Just putting aside the question of whether it's legally possible, we talked about that before and I didn't have an answer for you. I guess the question is sort of on the practical feasibility.
I would make note that there already exists, and has for some time existed, reporting requirements in respect of income paid from Canadian entities to non-residents. That information is required to be provided on a form to the Canada Revenue Agency, and we have exchange of information already with many countries, including the United States. That information goes.
As a point of principle, if you're looking to require express notification in this case, I'm not certain why that wouldn't apply more broadly, and that I think could give rise to at least administrative and compliance costs.
