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. 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.  What is the Rush Bagot agreement? The exchange of ticketsThe Rush Bagot Treaty was extremely unusual, as it was based on an exchange of notes (letters) between Richard Rush and Sir Charles Bagot. The terms were proposed to Richard Rush by President Monroe in a letter of August 2, 1816. The method used to reach the agreement between the governments of the United States and the United Kingdom was the diplomatic instrument known as the «note exchange.» A series of notes between Rush and Bagot and they reached an agreement.
In 1818, the U.S. Senate approved the notes and gave them the authority of a treaty. The simple exchange of notes between the two diplomats thus became the Rush-Bagot treaty. 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. Mr. Bagot met informally with Foreign Affairs Minister James Monroe and finally reached an agreement with his successor, Current Minister Richard Rush.
