Transport Canada Marine Safety and Security (TCMSS) wishes to inform the maritime community that new procedure have been developed to simplify the process to obtain a Candidate Document Number (CDN). It is now acceptable to submit a completed application with a single document provided it can attest the candidate’s identity and nationality.


Before obtaining any Canadian Maritime Document (CMD) issued by TCMSS under the provisions of Part 3 of the Canada Shipping Act 2001 (CSA 2001), a person must first apply for a CDN number, which is applicable but not limited to the following CMD s:

  • Certificate of Competency
  • Endorsement
  • Certificate of Service
  • Provisional Medical Certificate
  • Medical Certificate
  • Training Certificate
  • Application for Direct Examination - assessment
  • Application for Examination


As first articulated in Ship Safety Bulletin 05/2010, application for a CDN , has required two (2) documents as proof of identity. Following a review of this policy, TCMSS has determined that this requirement was an unnecessary burden to applicants.

By the issuance of this bulletin, TCMSS will accept one (1) document provided it can attest, the two required issues: candidate’s identity and Canadian nationality. A single document, such as a valid Canadian passport, can be used for this dual purpose. However, since many documents attesting Canadian nationality do not have a picture or a signature, for example birth certificates, it may still be necessary to submit two documents in order to attest Canadian nationality and identity.


Applicants for a CDN must complete the TCMSS form # 82-0701 – Application for a Candidate Document Number (CDN) in order to receive a CDN or update the personal information to the existing data base.

The form may be downloaded from the designated link: The completed application, together with proof of identity and nationality, must be submitted in person to the nearest TCMSS office, Please note, only identity documents issued by the Federal, Provincial or Municipal authorities will be accepted.
