Subject: Suspension of CSCN Report on Updates to Appendix A of the Central Office Code Assignment Guideline
Dear Kelly T. Walsh,
We are writing to inform you of the Commission’s decision regarding your request dated 2 March 2026. In your request, you sought a one-year extension to the deadline to file a report containing recommendations to update Appendix A of the Central Office (CO) Code Assignment Guideline to reflect new number-usage reporting requirements (the Audit Report). In Telecom Decision (TD) 2025-252 , the Commission requested that the Canadian Steering Committee on Numbering (CSCN) file the Audit Report by 26 March 2026.
Your request to extend the deadline to file the Audit Report from 26 March 2026 to 26 March 2027 was made on the basis that:
- The CSCN is currently focused on developing the thousand block pooling (TBP) schedule, as directed by the Commission in TD 2025-321 ;
- Informed updates to Appendix A would benefit from operational experience under TBP;
- As the new number-usage reporting measures and associated processes established in TD 2025-252 are still in their early stages, additional reporting cycles are needed to inform reliable thresholds, triggers, or escalation criteria to be considered in updates to Appendix A; and
- The CSCN considers the urgency of updating Appendix A to be low as it is unaware of an audit ever being conducted using the provisions of that appendix.
The Commission is satisfied that the request for additional time to develop the Audit Report is justified given the CSCN’s work in leading the development of the new TBP implementation schedule and the recent introduction of the new number-usage reporting measures.
In considering this request, the Commission notes that it recently launched Notice of Consultation (NOC) 2026-61 to examine whether and how it should leverage its authority under the Telecommunications Act to ensure that all numbers assigned by the Canadian Numbering Administrator, including those that are resold, are effectively accounted for. Given the potential for determinations arising from NOC 2026-61 to influence the development of the requested report, the Commission considers it appropriate to temporarily suspend, rather than extend, the deadline.
Accordingly, the Commission suspends the deadline to file the Audit Report. It will reconsider this matter following the conclusion of NOC 2026-61 and once the implementation of TBP has advanced sufficiently to allow for a more comprehensive development of the Audit Report.
If you have any questions, please do not hesitate to contact Étienne Robelin, Manager, Telecommunications, at Etienne.Robelin@crtc.gc.ca or 819-712-0199.
Sincerely,
Marc Morin
Secretary General and Executive Vice-President
