There have been for some. I can't speak for eastern Canada. Here in the western part of the world, I know they're working on some....
The Columbia River has been a point of contention. We have not seen it yet in the International Souris River Board. The Souris River is unique in the sense that it starts in Saskatchewan, goes into North Dakota and comes back into Manitoba. It crosses that international boundary twice.
Under the guidance of the International Joint Commission, which is long-standing, they work on water apportionment based on natural flows, as well as water quality. Certainly, the Red River in Manitoba flows from North Dakota and Minnesota into Manitoba.
As we get into various situations, we are probably going to see concerns raised with regard to water flow across international boundaries. I think it's imperative that the new Canada water agency does not work in a silo but with other organizations, such as the International Joint Commission, which is responsible for those waters along the Canada-U.S. boundary, including the Great Lakes.
