Explanation:

After the War of 1812, the United States of America and Great Britain had series of improved relationships with one another. These mutual relationships gave rise to the signing of the 1817 Rush-Bagot Pact and Convention of 1818 which played a significant role in the resolution of longstanding boundary disputes with respect to the 1783 Treaty of Paris.

Under President James Monroe, the 49th parallel was set as the boundary between the United States and Canada by Convention of 1818, which was signed on the 20th of October, 1818 in London, United Kingdom.
