Northwestel Inc. is the incumbent local exchange carrier (ILEC) and long distance carrier in Northern Canada. The company name is a portmanteau, sometimes spelled NorthwesTel, for Northwest Telecommunications.
Northwestel was established in 1979 by its owner, Canadian National Railways, spinning off the "northwest" operations of Canadian National Telecommunications (which is not to be confused with CNCP Telecommunications, a joint venture that CP Telegraphs and CN Telegraphs formed). The Newfoundland operation was, the same year, spun off as Terra Nova Tel (TNT). TNT was later purchased by NewTel Enterprises and merged with Newfoundland Telephone in late 1988.
Northwestel was sold to Bell Canada Enterprises (parent of Bell Canada) on December 1, 1988. Since then, Northwestel has become a direct subsidiary of Bell Canada, although still regulated (by the Canadian Radio-television and Telecommunications Commission (CRTC)) separately from Bell Canada, with its own method of regulation until 2007: rate of return. Northwestel, as of 2007, is regulated more closely like all other companies in Canada — price regulation and a split rate base — that is appropriate to the highly competitive environment in which they operate; Northwestel does not have a split rate base, however.
