Which 1846 treaty set the 49th parallel as Canada-US border west of the Great Lakes?

Question: Which 1846 treaty set the 49th parallel as Canada-US border west of the Great Lakes?

Answer options: ✅ Oregon Treaty

• Webster-Ashburton
• Treaty of Ghent
• Jay Treaty

Correct answer: Oregon Treaty

Explanation: The Oregon Treaty of 1846 is correct because it established the 49th parallel as the boundary between British North America and the United States from the Rocky Mountains to the Pacific. In contrast, the Treaty of Ghent ended the War of 1812, the Webster-Ashburton Treaty settled the Maine-New Brunswick boundary, and the Jay Treaty addressed post-Revolutionary War trade and border disputes. This historical timeline demonstrates how Canada's borders were peacefully negotiated. On the citizenship exam, candidates should expect questions regarding key treaties and historical milestones that defined Canada's geographical sovereignty and shaped the country's peaceful relationship with its southern neighbour.
