There's some latitude for departments to reallocate funding within their own budgets to meet requirements. Speaking for myself, I can reallocate. I can move staff from one area to another without going to Treasury Board. I can look at my program and how I want to deliver it most efficiently and shift staff around within my own purview, as other departments can. Not every single thing needs Treasury Board approval.
