When telephone service was introduced in the eastern Northwest Territories, most of which is now the territory of Nunavut, created in 1999, in Frobisher Bay in 1958, Bell Canada nominally made it part of area code 418. In the 1960s and the 1970s, telephone service was introduced by Bell Canada at other locations in the eastern Northwest Territories and in locations along the Quebec Arctic coastline, as well as by Sotel, an independent company, in the James Bay region. Those non-diallable locations also became part of area code 418.
