Environment committee  I don't know. Mr. Hayes, could you answer the question?

Environment committee  If I could just add, Mr. Longfield, we are already incorporating the sustainable development goals into our work, but we can and we should be doing a better job. That is exactly our goal. Regardless of how we decide to structure or set ourselves up to manage our people, it doesn't mean we're taking away the importance of them.

Environment committee  When it comes to the kind of expertise we have within the office, we have CPAs, lawyers, economists, environmentalists, engineers, so many. We do have a pocket of rich experience and knowledge about the environment and sustainable development area, and we're trying to make sure that we broaden and expand it.

Environment committee  You are correct. We launched a countrywide search for the new commissioner of the environment and sustainable development at the end of October. What we have done so far to find—

Environment committee  I personally have not yet. They have communicated with me, and we are reaching out through our professional networks to make sure that people know we're searching.

Environment committee  As I mentioned earlier, while we do have a group that we call the commissioner's group, it is more of an administrative function because of who they report to within our organization's structure. Our performance audit practice has specialists from all fields.

Environment committee  I couldn't really tell you how many people are on a particular team, because as I said, we don't have people who are designated within a group. We have auditors who spend a good amount of their time working on performance audits that are issued under the banner of the commissioner of the environment and sustainable development, but it's not a group.

Environment committee  No, not at all, the group was not abolished. What we're doing is that we're taking the skills and specialties of people like Ms. Leach and Mr. McKenzie, who are here today, and spreading them out across our work. When we want to have sustainable development goals addressed in all of our work—

Environment committee  Thank you, Mr. Chair. Congratulations on your recent nomination to the chair of this very important committee. We prepared some slides and submitted them to the committee in preparation for our appearance today. I encourage you to keep them as reference tools for my office's mandate.

Public Accounts committee  I unfortunately don't have that. Maybe Philippe does, but really, where we're seeing the lost revenue is where the products are coming from a foreign vendor.

Public Accounts committee  I think you've categorized it well. That number is based on e-commerce that we looked at, and we did not look at physical goods that would enter through the low-value dollar shipment program. Yes, if you incorporate both, then this number is, as we said earlier, on the low end.

Public Accounts committee  It's really up to the committee to determine how how long it wishes to examine a matter. I agree with Mr. Rochon. My role is to provide you with high-quality information so you can make decisions. The question whether a legislative change is necessary is really for Parliament to decide.

Public Accounts committee  It's very hard to compare our tax system to those of different parts of the country and other countries. Each one has a unique tax system. The estimates we made during the audit were really based on available public market information. They're just estimates, an attempt to show the scope of the situation.

Public Accounts committee  For those kinds of details, I'll turn to one of my colleagues, Philippe Le Goff. He can describe the methodology we use in comparing the Quebec data.

Public Accounts committee  As we noted in our report, the tax system has not really kept pace with the rapidly evolving digital economy. The policy change question should be put to the deputy minister, who is here today. We checked to see whether the existing system was neutral. We found that it was unfair in some respects and offered the agencies some options for improving it.
