I will start, and then Mr. McAuley may have more to add.
I will just make the point that with the tax information exchange agreements and with the revisions to our tax treaties—to make sure that all countries with which we have a relationship, and we are hoping to get a relationship with every country and subnational jurisdiction where they have separate responsibility for taxation—we're trying to get the template in place that allows our colleagues at the Canada Revenue Agency to get the information they require.
So the framework is supposed to be in place, and as I mentioned earlier, there is actually a peer review process to try to make sure not only that we sign these agreements but that the other countries we sign them with have the legal capacity and have, frankly, the willingness to, on the ground, give effect to change of information.
A lot of these, particularly the tax information exchange agreements, have been signed, and in some cases ratified, only very recently—they've come into effect only in the last year or so—so I think Canada Revenue Agency's ability to use these and to make requests under these exchange of information agreements is very nascent. That's how things are positioned.
