Transboundary Waters
On this page you will find a listing of all the transboundary (those which cross) and boundary (those that form) waters along the Canada-U.S. border with a summary of IJC activities.
The following maps depict the key transboundary basins shared between Canada and the US. Wherever applicable, links to webpages of active IJC boards working in these watersheds are also included. Note that the Health Professionals Advisory Board does not appear under any watersheds because its work is not tied to any one specific watershed.
