First Canadian Centre is an office tower in Calgary, Alberta designed by Donald C. Smith (1929–2014) of the New York firm Skidmore, Owings & Merrill. It was the second SOM project in Calgary after Toronto-Dominion Square, which is on the neighbouring block to the south. The project was intended to include 41-storey and 64-storey towers connected by a banking hall. However, due to the early 1980s recession, the taller tower was never completed.
