Change of Status

- Upgrade Inactive to General/Specialty Certificate of Registration

Registrants holding an Inactive Certificate of Registration cannot practise dental hygiene in Ontario. In order to practise dental hygiene, an Application to Change Registration Status form must be completed online in the  Self-Service Portal.  The signed form, supporting documentation (if required), and payment must be submitted to the College for processing.

For registrants who have practised outside of Ontario, Form B must be completed and submitted directly to the CDHO by the regulatory body in any jurisdiction in which they have practised.

Registrants who have not practised dental hygiene in a recognized jurisdiction within three years prior to applying, must successfully complete an approved refresher course, or assessment set or approved by the Registration Committee. Contact the CDHO for a list of approved instructors.

All registrants must maintain professional liability insurance which must include: a minimum of $1,000,000 coverage for each occurrence; annual aggregate coverage of no less than $5,000,000; and a deductible of no more than $4,000 per occurrence. In addition, requirements include: run-off coverage for a minimum of two years; the insurer must be licensed with the Financial Services Commission of Ontario or the office of the Superintendent of Financial Institutions Canada; and a sexual abuse therapy and counselling fund endorsement that,

  1. Provides coverage for therapy and counselling for every person eligible for funding under subsection 85.7(4) of the Code; and
  2. Provides coverage, in respect of each such eligible person, for the maximum amount of funding that may be provided for the person under the Act, for therapy and counselling as a result of sexual abuse by the Registrant. This coverage must be in place before being registered.
