Canadian Steering Committee on Numbering

Mission Statement

The Canadian Steering Committee on Numbering (CSCN) is an open public forum established as a subtending Working Group of the CRTC Interconnection Steering Committee (CISC) to consider and resolve numbering resource issues. The CISC is a committee comprised of various industry representatives that was initiated to facilitate implementation of Telecom Decision CRTC 97-8, Local Competition. The mandate and administrative processes of the CISC are contained in the CRTC Interconnection Steering Committee Administrative Guideline. As per Appendix 1, Item 6, of those Guideline, the mandate of the CSCN is to undertake tasks related to numbering issues on matters assigned by the CRTC that fall within the scope of the CRTC jurisdiction. The mandate of the CSCN is further defined in Section 3 of the CSCN Adjunct to the CRTC Industry Steering Committee Administrative Guideline. This Adjunct also describes the administrative processes of the CSCN. To raise an issue at the CSCN, a participant may submit a completed Task Identification Form (TIF) to the CSCN for consideration using the CSCN TIF Template. Regulatory authority for the administration of domestic numbering resources by the CRTC is contained in section 46 of the Telecommunications Act.

The CRTC approved numbering resource assignment guideline are maintained on the CRTC Web Site.
