Agreed on if there are pieces the city is currently spending on that are provincial responsibility then make those cuts right off the top. It's certainly a nice to have but doing more harm than good at this point in terms of what it is costing existing Edmontonians or how the city of Edmonton is viewed for affordability in the metro area (Cities, towns, & counties are competing for residents and businesses after all).
Regarding infrastructure deficits if this is the case I think they need to show that very clearly and make a distinct multi year shift away from building new infrastructure into investing in what we currently have.
The increases are so big and flying way above what we are seeing with inflation currently, I just don't think they can be accepted as there is no clear plan to bring them under control. The cuts will need to be painful and ideally most would agree we wouldn't want to see them. Some ideas that need to be considered in my opinion (no expert on the subject but believe in at least making suggestions):
Blatchford - Get out of the business, stop spending on it and sell what can be sold unless they can clearly indicate this is a revenue generator
Fees - Need to look at increasing fees for services like transit (fuel was specifically mentioned as a cost pressure in the article), rec centers and other public facility user fees should also be increased.
Facility Closures - Take a analysis of your worst performing or oldest leisure facility and/or library and make the difficult call to close it. Will have some unhappy folks and doesn't seem fair to pick one but looked at the rec centres the city has and noticed Eastglen leisure centre is a older looking facility and quite close to the newer Commonwealth rec centre. Not a popular thing when considering they are currently building a new rec facility out west but need to deal with the current reality.
Partnerships - We saw the recently announced Booster Juice deal with Terwillegar rec center. Where else can more ad revenue come in (i.e. Edmonton conference center).
