IBM Canada Head Office Building

IBM Canada's head offices are currently located in Markham, Ontario and have been there since the early 1980s. The current building IBM occupies is located at 3600 Steeles Avenue East and was completed in 1995. IBM Canada's previous head office was located across the street at 3500 Steeles Avenue East (now Liberty Centre, Markham).

Former head offices 1920-1980s

Prior to the 1980s, IBM Canada was located in a sprawling complex at Don Mills Road and Eglinton Avenue East. There are two main buildings at this site. The building located at 844 Don Mills Road was IBM's Canada manufacturing plant and head office and opened in 1951. After many additions to this building a second building on this site opened in 1967 (1150 Eglinton Avenue East) which became the head office and software research lab. When IBM Canada's head offices relocated to Markham, Ontario from Don Mills, their old site continued to operate as a manufacturing and research facility. Both facilities are now owned and operated by Celestica, an electronics manufacturing service provider and former IBM subsidiary, as its global corporate headquarters.

Prior to 1951, IBM Canada offices were located on 300 Campbell Avenue and Dupont Street in the city of Toronto's west end.[1] The plant is now home to Wayspa's Canadian operations (as 298 Campbell Avenue). During this period, and well into the 1950s, the company also maintained a downtown office suite located on King Street East immediately opposite the entrance to the famous "King Eddie" Hotel.

New tenants in former Don Mills head office

The Don Mills location is now the main head office and a manufacturing location for Celestica. Celestica was created in 1993 by IBM Canada, during a difficult financial period where many assets were sold off and various means were used to downsize staffing levels.

The IBM software development facilities were not transferred to Celestica and were eventually relocated to the IBM Toronto Software Lab at 8200 Warden Avenue in Markham in 2001.

International Business Machines Corporation (IBM) is an American multinational information technology company headquartered in Armonk, New York, with operations in over 170 countries. The company began in 1911, founded in Endicott, New York, as the Computing-Tabulating-Recording Company (CTR) and was renamed "International Business Machines" in 1924.

IBM produces and sells computer hardware, middleware and software, and provides hosting and consulting services in areas ranging from mainframe computers to nanotechnology. IBM is also a major research organization, holding the record for most U.S. patents generated by a business (as of 2019) for 26 consecutive years. Inventions by IBM include the automated teller machine (ATM), the floppy disk, the hard disk drive, the magnetic stripe card, the relational database, the SQL programming language, the UPC barcode, and dynamic random-access memory (DRAM). The IBM mainframe, exemplified by the System/360, was the dominant computing platform during the 1960s and 1970s.

IBM has continually shifted business operations by focusing on higher-value, more profitable markets. This includes spinning off printer manufacturer Lexmark in 1991 and the sale of personal computer (ThinkPad/ThinkCentre) and x86-based server businesses to Lenovo (in 2005 and 2014, respectively), and acquiring companies such as PwC Consulting (2002), SPSS (2009), The Weather Company (2016), and Red Hat (agreement announced in October 2018, actual acquisition to be in the second half of 2019). Also in 2014, IBM announced that it would go "fabless", continuing to design semiconductors, but offloading manufacturing to GlobalFoundries.

Nicknamed Big Blue, IBM is one of 30 companies included in the Dow Jones Industrial Average and one of the world's largest employers, with (as of 2017) over 380,000 employees, known as "IBMers". At least 70% of IBMers are based outside the United States, and the country with the largest number of IBMers is India. IBM employees have been awarded five Nobel Prizes, six Turing Awards, ten National Medals of Technology (USA) and five National Medals of Science (USA).
