Updating your personal information
The CNSC maintains a registry containing the names and certification information of all certified exposure device operators (EDOs). Certified EDOs are responsible for maintaining current personal and contact information with the CNSC.
Submit the certification maintenance form, along with any additional documentation indicated in the form, to update the address the CNSC has on file (either mailing or email address) or to notify the CNSC of a legal name change.
When updating your legal name, please provide supporting documentation (e.g., copy of valid Canadian Government recognized photo ID complete with new name and signature; copy of marriage certificate/licence, etc.) along with the form.
Replacing a lost, damaged, or stolen certification card
It is the responsibility of any certified EDO to retain the CNSC-issued certified EDO card as proof of certification status.
If an EDO certificate is lost, stolen or damaged, a replacement must be obtained as soon as possible by completing and submitting a certification maintenance form to the CNSC.
If you are within 6 months of the expiry of your certification, you should still submit a request for replacement of the lost, damaged, or stolen card. This ensures you have proof of your certification status while preparing the renewal application and awaiting the CNSC decision on the renewal.
Where to submit
Submit the information to the CNSC by mail, fax or email:

Documents supporting your certification
It is the responsibility of the trainee or certified EDO to retain personal supporting documents of the ongoing training, examination and work activities they complete.
Supporting documents may include:
- work or training logs signed by a supervisor
- certificates of completion
- attestation letter from an employer
- other formal documents that show you have completed a training activity and the duration of that activity
Workers may be required to provide these records to the CNSC upon request. The CNSC does not maintain supporting document records for certified EDOs or trainees.
