How would you implement this type of program?
Tax incentives can mean a lot of things for the private sector and the public sector...whether it's a religious institution that owns a heritage building. How do you put the programs in place so that you can say it's going to depend on the value of the property, or is it going to be dependent on how much this typical organization has in its coffers?
How are you going to determine how the program is going to be structured? That's the complexity of establishing a program.
