Although the agreements did not fully resolve border disputes and trade agreements, the Rush Bagot Agreement and the 1818 Agreement marked an important turning point in Anglo-American and American-Canadian relations. The rush bagot pact was an agreement between the United States and Great Britain to eliminate their fleets from the Great Lakes, with the exception of small patrol vessels. The 1818 convention established the border between the territory of Missouri in the United States and British North America (later Canada) at the forty-ninth parallel. Both agreements reflected the easing of diplomatic tensions that led to the War of 1812 and marked the beginning of Anglo-American cooperation. The Rush Bagot Treaty, also known as Rush Bagot Disarmament, was an agreement between the United Kingdom and the United States. This agreement demilitarized the America-Canada border and established the largest east-west border and demilitarized zone in the world. It all started with the exchange of letters between the current US Secretary of State, Richard Rush, and the British Minister in Washington Sir Charles Bagot. The letters were signed on April 27 and 28, 1817. After the terms of Bagot and Rush`s letters were agreed upon, the United States and the United Kingdom informally recognized the agreement. April 1818 proposed by U.S. Secretary of State James Monroe to British Foreign Minister Lord Castlereagh, then confirmed by Canada. The Rush Bagot Agreement of 1817 called for a massive demilitarization of lakes along the international border, where many British naval gatherings remained. The treaty stipulated that the United States and the United Kingdom could have only one military vessel and one cannon on both Lake Ontario and Lake Champlain.
On the Great Lakes, the United States and British North America were able to hold two naval vessels. The importance of the Rush Bagot Agreement was to lay the groundwork for a secure and demilitarized border between the United States and British North America. Finally, the agreement culminated in 1871 with the Washington Treaty, which concluded disarmament. Although the treaty was a challenge during the First World War, its conditions were not changed. Similar problems arose before the Second World War, but Foreign Minister Cordell Hull wanted to maintain the agreement because of its historical importance. In 1939 and 1940, Canada and the United States agreed to interpret the treaty so that weapons would be installed in the Great Lakes, but would not be passable until the ships had left the lakes. In 1942, the United States, which had gone to war and allied with Canada, successfully proposed to install and test weapons in the lakes until the end of the war. In 1946, following discussions in the Permanent Joint Defence Council, Canada also proposed to interpret the agreement to allow the use of ships for training purposes when each country informs the other country.  An Ontario Heritage Trust plaque in Kingston, Ontario, recognizes the Rush Bagot Agreement (44-13`48`N 76-27-59`W / 44.22989 N 76.466292-W / 44.229894; -76.4662922). A commemorative plaque is also located on the former site of the British envoy in Washington, D.C., D.C. (38-54`13.N 77-3`8.4`W / 38.903806 N 77.05233-W / 38.903806; -77.052333), where the agreement was negotiated.
A monument is also located on the site of the Old Fort Niagara (43-15`N 79-03`49`W / 43.263347 N 79.063719 W / 43.263347; -79.063719), reliefs of Rush and Bagot, as well as the words of the treaty.  Mr. Bagot met informally with Foreign Affairs Minister James Monroe and finally reached an agreement with his successor, Current Minister Richard Rush.
