Modernizing the CDS Issuer & Commercial User Experience

*** SUBJECT TO CHANGE ***

TMX-CDS has begun an initiative to modernize the critical infrastructure that underpins the Canadian capital markets' clearing, settlement and depository functions.

This modernization effort involves replacing CDS legacy applications with world-class technology solutions to deliver an effective, reliable, and streamlined client experience through our new CDSX application.

As a result of this initiative, the following Issuer Services are slated to be migrated to the new CDSX:

• ISIN Issuance
• ISIN Eligibility
• Notice of Record & Meeting Dates
• Holders of Record
• Unqualified Letter of Confirmation

As of April 28, 2025, you will be able to access these services by creating an account and logging into the new CDSX on the CDS.ca website.

To ensure current service levels are maintained through this migration, you can use the current applications and forms for these Issuer Services up to the cut off date and times stated below.
