Architect(s) : Gordon McKinstry

The Canadian Broadcasting Corporation prepared the plans and supervised the construction of this pavilion and is managing its operation in collaboration with the Expo 67 management.

During the Exposition, all broadcasters who wish to do so can produce radio and television programs in the Centre, which will be transmitted by satellite, over-the-air networks and magnetic or videotape, for millions of Canadian and foreign listeners. These programs cover the events of Expo, present aspects of Canada, and generally entertain listeners and viewers.

The International Broadcasting Centre is open to Expo visitors.

Through an elevated walkway with large windows, the public can watch a live television play, see the director at work in the production room and the technicians operating the complicated electronic equipment needed to make television programs, and see the sets being set up.

One of the most remarkable aspects of the building is a 175 x 80 foot terrace where an open-air radio studio has been set up, with an exhibition designed to illustrate the role that radio and television play in everyday life.

The Centre has the following production facilities:

The Large Studio: 100 feet by 70 feet, 3 colour cameras, 250 tiered seats, overall height 60 feet, headroom 35 feet. Fully equipped rooms for make-up, costume storage, sewing. There is also an artist's lounge and dressing rooms.

Studio 67: 55' x 40', 2 colour cameras, 16' clear height. Same facilities as above.
