Confederation Heights

Confederation Heights includes the Clarke Memorial Centre (RA Centre), the Taxation Data Centre (Canada Revenue Agency), 1500 Bronson Avenue (formerly Canadian Broadcasting Corporation and Communications Security Establishment's Edward Drake Building), the Sir Leonard Tilley Building (formerly Communications Security Establishment), Canada Post Place (Canada Post headquarters), the Sir Charles Tupper Building (Public Works Canada), Hog's Back Park, Vincent Massey Park and Mooney's Bay station.

Prior to the expropriation of the Merkley Brick Yard in 1954, the area had been a combination of woods, farmland, quarry and brickyard.

In 1959, the Fire Chief of Gloucester Township (the area was incorporated into Ottawa the following year) raised concerns that road traffic caused by the 1400 new workers commuting to Confederation Heights would interfere with the firefighters' ability to respond to fires from their station in Billings Bridge.

The plaque attached to its base read "Erected by Headquarters Staff of the Post Office Department to Commemorate the Centennial of Confederation July 26, 1967".

It was replaced by a new Canada Post headquarters building located in Confederation Heights at the corner of Riverside Drive and Heron Road.
