Naturally, a brilliant question.
I think implementation has to be done right. If you need to take baby steps, take the baby steps. Experience shows that rushing to the finish line results in an inadequate structure and expensive mistakes, including a potential loss of life and removal from Canada. It's not worth that price. Take baby steps to get it right and have very strong transitional measures between old inventory and new.
My concern is with the refugee appeal division. That's been delayed a little too long. Is it possible, given the limited resources, to bring up both towers simultaneously? I'm not sure, but I'm very sensitive to the point.
