Just so I understand the question, is it about the currently enacted laws of Canada, as well as our treaty network? There are anti-abuse rules in the Income Tax Act—there's section 245 of the act dealing with the general anti-avoidance rule—that were introduced a few years ago, which were intended to prevent the misuse or abuse through abusive tax avoidance transactions to obtain their tax benefits through treaties. Recent case law has been developed along those lines. It's not to say there's nothing in our current tax law that could address this type of planning, but the multilateral instrument is rather a coordinated international effort to address this sort of tax planning and to do so, as I said, in a coordinated and more effective way.
