About Bay-Adelaide Centre

Bay Adelaide Centre is the first phase in a multi-tower master plan in downtown Toronto. The tower is distinguished by its elemental, modernist form—a refined rectangular plan—and a prism-like skin of clear vision and fritted glass that make it one of the downtown core’s most transparent towers. At the top of the tower, the extension of the glass skin beyond the rooftop gives the building profile a distinctive identity.

The highly transparent tower base incorporates the historic façade of the National Building on Bay Street (Chapman and Oxley, 1926). The old façades maintain the street presence and roofline of the original building while greatly contrasting with the sleek all-glass façade of the new tower, which seemingly grew in behind it. The lobby features a major integrated public art project by the world-renowned artist James Turrell. The project also features a half-acre landscaped urban plaza with Gingko trees contributing a much-needed public open space to the central business district.
