BMO Centre Expansion

Western Canada’s largest convention centre welcomes the world

An architectural landmark—and a new precedent for world-class convention venues.


Another big boost to Calgary’s stature on the world stage

CMLC led the delivery of the BMO Centre’s $500-million expansion, which increased the facility’s total floor space to more than one million square feet and elevated Calgary to top-tier destination status in the global meetings and conventions market. Second to none in design and functionality, the architecturally spectacular expanded BMO Centre sets a new precedent for convention facility form and function.
