I will simply say that exemption powers are commonly used across various legislation, and I'm certainly not aware of any abuses of them. We've tried to look at that. They are narrowly constrained. One of the examples we thought of—and I'll just give it back as a possibility—is that if there were an earthquake in Vancouver, at the port of Vancouver, and tankers trying to land there couldn't land, there could be an option to send a tanker to Prince Rupert, perhaps, if the scale of an earthquake were such that both Seattle and Vancouver were affected. That is a possible emergency example that one could conceive of.
