 Canada's densest community, St. James Town, was built in this era as a high-rise community of private and public housing in separate towers, also replacing a Victorian neighbourhood.These patterns changed dramatically beginning in the 1970s and gentrification began transforming once poor neighbourhoods, such as Cabbagetown, into some of the city's most popular and expensive real estate.Outside of the core, even new neighbourhoods experienced significant high-rise apartment building construction, as builders embraced the "towers in the park" design, invented by Le Corbusier.
