That's really by its nature. The multilateral instrument is really just meant to be an effective way of making uniform changes to all tax treaties around the world. That's the goal of it. As a result, it's limited in terms of what you can put into it with regard to things that Canada as a country would agree, in all of our treaties or most of our treaties, to give up.
It doesn't get into that bilateral negotiation of “I'll give you something if you give me something.” As a result, particularly on the anti-avoidance side, it has to be broad and ambiguous to give tax authorities around the world the ability to apply it in the way they would want to, even though that's going to create a lot of uncertainty for taxpayers.
