I think we've covered enough comparables in this thread to conclude that the $70 million price tag attached to this one is ridonkulous.
The huge new centres built in Edmonton and Calgary have multiple swimming pools and multiple hockey rinks and other stuff like libraries. This is one pool, zero rinks and zero libraries. They are not comparable.
The pool will cost $35M. The other $35M is padding. That way the pool can wind up costing 2x what it should and the Mayor will still claim that it was on budget. Anything the might be left over can then be used to pay for more homeless shelters.
