Telecom Public Notice CRTC 2004-4

  Ottawa, 7 October 2004
  Establishment of a new CISC ad hoc committee for area code relief planning in British Columbia area code 250
  Reference: 8698-C12-200410861
  With this public notice, the Commission announces the establishment of a CRTC Interconnection Steering Committee ad hoc relief planning committee to examine options for providing relief to area code 250 in British Columbia. The Commission invites the public and telecommunications service providers to participate in the activities of the ad hoc committee.



On 10 June 2004, the Canadian Numbering Administrator (CNA) published the results of the latest General Numbering Resource Utilization Forecast (G-NRUF) for the various area codes in Canada. The results of the latest G-NRUF indicated that area code 250 in British Columbia was projected to exhaust in May 2009. To this end, there is a need to begin the area code relief planning process, which is being initiated through the release of this public notice.



In Approval of revised Canadian NPA Relief Planning Guidelines, Decision CRTC 2001-607,26 September 2001, the Commission established revised guidelines for the relief of area codes prior to their exhaust. The Canadian NPA Relief Planning Guidelines (the Guidelines), as amended from time to time with the Commission's approval, provide the framework to be followed for addressing area code exhaust in Canada. The Guidelines establish a step-by-step process to be followed by the CNA and the relief planning committee, and also identify certain actions that are left to the Commission to address.


In accordance with the Commission-approved Guidelines, area code relief planning will be conducted in a public manner through the establishment of ad hoc committees of the CRTC Interconnection Steering Committee (CISC) called relief planning committees (RPCs), in order to increase public awareness and participation. The CNA, in its function as numbering plan area (NPA) relief planning co-ordinator, acts as a chair of these RPCs.


The NPA 250 RPC is responsible for developing a relief planning document which describes all options that might reasonably be pursued to implement relief for area code 250. The benefits and drawbacks of each relief option described will be clearly identified by the RPC and documented in an Initial Planning Document. The Initial Planning Document will then be forwarded to the Commission via the CISC process for inclusion in a public process, where the Commission will seek comments on the appropriate method by which relief will be implemented. The Commission will then render its decision.


The scope of relief planning activities is limited to the consideration of solutions related to the introduction of new numbering resources within a geographical area. Since area code relief planning does not impact local and long distance calling areas or rates, these issues are outside the scope of the processes described in this public notice.


On 13 September 2004, the CNA announced that the first meeting of the NPA 250 RPC will take place on 21 and 22 October 2004, at the Grand Okanagan Lakefront Resort and Conference Centre in Kelowna, British Columbia. For further information regarding the meeting logistics, and to request a copy of the Initial Planning Document and other related materials, parties are asked to contact the office of the CNA via or by calling (613) 563-7242.


Once the Commission has considered all public comments and has made a determination on a relief method and date for area code 250, the RPC will be called upon to develop a proposed NPA relief implementation plan for the area code. The relief implementation plan will be forwarded to the CRTC for approval, via the CISC process. If approved, all telecommunications service providers (TSPs) using, or intending to use, numbering resources in area code 250 will be required to execute the plan.


In preparation for these relief planning activities, the CNA should ensure that all central office (CO) codes in area code 250 are accounted for, and that all records for this area code, including local dial plans, are up to date. Where local dial plans have not yet been provided to the CNA, TSPs are required to submit their dial plans within 30 calendar days of this public notice.


In addition, the CNA should ensure that Part 4 forms have been received for all assigned CO codes in this area code as per the timelines set out in the Canadian Central Office Code (NXX) Assignment Guidelines. The CNA should initiate reclamation of any NXX assigned to any carrier that has not filed the appropriate documentation and that has not received an extension as per the guidelines.



Parties wishing to participate in the activities of the NPA 250 RPC must notify the Commission of their intention to do so by contacting the Secretary General by mail at CRTC, Ottawa, Ontario, K1A 0N2; by fax at (819) 994-0218; or by e-mail at, by 18 October 2004. Interested parties are to indicate in the notice their e-mail address where available. If parties do not have access to the Internet, they are to indicate in their notice whether they wish to receive a disk version of hard copy filings.


The Commission will issue, as soon as possible after the registration date, a complete list of parties and their mailing addresses (including their e-mail address, if available), identifying parties who wish to receive disk versions.
