The EY Tower (formerly known as the Ernst & Young Tower and 100 Adelaide Street West) is a skyscraper in Toronto, Ontario, Canada at 100 Adelaide Street West.[2] The building was designed by Kohn Pedersen Fox and WZMH Architects.[3]
At its 1928 opening, 100 Adelaide Street West, was the Concourse Building which was a 14-story Art Deco structure. The building tenant was the Toronto Industrial Commission, which promoted the city as a hub of finance and business in Ontario. The building was famous for its mosaics by Group of Seven member J.E.H. MacDonald.[4] The Concourse was designed by the firm of Baldwin and Greene.[5] Oxford Properties took control of the building in 1998 and released plans to replace the Concourse Building with a new tower.[6] The Concourse's defenders tried to find a buyer for the building, though Oxford refused to sell the site.[7]
The decision to demolish the Concourse Building was controversial, but the Toronto and East York community councils ultimately voted in favour of the demolition in May 2000, with a vote of 38 to 12.[8]
Oxford released plans for the new building on 17 June 2013.[7] The new proposal also announced that the building would be renamed from 100 Adelaide Street West, the street address of the site, to Ernst & Young Tower.[9] Ernst and Young, the primary tenant of the new building, will be leasing 225000square feet of office space.[9]
EY Tower is 617order=flipNaNorder=flip high, with 42 floors and a total area of 900000square feet.[10] The base of the new tower includes the south and east walls of the original Concourse Building and is integrated into the PATH as part of Oxford's Richmond-Adelaide Centre. The main tenants of the building are Ernst & Young, OMERS and TMX Group. In addition to a new public space and renovated entrance through the Concourse Building, the tower also features a 5000order=flipNaNorder=flip outdoor terrace on the 14th floor. The building is LEED Platinum certified.[11] The building was completed in 2017.[12]
After many stages of planning, the tower's construction started in July 2014.[13] The Tower was topped-out in June 2016 and opened in May 2017.[14] [15] [16]
