In the early 1960s, Canada witnessed the start of a major shift in the way we built our Central Business Districts, and it all started with the construction and completion of three buildings in Montreal; Place Ville Marie, the CIBC Tower and to a lesser degree, CIL House. These steel and glass monolithic structures rose high above anything else in the city and inspired many other developers to follow suite.

A few years later, developers in Toronto and Ottawa pushed the limits of their respective cities by building their own glass and steel office complexes nearly twice as high as anything else that came before.
In Toronto, the first phase of the Toronto Dominion Centre was completed in 1967; the start of Canada's iconic Financial District.

In Ottawa, although nowhere near the same scale as Place Ville Marie and TD Centre, local developer Robert Campeau was able to convince the City to break a long standing 120 foot limit. The result were 2 slick black office towers and a modernist hotel rising nearly 300 feet.

While Montreal, Toronto and Ottawa kept building more of these slick glass towers, other cities followed suite in the 1970s.
