Calgary’s BMO Centre at Stampede Park is ready to welcome the world, officially becoming Western Canada’s largest convention centre with the grand opening of its 565,000 sq. ft. expansion. Following decades of planning and four years of construction, the over 1M sq. ft. Tier 1 convention facility opens its doors for the first time, not only creating an architectural landmark for Calgary but making gatherings even greater with the ability to host a scale of convention the city hasn’t been able to previously accommodate.
