The facility estimates these numbers based on 95 events booked, with more than 87,000 delegates and 4,100 exhibitors.
Delegate spending will be $194 million, exhibitor spending $63 million and convention centre production at $12.5 million.
The facility will produce an estimated tax revenue of $103 million. Officials also estimate 3,540 jobs will be supported by the overall economic impact of the convention centre.
"Being a G8 capital, Ottawa needed a new convention centre that could accommodate large-scale events," stated OCC chair Jim Durrell.
"OCC is a ‘stay-at-home export' because it attracts business to our nation's capital that would otherwise go elsewhere. Not only is OCC doing well from a business perspective, but the citizens who live here benefit as well."
This past year, the facility hosted 40 conventions and 35,000 delegates with an economic impact of $83 million. These included the Liberal and Conservative conventions, Northern Lights 2012 and the NHL All-Star Weekend, as well as annual events such as the Ottawa Wine and Food Festival.
