Number one, you are quite correct. It's one thing to build the walls for affordability, but the supports must be in place.
For individuals with intellectual and developmental disabilities, the supports are for daily living, which vary depending on the needs of the individual. They range from a few hours a week for help with banking, groceries and what have you to one-on-one, constant support to make sure that they're not harming themselves or others in their quest to gain as much independence as possible in the community.
It really depends, but the bottom line is that funding for the agencies, which is generally a provincial responsibility, needs to be there and needs to be strong for the supports.
