Bell Canada acquired 100 percent of Northern Electric in 1964; starting in 1973, Bell's ownership stake in Northern Electric was diminished through public stock offerings, though it retained majority control. In 1983, as a result of deregulation, Bell Canada Enterprises (later shortened to BCE) was formed as the parent company to Bell Canada and Northern Telecom. As a result of the stock transaction used by Northern Telecom to purchase Bay Networks, BCE ceased to be the majority owner of Nortel, and in 2000, BCE spun out its share of Nortel, distributing its holdings to its shareholders.
