In the early 1950s, the offices for the federal agriculture department were scattered over 18 different sites, prompting the planning for the Carling Building, which began in 1954. Ottawa architect Hart Massey (1918–1996) designed the Sir John Carling in the 1960s and it opened in 1967, Canada's centennial year. In 2009, the building was deemed to be at its end-of-life and the agriculture offices were moved to the Skyline Office Campus on
Baseline Road. Despite local objections and its recognized heritage status,
deconstruction of the Carling Building began in April 2013, culminating in a controlled
building implosion on July 13, 2014. Afterwards, the concrete was pulverized and the site covered with topsoil and trees. Total cost for the demolition was CA$4.8 million. ==References==
