The Calgary Bid Exploration Committee told the City Council in a presentation on Monday that C$2.2 billion in revenue from the Games would offset less than half their C$4.6 billion cost.
"I am confident when I say that the Board and staff at CBEC have diligently reviewed all aspects of bidding and hosting a prospective 2026 Games, and the numbers we are sharing today accurately represent the current situation," CBEC Chair Rick Hanson said in a statement.
The committee said Calgary's funding requirement was reduced given the 1988 Winter Games host had the ability to re-use existing venues, rather than build new ones.
The group said it had included post-Games endowments and facility operations costs in its budget estimates.
"One of the things we identified from looking at some prior Olympic Games was the failure to account for post-Games operation and maintenance of facilities in their budgets,” said Hanson. "While this adds cost, our Board felt it was a necessary addition to a prospective budget."
The Committee is scheduled to make its final recommendation to the city on July 24.
