I don't know the number. I do know that in the U.K. and Denmark especially, they send prepopulated forms out to people. They populate all 43 questions, let's say, or their similar list of questions—the ones they know the answer to. They send them out to the tax filer and ask them one question: Is this right? Is there anywhere we made a mistake? It gives an opportunity to the tax filer to then simply deal with it by exception. We don't do that in Canada.
Is there a reason we couldn't do it? There are two real reasons. The first is the number of questions and the need to answer a lot of questions that are not applicable in the first place, but that's in the act. We have to ask them and answer them. The second is timing. When do we really need to know these items? Other countries are more lax. They are more flexible in terms of saying, “Well, let us know within a certain period of time what has changed.” There doesn't have to be the immediacy that seems to be built into our system: “If your marital status has changed, we need to know immediately”, etc.
Those are the two big things: too many questions that are not relevant to refundable credits, and being a bit too timely in our approach.
