Built in from 1980 to 1983 and designed by architect John B. Parkin,[1] the post modern complex consists of 15 floor and 10 floor towers connected by a glass atrium. The building is connected to the Toronto PATH underground pedestrian network.

After renovations completed in 2010 which brought the building up to LEED Gold standards, the first retrofitted building in Toronto to achieve the standard, the site has been partially used by CIBC.[2]
