Mr. Chair, I can attempt to answer that question. I'm not sure if it will be a satisfying answer. We're here from the tax policy branch at the Department of Finance, and I think the issue at hand here is that it's not so much a tax as it is a total ban or prohibition. A tax is something used to raise revenues. You would use something else to effect that ban or prohibition.
So I don't think I could speak to it. I'm not qualified to speak to what the international implications of that would be.
That's all, Mr. Chair.
