By the late 1950s, planning was underway for what would become Canada's first fully-enclosed and climate-controlled commercial venue. John Graham, Junior, who had designed Seattle's NORTHGATE CENTER (North America's first shopping mall) was called in to conceptualize a centre city shopping complex for London, Ontario.

Opened to the public August 11, 1960, WELLINGTON SQUARE became not only the first interior mall in Canada but the first centre city shopping mall in North America...a concept copied in several cities in Canada and the United States during the 1960s and '70s.
