Terminal 1 was the brainchild of the Federal Department of Transport in the 1950's. Built over a period of six years, Aeroquay One as it was first known, opened in 1964 by then Prime Minister Lester B. Pearson. The new terminal was designed by famed architect, John Parkin, who created what was reported to be the first circular terminal in the world. Not only was Terminal 1 an architectural marvel, its interior was filled with modern furnishings as well as mosaics, sculptures, and paintings, designed by renowned Canadian architects of the day.

However, by the late 1960s, larger aircraft, more airlines and passengers put a strain on the function of the Terminal. Terminal 1 was later enlarged and joined by Terminals 2 and 3. After much planning and redevelopment, Terminal 1 was demolished in 2004, coinciding with the opening of the new Terminal 1, similarly revered for its architectural design.
