One Canada Square Canada Square was completed and open for business. His Royal Highness The Duke of Edinburgh officially opened One Canada Square on the morning of 26 August 1991, and unveiled a commemorative plaque at the entrance to the building. Hundreds of construction workers attended the opening ceremony. The Duke of Edinburgh addressed some 800 invited guests, many of whom had been involved in the project. He spoke of the "large, airy space and clean, efficient office layout", as he declared the building ready for business. The attendees heard a specially-commissioned piece of music performed by a 30-strong choir. Paul Reichmann, Chairman
