First of all, to address the first part of your question, my officials confirm that no province has clawed back any of the Canada child benefit. When we were together last year, we asked them not to. They all confirmed that they wouldn't, and no province has introduced any clawback of the Canada child benefit, just to confirm that for you.
With respect to your second point, I'm assured that we are going to be looking at the impacts of the Canada child benefit through studies as we move forward. Clearly, what we want to do is ascertain that, in fact, the goals that we've set out are being achieved, but over the longer term we want to make sure it has the desired impact on improved outcomes for Canadian families.
