Client Identification Database ( CID) 

DID YOU KNOW?
As of 2025, Transport Canada Requires Each Operator to Have A CID Number

What Is a CID?

Prior to Transport Canada initiating the review, queueing, or approval process for your organization’s TDG manual, training program, or certificates, your assigned Transport Canada inspector must have your organization’s 2025 Client Identification Database number on file.
The CID is Transport Canada’s official mechanism for identifying organizations involved in dangerous goods activities and for understanding the nature and scope of those activities.

How Does a CID Assist Your Organization?

It ensures that submissions are correctly associated with your organization and directed through the appropriate regulatory oversight channels.
For this reason, completion of the CID registration process is a prerequisite to the submission of TDG manuals or training programs to Transport Canada for approval, even once the documentation has been fully developed.
If your organization imports, offers for transport, handles, or transports dangerous goods in Canada, registration in the Client Identification Database may be required. Completing the CID questionnaire will determine whether registration applies to your operations and, where applicable, will result in the issuance of a CID number.
Completing this step in advance helps prevent administrative delays and supports a timely and efficient review process once your documentation is submitted.

What is Client Identification Database? 

Except as Per Transport Canada: 
"Public safety depends on Transport Canada knowing who is importing, offering for transport, handling, or transporting (hereafter referred to as “DG Activities”) dangerous goods in Canada, what, when, and how, so we can mitigate risks.
In response to new regulatory requirements, Transport Canada is introducing a new registration database called Client Identification Database (CID) for persons or organizations involved in DG activities. CID will allow persons or organizations to register and will collect information about their DG activities. It will be used by Transport Canada to better assess risk, enhance overall safety measures, and facilitate effective communication and collaboration between Transport Canada and registered persons or organizations.
