Interestingly, internationally, fees are not charged for transiting through another nation's waters. The right of innocent passage in international law allows, with some restrictions, vessels to transit through other countries' waters.
Fees tend to be applied when you enter a port or require a service from whatever country. At this point, ships that are transiting the Northwest Passage aren't calling at a Canadian port. They're simply passing through our waters. As a result, based on the current international framework, there is not an opportunity to charge for things. In the future that may change as ports become developed in the north, but at this point there is no fee.
Commissioner, do you want to speak to what happens in the case of your having to enter into things?
