Unfortunately, I think the short answer is no, for two reasons. One reason is that so much of our transboundary water relationship is governed by the International Boundary Waters Treaty, which is unique. It is unique to Canada and the United States. It reflects a long history of cooperation. It reflects certain unique legal principles that work for us, but probably wouldn't work in a different geopolitical context.
The other reason is that there are lots of other states that have gone further in terms of interjurisdictional management, which tend to follow more in terms of customary international law in terms of how you share water basins. For example, I would think they'd be more inclined to look at something like the Murray-Darling, which is not an international compact in Australia, but it's an interstate arrangement, with the Commonwealth taking the lead.
That seems to me to have gone further than anything I can think of in Canada. We do have some interprovincial compacts in Canada as well, but not as sophisticated as the Murray-Darling. Where that may change is actually on the Mackenzie, where there is a series of bilateral negotiations going on among the jurisdictions in the Mackenzie basin. Perhaps there we'll get some leadership, but I think our circumstances in Canada are so unique that it's unlikely we would get that.
