ Association student membership commonly includes free malpractice coverage valid for the rest of your graduation year, which is worth using.

Varies, often free in your graduation year
A new graduate who applies promptly is looking at roughly $1,400 to $1,600 from exam registration through to certificate, on top of tuition and supplies.
How long it takes
Three years of study. Then one to four months waiting for the next exam sitting, depending on when you finish. Then a few weeks for results. Then around ten business days at CDHO once your file is complete.
Exam timing is the variable that catches everyone. A September graduate who applies for the January sitting will not be registered until February at the earliest. Somebody who planned backwards from the exam calendar while still in their final year can cut months off that.
If you are already registered in another province
Labour mobility makes this route much faster.
CDHO runs an As of Right stream that lets dental hygienists currently registered in another Canadian province or territory start practising in Ontario while their application is reviewed, subject to conditions and a six month window.
You will still need proof of eligibility to work in Canada, a Canadian police record check, a certificate of standing from every regulator you have held registration with, and proof of liability insurance. You will still sit the jurisprudence exam, because it covers Ontario specific legislation that your existing registration says nothing about.
What you generally will not have to do is rewrite the national certification exam.
One note for anyone moving to Ottawa from the Quebec side: the regulators are entirely separate. Practising in Ontario requires Ontario registration no matter how short the bridge is.
If you were educated outside Canada
This route is longer and considerably more expensive, and it is better to know that at the start.
Graduates of non accredited and international programs go through an assessment process first. CDHO’s published fees for that pathway are steep: $800 for an educational credentials assessment, $675 for a written assessment, $1,500 for a clinical competency evaluation, and $150 to appeal a clinical result.
Stack those on top of the standard exam and registration fees and an internationally educated applicant is facing roughly $4,000 or more in assessment and registration costs alone, before any refresher coursework. Where a refresher is required it has to be finished within eighteen months before registration.
It is a real pathway and people complete it every year. Budget honestly and contact CDHO early, because the assessment sequence is where the time goes.
Staying registered
Registration is annual and the deadline does not move.
Renewal runs from October 15 to December 1 through the CDHO self service portal. A General or Specialty certificate is $415. Non practising is $215. Miss December 1 and there is a $100 late penalty on top.
At renewal you submit your current liability insurance policy, and you are expected to be meeting your quality assurance obligations, which include ongoing professional development and participation in the College’s QA program.
Budget the $415 every single year. It is the most commonly forgotten cost in the profession.
What you can earn once you are registered
In Ottawa, Job Bank reports a median of $45.00 an hour for dental hygienists, on a range from $35.00 to $51.00. Indeed puts the average higher at $53.69, drawn from job postings and user submitted salaries.
New graduates in Ottawa generally start between $38 and $44, with bilingual candidates and anyone covering evenings or Saturdays landing at the top of that. Relief and temp shifts pay more per hour, commonly $55 to $70, in exchange for no guaranteed hours and no benefits.
The full breakdown is in the Ottawa dental hygienist salary guide, and the Ontario wide picture covers regional variation if you are weighing up where to settle.
A note for new graduates
The gap between passing your exam and landing a permanent role you actually want is usually a few months, and it is the point where a lot of new hygienists take the first offer that appears rather than the right one.
Relief work is a reasonable way to bridge that. It puts you in five or six different practices in your first couple of months, which is the fastest education in how differently clinics run that you will ever get, and it means you are not negotiating your first permanent contract from a position of needing it immediately. Fairly verifies your CDHO registration once per year rather than making you send it to every practice separately, and you set your own rate rather than taking whatever is offered. If you want a sense of how relief work actually operates day to day, Temp Dental Hygienist Jobs in Ottawa covers it honestly, downsides included.
Frequently asked questions
How long does it take to become a dental hygienist in Ontario?
About three years for the program, plus one to four months waiting for the next national exam sitting, plus a few weeks for results and roughly ten business days at CDHO. Planning backwards from the exam calendar is the single best way to shorten it.
What does registration cost?
For a new graduate applying within twelve months of graduation, roughly $1,400 to $1,600 all in: $850 for the national exam, $50 application fee, $207.50 for the certificate, plus a police record check and CPR certification. Tuition and supplies are separate.
Do I have to write the jurisprudence exam if I am already registered elsewhere in Canada?
Yes. It covers Ontario specific legislation and applies regardless of where else you hold registration. Open book, multiple choice, 80 percent to pass, unlimited attempts within a year.
Where can I study dental hygiene in Ottawa?
Algonquin College offers an accredited Ontario College Advanced Diploma at its Ottawa campus, and La Cité offers the French language program. Both lead to eligibility for the national exam.
What CPR level does CDHO require?
Basic Life Support, with theory and a hands on practical component. Online only certification does not qualify.
Can I work while my application is processed?
If you are currently registered in another Canadian province or territory, the As of Right stream allows it subject to conditions. New graduates and internationally educated applicants have to wait for the certificate to be issued.
When is renewal?
December 1 each year, with the window opening October 15. A General or Specialty certificate is $415 and there is a $100 penalty after the deadline.
