Nortel Commercial 1994

 Nortel, formerly commonly known as Northern Electric and Northern Telecom, was a multinational telecommunications and data networking equipment manufacturer headquartered in Mississauga, Ontario, Canada. It was founded in Montreal, Quebec, in 1895 as the Northern Electric and Manufacturing Company. Until an antitrust settlement in 1949, Northern Electric was owned principally by Bell Canada and the Western Electric Company of the Bell System, producing large volumes of telecommunication equipment based on licensed Western Electric designs.

At its height, Nortel accounted for more than a third of the total valuation of all companies listed on the Toronto Stock Exchange (TSX), employing 94,500 people worldwide.

In 2009, Nortel filed for bankruptcy protection.
