The IBM Toronto Software Lab is the largest software development laboratory in Canada and IBM's third largest software lab. Established in 1967 with 55 employees,[1] the Toronto Lab, now located in Markham has grown to employ 2,500 people. These employees develop some of IBM's middleware.[2] Some of these include Db2, WebSphere Commerce, WebSphere Customer Center, Tivoli Provisioning Manager, IBM i compilers, and Rational Application Developer.
Originally located in a building at 1150 Eglinton Avenue East in Toronto, the software lab was relocated to Markham on September 11, 2001. The former building was subsequently used by Celestica.[3]
