I brought a map, and I don't know if you've seen it, but if you look at the Arctic on the eastern side, looking into Hudson Bay, that's probably the best place to come in because that's an open-water port for at least three months of the year. That being said, there's also infrastructure in Hudson Bay to do some screening.
So yes, we could have increased access to the north. There is a possibility you could get some smuggling, but I still think there are easier ways to do it south of 66° north than going through the trouble of doing it north of that.
