Toronto-Dominion Square, originally Oxford Square, is a full-block building complex in Calgary, Alberta built by Oxford Developments. The project was designed by Skidmore, Owings & Merrill of New York, with J. H. Cook and Associates as the architect of record. It is located on the block between 7 and 8 Avenues South and 2 and 3 Streets West. The structure consists of a five-storey base with two 35-storey towers. The south tower is named for the Home Oil Company and the north tower is named for Dome Petroleum. The base includes a large botanical garden called the Devonian Gardens. In 1980, SOM replicated the design concept in its Town Square in Saint Paul, Minnesota.
