Nortel Networks Corporation, formerly known as Northern Telecom Limited and Northern Electric, was a multinational telecommunications and data networking equipment manufacturer headquartered in Canada. At its height, Nortel was one of the largest telecommunications equipment suppliers globally, producing a wide range of products for wireline, wireless, and enterprise networks. The company played a significant role in the development of digital switching and fiber optic transmission systems. However, following the dot-com bubble burst, an accounting scandal, and intense market competition, Nortel filed for bankruptcy protection in January 2009. Its assets were subsequently sold off to various buyers, leading to the cessation of its operations. Nortel's legacy includes its technological contributions and the significant impact its rise and fall had on the Canadian technology sector and global telecom industry.
Served as a major corporate headquarters and R&D center, overseeing significant aspects of global operations, strategy, and product development.
The Mississauga campus was a large, modern facility designed to house thousands of employees, featuring extensive R&D laboratories and office spaces, characteristic of major tech campuses.
Historically, Nortel was known for a strong engineering culture and innovation. It attracted top talent and was considered a prestigious place to work. In its later years, it faced challenges adapting to market changes, and internal culture was affected by financial difficulties and restructuring.
This location was central to Nortel's operations in its later years, representing its status as a global technology leader. Its presence was significant for the local economy and Canadian tech industry.
During its peak, Nortel Networks had a vast global presence, with operations, sales offices, and R&D centers in over 150 countries. Key functions supported globally included research and development for telecommunications hardware and software, manufacturing, sales and marketing, customer support, and professional services for telecom carriers, enterprises, and governments worldwide. Its international operations were crucial for its market leadership in areas like digital switching, optical networking, and wireless infrastructure.
