Niagara Falls is not owned by a single country; it is a shared natural wonder spanning the international border between Ontario, Canada, and New York, USA. The falls consist of three separate waterfalls: the American Falls and Bridal Veil Falls, which are entirely within U.S. territory, and the Horseshoe Falls, which straddles the border. According to the International Boundary Commission, approximately two-thirds of the Horseshoe Falls is in Canada, while one-third is in the U.S. Both nations manage the site through the Niagara Falls State Park (USA) and the Niagara Parks Commission (Canada), and they cooperate via the 1950 Niagara Treaty to regulate water diversion for hydroelectric power.
