Perhaps, Mr. Brison, I could pick up what Mr. Cook said around integrity measures. It is not to say that all the measures are merely housekeeping. They are very important. If they're not enacted, there would be significant revenue loss, but that doesn't mean that when you introduce them they're a policy change. They're an integrity measure to support the existing policy choices that are reflected in the act.
Another observation to make is that these proposed measures have now, for several years, been administered by the CRA as though they are law. Many taxpayers have either paid tax in accordance with the proposed measure or, to the extent it was an integrity measure, they've modified their behaviour and they've ceased and desisted in the kind of planning that was being undertaken that would have otherwise eroded the revenue line.
