The CRTC has approved one but rejected another application on number portability. On Friday, the regulator released its decision on an application by Telus Corp. to “establish a special location porting zone (LPZ) within the Metro Vancouver area” so that residential and business subscribers can keep their phone numbers as they move within the area. “Implementation of the proposed LPZ would increase substitutability and competition between wireline, wireless and telephone service providers operating within the Metro Vancouver area,” the CRTC said in its decision, which was posted on its website. It added subscribers would “avoid the costs associated with other options” to keep their numbers when changing addresses outside their original exchange. Telus asked that the numbers be ported between 17 exchanges. The decision runs in contrast to another the CRTC released Friday, dismissing a similar application by the Public Interest Advocacy Centre (PIAC), the Consumers’ Association of Canada and the Council of Senior Citizens’ Organizations of British Columbia. In that application, PIAC asked that the regulator consider expanding the geographic boundaries of number portability in other parts of the country. It argued it would benefit consumers and that current local number portability policy undermines competition as Canadians move from wireline to wireless services. Interveners against that expansion brought forward the arguments, accepted by the CRTC, that such an endeavour “raised the prospect of significant complexity and feasibility challenges, and significant costs.” It also was determined that “there were no other groups of exchanges eligible for an LPZ that meet the criteria identified” in Telus’ application, they weren’t submitting applications to establish an LPZ in other locations and that there were “no locations that would be candidates for location porting expansion.” The CRTC said B.C. carriers should implement the porting zone within three months in the Telus decision.
