Certainly.
I'll start with the last. Clearly, corrections and justice and others are keenly engaged in these issues and recognize the challenge. They are looking at alternative processes for dealing with those who come into contact with the law. More broadly, though, in terms of prevention and engagement, there are community-based programs, specifically those focused on children, such as Canada's prenatal nutrition program, the action program for children, and Aboriginal Head Start. I'll address those issues as well.
In terms of your first question, short is one to two years, medium is three to five, and long is five-plus years.
