Concerning this lunacy of a border tax, when I was in Washington a few weeks ago, I'd sit with a congressman and say, “Look, when I'm in my living room in Toronto, I'm consuming electricity that was produced in Cleveland, in New York, in Quebec, or in Ontario. How are you going to tax that?” Not one of them had any kind of coherent answer. My suspicion is that when a lot of this nonsense about a border tax is actually addressed, it will simply be seen as that. It's virtually an impossible thing to do.
