Binational Legal Assessment Dossier
UNILATERAL EXECUTIVE ACTION: NO INTERNATIONAL JURISDICTION
Because Lake Ontario contains 52% Canadian sovereign territory, unilateral US renaming has zero binding effect on Canadian waters, Canadian Hydrographic Service charts, or international maritime law. Under 43 U.S.C. § 364, the US BGN could adopt the name solely for domestic federal agencies (NOAA/USGS), creating a confusing dual-name nautical chart split at the international boundary line.
