The Toronto-Dominion Centre, or T-D Centre, is a cluster of buildings in downtown Toronto, Ontario, consisting of six towers and a pavilion covered in bronze-tinted glass and black painted steel, and serving as the global headquarters of the Toronto-Dominion Bank, as well as providing office and retail space for many other businesses. 21,000 people work in the complex, making it the largest in Canada. The project was the inspiration of Allen Lambert, former President and Chairman of the Board of the Toronto-Dominion Bank, with Phyllis Lambert recommending Ludwig Mies van der Rohe as design consultant to the architects, John B. Parkin and Associates and Bregman + Hamann, and the Fairview Corporation as the developer. The towers were completed at different times between 1967 and 1991, with one additional building originally built outside the campus and purchased in 1998. Part of the complex, described by Philip Johnson as "the largest Mies in the world," was designated as an Ontario heritage site in 2005.
