IBM Canada Head Office Building

[1] IBM Canada's previous head office was located across the street at 3500 Steeles Avenue East (now Liberty Centre, Markham).

The building located at 844 Don Mills Road was IBM's Canada manufacturing plant and head office and opened in 1951.

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.
