Thank you very much for the question, Mr. Chair.
From an international treaty perspective, as I mentioned in my opening remarks and in responding to a few of the questions I've answered, we have negotiated some flexibility in our trade agreements that would allow the Government of Canada to take some decisions with respect to offering preferential access to Canadian investors and investments. In terms of what those barriers are, I can only speak to, from my perspective, the international investment treaties that we have negotiated. As I mentioned, we have actually negotiated some policy flexibility in those areas.
