One Bloor

One Bloor is a mixed-use skyscraper at the prominent intersection of Bloor Street and Yonge Street in downtown Toronto. Originally planned under the name One Bloor East, the building was realized by Great Gulf Homes after several changes in concept and a change of ownership. The project's history began in 2007 with a proposal by Bazis International, which was abandoned due to financial difficulties during the global credit crunch. After the site was sold to Great Gulf, the design was reworked; the height was initially reduced but later raised back to 75 floors thanks to strong sales. At a final height of 257 meters, the tower is among the tallest residential buildings in Canada.

Architecturally, the building was designed by Hariri Pontarini Architects. It combines residential space with a six-story podium that offers more than 9,300 square meters of retail space. The sixth and seventh floors house spacious, resort-style amenity areas as well as a large outdoor terrace designed as a recreation space. The complex includes several hundred residential units and was at one point the subject of controversial debate when a well-known fast-food chain opened on the ground floor. For visitors, the building is of interest mainly for its striking silhouette on the city skyline and the retail space in the podium, which complements the lively surroundings along Yonge Street.
