In the 1960s, Yorkville flourished as Toronto's bohemian cultural centre. It was the breeding ground for some of Canada's most noted musical talents, including Joni Mitchell, Neil Young and Gordon Lightfoot, as well as then-underground literary figures such as Margaret Atwood, Gwendolyn MacEwen and Dennis Lee. Yorkville was also known as the Canadian center of the hippie movement. In 1968, nearby Rochdale College at the University of Toronto was opened on Bloor Street as an experiment in counterculture education. Those influenced by their time in 1960s-70s Yorkville include cyberpunk writer William Gibson. Its domination by hippies and young people led MPP Syl Apps to refer to it as "a festering sore in the middle of the city" and call for its "eradication." Joni Mitchell captured a colorful impression of the nightlife scene on Yorkville Avenue in her song "Night in the City". The hippie scene was also depicted in the National Film Board of Canada documentary Christopher's Movie Matinée in 1968. After the construction of the Bloor-Danforth subway, the value of land nearby increased as higher densities were allowed by the City's official plan. Along Bloor Street, office towers, the Bay department store and the Holt Renfrew department store displaced the local retail. As real estate values increased, the residential homes north of Bloor along Yorkville were converted into high-end retail, including art galleries, fashion boutiques and antique stores, and bars, cafes and eateries along Cumberland Street and Yorkville Avenue. Many smaller buildings were demolished and office and hotels built in the 1970s, with high-priced condominium developments being built in subsequent decades. Demographics Attractions Shopping and commerce The Mink Mile shopping district is located on Bloor Street, and includes office buildings with retail stores in the bottom one or two floors. The main streets of Avenue Road and Bay Street north of Bloor are similarly developed. North of Bloor, on Yorkville and Cumberland streets, between the main arteries, the character changes to smaller buildings containing art galleries, first-floor retail and restaurants. Further north still are single-family detached and semi-detached homes dating to the 19th century. Yorkville has shopping, restaurants, Yorkville Village mall, and the first five star hotel in Canada. Hotels in include the InterContinental Toronto Yorkville, Four Seasons Toronto, Park Hyatt Toronto, Hazelton Hotel, Windsor Arms Hotel, the Residence on Bay, and the Toronto Marriott Bloor Yorkville Hotel.
