The Toronto-Dominion Centre

In 1962, the Toronto-Dominion Bank and a development company owned by the Bronfman family announced they would jointly develop a huge combined property that included TD's celebrated 1913 Beaux-Arts headquarters. They hired Ludwig Mies van der Rohe — one of the last projects the modernist master designed before his death in 1969 — working with local firms John B. Parkin Associates and Bregman + Hamann.

Steel, glass, and a changed skyline

The initial phase comprised three buildings: the 56-storey TD Bank Tower, completed in 1967; a one-storey Banking Pavilion, completed in 1968; and the 46-storey Royal Trust Tower, completed in 1969. The complex is a classic example of Mies's International Style, emphasizing structural clarity and open, flowing spaces built from steel and glass — the same architectural language behind his 1957 Seagram Building in New York. The arrival of the twin towers signalled a dramatic shift in the city's prevailing style: for the first time, a major commercial development took over almost an entire city block, and a high-rise of steel and glass became Toronto's tallest building.
