code 867, all of the former 819 portion of the Northwest Territories, as well as the portion of the former 403 portion covering five exchanges, has become part of Nunavut. Area code 403, covering Alberta, has since been further split to create area code 780 for the northern two thirds of Alberta, including Edmonton. All existing prefixes stayed the same with the change to 867, with one exception. The conflict between 403 and 979 at Inuvik and 819–979 at Iqaluit was resolved by changing Inuvik from 403–979 to 867–777. A minor programming glitch allowed for a few weeks late in 1997 callers in the Inuvik area to dial 403-777 and reach Inuvik when they actually should have routed to Calgary, which appeared on customer's bills, along with the higher rate. Northwestel's proposal for a new regulatory regime was approved for 2007 to allow resale of local telephone service, but no competitors entered the market to avail themselves of the resale option. In 2011, facilities-based local service competition was approved by the Canadian Radio-television and Telecommunications Commission (CRTC) and so additional central office codes are now required for competitive carriers wishing to offer local service. The expense limits deployment so far to Whitehorse, Yellowknife, Inuvik, Behchokǫ̀, Aklavik and Hay River, four of which already have multiple prefixes. Communities that now have only one prefix are not likely to need a second prefix other than for local growth or the entry of a competitor (as in Aklavik and the twin Behchokǫ̀ communities, Rae-Edzo*). The sparsely-populated area is unlikely to exhaust numbers in the foreseeable future. However, in June 2021, the CRTC recommended implementing the three-digit code 9-8-8, which is already in use as a local exchange in the Yellowknife area, as the nationwide number for suicide prevention hotlines, which would imply the need to implement ten-digit dialing in area code 867. The CRTC decision followed the decision of the US Federal Communications Commission to adopt 9-8-8 as the number for the US National Suicide Prevention Lifeline. In August 2022, the CRTC finalized its implementation plans for 9-8-8, effective November 30, 2023; it accepted a request from Northwestel to make ten-digit dialing mandatory only in the Yellowknife area and optional elsewhere within the region as of May 31, 2023, in part because it would ease the process of communicating the transition to remote communities and in Indigenous languages. * Behchokǫ̀ has two separate
