Our file number: 20-102724-615

The pilot for Clinical Trial regulatory activities in electronic Common Technical Document (eCTD) format concluded on August 31, 2019. Health Canada is pleased to announce that the pilot was successful. Therefore, implementation of Clinical Trials regulatory activities in eCTD format will begin immediately for the following:

The following regulatory activities and/or transactions are out-of-scope for filing in eCTD format:


The use of the eCTD format for Clinical Trial regulatory activities is optional. However, once a sponsor files a regulatory activity in eCTD format, all additional information and subsequent regulatory transactions for the same dossier (protocol) must also be filed in eCTD format. Sponsors cannot revert an eCTD dossier back to “non-eCTD electronic-only” format.

Use of common electronic submission gateway

All regulatory transactions in eCTD format (<10 GB) must be sent via the Common Electronic Submissions Gateway (CESG). Please refer to the CESG information page for details.
