The 37,280 square metre complex is a prominent example of postmodern architecture in Canada, finished in 1987 by Jones and Kirkland.

The design was influenced by farmsteads which once occupied much of Mississauga[1] as well as historical features of city centres.

After the 1969 fire that gut the east wing, the Township offices were relocated once the 1 City Centre Drive was made available from developers of Square One.

[3] The firm was founded by UK architect Edward Jones CBE and US partner Richard Kirkland.

The Duke and Duchess of York were part of the opening ceremonies for the new civic centre in July 1987.

Mississauga resident Don Cherry who is most notable for being on Hockey Night In Canada and a Canadian icon added fuel to the fire when he stated that the new City Hall reminded him of his home town Kingston, Ontario because it looked more like a penitentiary than a City Hall.

It also features a wading pool/ice rink located on the south side of the building; to the west is the floral garden, often used for wedding pictures.

South of the complex is the five-storey Mississauga Central Library, one of the largest in the Greater Toronto Area.
