CIBC Square (known during early stages of development as Bay Park Centre) is an office complex under construction in the South Core neighbourhood of Toronto, Ontario, Canada. The complex, located on Bay Street south of Front Street, is a joint development of Ivanhoé Cambridge and Hines. It will serve as the new global operational headquarters for the Canadian Imperial Bank of Commerce (CIBC), consolidating approximately 15,000 staff from several CIBC-tenanted buildings in the Greater Toronto Area, including its existing headquarters at Commerce Court. The complex also includes the Union Station Bus Terminal constructed on behalf of Metrolinx for GO Transit and other inter-city bus services, connected directly to Union Station. The complex will also include a one acre park elevated over the rail corridor.
