First Canadian Centre
First Canadian Centre is an office tower in Downtown Calgary, Alberta, Canada. Located at 350 7th Avenue SW, it stands at 167 meters (548 ft) or 41 storeys tall. The skyscraper has a floor area of 48,275 m 2 (519,627.8 sq ft) and was build in the international and late modernist architectural style. The Bank of Montreal occupies most of the ground floor with a large retail bank branch.

History
It was designed by Bregman + Hamann Architects, and was the tallest building in Calgary (surpassing Scotia Centre) when it was completed in 1982. Original plans called for a two tower complex, with this tower being the first of the two tower project. The second tower would have had 64 storeys. A downturn in the local economy at that time forced plans for the second tower to be shelved. However, with the recent boom in Calgary, the vacancy rate in the downtown core has dropped to 0.5 per cent, the lowest in North America. This has created a highly rumoured resurrection of the second tower, as a land use amendment has been submitted to city council for approval.
