Thank you.
I don't see why you can't proceed with both. It seems to me that the private solution will be ready well before the public one. It is going to take the Brits five years, and that's five years from having decided what they want to do. We're not at the “deciding what we want to do” stage yet.
The prudent thing to do would be to eliminate the barriers to having the private sector solution work. Get some task group figuring out what kind of supplementary Canada Pension Plan we need to launch if this doesn't solve all the problems, but hold off on deciding absolutely whether you need to launch it until this has its opportunity. I am worried that the Canada supplementary plan will crowd this out as an alternative if both are made available at the same time.
