2007, updates of satellite photos led Canada to recognize the international border as crossing through the middle of Hans Island, not to the east of the island as previously claimed. Hans Island – (1933–present) Northwest Passage The Canadian government considers the Northwestern Passages part of Canadian Internal Waters, but the United States and various European countries maintain they are an international strait or transit passage, allowing free and unencumbered passage. Areas disputed by the United States Although Canada and the United States share the longest non-militarized border between two countries, there is a long history of disputes about the border's demarcation. Proposed provinces and territories Since Confederation in 1867, there have been several proposals for new Canadian provinces and territories. The Constitution of Canada requires an amendment for the creation of a new province but the creation of a new territory requires only an act of Parliament; therefore, it is easier legislatively to create a territory than a province.
