Establishment of a CISC ad hoc committee for area code relief planning for area codes 416 and 647 in southern Ontario

File number: 8698-C12-201011478

With this notice, the Commission announces the establishment of a CRTC Interconnection Steering Committee ad hoc relief planning committee (RPC) to examine options for providing numbering relief to the area served by area codes 416 and 647 in southern Ontario. The Commission invites members of the public and telecommunications service providers to participate in the RPC’s activities.


1.         On 1 April 2010, the Canadian Numbering Administrator (CNA) published the results of the latest numbering resource utilization forecasts.[1] The results indicate that area codes 416 and 647 are projected to exhaust by July 2015, which is within the prescribed 72-month time frame[2] for beginning relief planning activities.

2.         The Commission-approved Canadian Numbering Plan Area (NPA) Relief Planning Guidelines (the Guidelines) provide the framework for addressing area code exhaust in Canada. The Guidelines establish a step-by-step process to be followed by the CNA and relief planning committees (RPCs). The Guidelines require relief planning activities to begin if area code exhaust is projected to occur within the next 72 months.

3.         The telecommunications industry conducts area code relief planning in a public manner through an ad hoc RPC under the CRTC Interconnection Steering Committee (CISC). Part of the role of an RPC is to encourage public awareness and participation. Members of the public are encouraged to participate in the RPC’s activities.

RPC for area codes 416 and 647

4.         Since area codes 416 and 647 are projected to exhaust in 60 months, the Commission determines that there is a need to begin the area code relief planning process. With this notice, the Commission therefore establishes the ad hoc RPC for area codes 416 and 647 (the 416/647 RPC) under CISC and directs the CNA to chair this committee.

5.         The scope of the 416/647 RPC’s relief planning activities is limited to the consideration of solutions for introducing new numbering resources within the area currently served by area codes 416 and 647. Since area code relief planning does not affect local and long distance calling patterns or rates, these issues are outside the scope of the 416/647 RPC’s relief planning activities.

6.         All relief options contemplated by the 416/647 RPC, as well as its recommendations, will be considered by the Commission in rendering its decision on the relief measures to be adopted.

7.         In developing its recommendations, the 416/647 RPC is directed to set aside, at a minimum, 7 central office codes for initial code assignments for carriers already providing service in the area served by area codes 416 and 647, and 10 central office codes for initial code assignments exclusively for new entrants.

8.         The Commission considers that the 416/647 RPC may contemplate relief measures that would require some customers to change their telephone numbers. The Commission therefore encourages members of the public to participate in the activities of the 416/647 RPC.


9.         The CNA will announce the location and time of the 416/647 RPC’s meetings and will make all related documentation available on its website,, or by telephone, at 613-563-7242.

10.     Parties interested in participating in the activities of the 416/647 RPC (including receiving copies of all submissions) must notify the Commission of their intention to do so by filling out the online form or by writing to the Secretary General (by mail: CRTC, Ottawa, Ontario  K1A 0N2; by fax: 819-994-0218) by 20 August 2010 (the registration date). Parties are to provide their email addresses, where available. If parties do not have access to the Internet, they are to indicate in their notice whether they wish to receive disk versions of hard-copy filings.

11.     As soon as possible after the registration date, the Commission will post on its website a complete list of interested parties, their mailing addresses, and, if available, their email addresses, identifying those parties who wish to receive disk versions.
