The 1970s represented a turning point away from the International Style and Modernist planning. Brutalist architecture had been seen in Canada prior to the decade, but became more dominant in the 1970s with the backlash against the International Style. The style emphasized the reflection of the functional components of the interior in the exterior, along with geometric and sculptural uses of concrete on the interior and exterior of the building. It was a style used focally for institutional buildings for government, academic, and cultural uses, but also for high-rise residential and commercial buildings. At the same time, urban activists, architects and governments increasingly moved to influence development in favour of heritage preservation, historic view corridor preservation, and contextual sensitivity in scale and materials.
