There's a cost estimate from the bid exploration committee for Calgary's potential bid. They expect the games to cost roughly $4.6B and be able to recoup $2.2B from the operation of the games (Tickets + IOC Funding + Sponsorship). Thus an anticipated need for $2.4B in additional funding from governments. Which, all told is a pittance at the Olympic scale, but no small amount of money to come up with when the provincial governements are running some pretty eye watering deficits right now.
The press release unfortunately does not offer a break down of where the $4.6B would need to be spent. I how much for security? How much and for which venues? The bid exploration committee's website doesn't have details on the facilities master plan yet. I'm particularly interested whether these number takes into account the new arena?
