Let me respond to the second question first.
Before you arrived, I was explaining that my organization really is focused on the international questions, not on Canadian domestic tax law or tax practices.
In response to your first question, when James Henry was here, who you met—he was the lead researcher on an enormous study—he suggested that Canada follow the lead of many other countries to estimate and publish what the tax gap is. Many countries, the United States for example, provide an estimate of what tax revenue authorities think they're missing. So his recommendation was that, indeed, Canada should follow that practice.
