I think a good example is what John has given you, a single window. It's a good idea in concept, something they were looking for. The implementation of it has been done. The take-up hasn't. Why? I think our friends at CBSA have described it.
I think in other instances, the system is working, and the challenge is demonstrating how it's working more effectively. Certainly, I think in the interactions we've had with most stakeholders, they are generally pleased that the beyond the border action plan was agreed to, and it has been, and it's being implemented.
