Located on the southeast corner of Yonge Street and Colborne Street, 55 Yonge is a mixed-use tower that will include nearly 500 new residential units. The tower would be used for commercial office and residential purposes, with two full storeys of retail.

Atop the retail base would be a podium containing 13 levels of office space, which replaces the offices that currently stand at 53 and 55 Yonge, and the residential tower.

“With this rezoning application, we are proposing to redevelop the site with a new landmark commercial-residential building—a building that will provide a significant architectural contribution to this section of Yonge Street, one of the city’s iconic destinations and most important thoroughfares,” says the developers.

The building is designed to include approximately 13,000 square metres of retail space, 16,700 square metres of office space and mix of studio, one-bedroom, two-bedroom and three-bedroom units.

The developers say they’re using a “cohesive and contemporary high-rise design” for the multi-use skyscraper. Currently, the lot is occupied by two office buildings, including a 12-storey building 1958 by Canadian Modernist architect Peter Dickinson and by Page + Steele Architects. 

The developers of 55 Yonge has published a website seeking feedback on the Yonge Street site. There is no planned date for construction at present.
