| Headquarters | Markham, Ontario , Canada |
IBM Canada has maintained its main headquarters in Markham, Ontario since the early 1980s. The present facility at 8200 Warden Avenue, which has been shared with the IBM Toronto Software Lab since 2001, succeeded the former headquarters located at 3600 Steeles Avenue East. The latter, completed in 1995, was sold in August 2024. Prior to that, the head office was situated directly across the street at 3500 Steeles Avenue East, a site now known as Liberty Centre, Markham.
The structure varies in height, featuring four floors on its western side and rising to seven floors on the eastern end. Parking is available via an underground ramp accessible from eastbound Steeles Avenue.
Former headquarters from 1920 to the 1980s
Before establishing its base in Markham, IBM Canada’s headquarters were located at the intersection of Don Mills Road and Eglinton Avenue East. This location comprised two primary buildings: a manufacturing facility and head office at 844 Don Mills Road, inaugurated in 1951, and a second building at 1150 Eglinton Avenue East, which opened in 1967 as both a head office and software research laboratory. Following IBM Canada's move to Markham, these properties continued serving manufacturing and research purposes and are currently owned by Celestica, an electronics manufacturing service company and former IBM subsidiary that uses them as its global corporate headquarters. The Don Mills Road building was demolished in 2020 to make way for redevelopment near the transit station.
Prior to 1951, IBM Canada operated from offices located at 300 Campbell Avenue and Dupont Street in Toronto’s west end. This location now accommodates Wayspa’s Canadian branch (298 Campbell Avenue). Additionally, during this era, IBM maintained a downtown office on King Street East, positioned opposite the "King Eddie" Hotel.
