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.

Located at 350 7 Avenue SW in the city's downtown core, it stands at 167 metres (548 ft) or 41 storeys tall.

[1] The skyscraper has a floor area of 48,275 m2 (519,630 sq ft) and was built in the international and late modernist architectural styles.

All traffic was stopped by police during the night to allow concrete trucks to reign non-stop along Seventh Avenue.

With the National Energy Program slowing Alberta's oil and gas industry in the early 1980s, Dome's profits were hit hard and caused the company to withdraw from the tower's acquisition, which may have had a large effect for the tower's demise.
