Please download the form below and complete Section 1 before submitting your request either by email to, by fax to 416-961-6028, or by mail to our office. Be sure to include your first, middle, and last name(s), along with any previous names, and your six-digit CDHO registration ID number on the form.

If the regulatory body or educational institution has a specific form that they want you to use, you will need to submit both their form and the CDHO form for completion. Please ensure that the name and address where the completed form is to be sent is accurate, since we do not verify this information on our end before sending it out. The Certificate of Professional Conduct will be sent by mail directly to the specified organization, unless you have indicated in your request that it is to be sent to you or to be sent by any other means such as email or fax.

A copy of the certificate will be mailed to you at the address we have on file. Please ensure that your contact information is up-to-date in your Self-Service account. Past registrants can email an updated address for us to use for this purpose.

The fee is $15 per request, payable online in your Self-Service account or you can submit a certified cheque or money order to our office for payment.
