Singling out this one point to comment that, at least for Calgary, the development levies don't even cover the cost of the infrastructure. There is a myriad of reasons for this (including legal court rulings around the definition of "benefit") but levies don't cover 100% of the bill. They are meant to cover 100% of the attributed benefit.
- dramatically lower development levies (i.e. cost recovery on infrastructure and nothing more) and repeal of land transfer taxes. The lost revenue could be managed through payroll constraint
Perhaps a better question would be, what do we actually need to levy for? Should we be charging levies for rec centres and libraries? They are very nice to have, and some would say essential to a higher quality of life. But, it is not like you can't live in a house if no library exists, but you definitely can't if no sewer main exists.
