I'll just make a brief comment, Mr. Chair, before turning it over to Wayne.
I think a number of the observations you made relate probably more to tax policy than to tax administration. That being said, in all fairness, the agency does take this issue very seriously. The government has made significant investments over time. It's certainly, as John said, one of our top four priorities that we focus on.
I would note that in the last Auditor General's report, which perhaps doesn't happen all that frequently, we really got good marks in terms of the efforts we were making within our responsibility as an administrator. So we are doing our best, but it is a difficult and, I would note too, long-term challenge.
It was interesting. We were looking at the issue of exchange of information agreements, and someone noted that the U.S. has 20 information exchange agreements, and we're still working on our first. We then pointed out to the individual that the United States started in 1983 and didn't sign the first agreements until, I think, the early 2000s, if I remember.
