Following their discussions, the two heads of state and government concluded the Ogdensburg agreement. The agreement, signed on August 17, 1940, called for the creation of a joint U.S.-Canadian body to coordinate the defence of North America. The Ogdensburg meetings also resulted in negotiations between the British and American governments, which would be extremely useful to the Allied war effort. Finally, the U.S. Navy agreed to send 50 U.S. destroyers to the Royal Navy and the Royal Canadian Navy in exchange for leases at several British bases in North America. This agreement was reached in the Destroyers for Base Agreement of September 5, 1940. The Ogdensburg Agreement was an agreement between Canadian Prime Minister William Lyon Mackenzie King and U.S. President Franklin D. Roosevelt on August 17, 1940 in Heuvelton, near Ogdensburg, New York.  He outlined a permanent plan for mutual foreign defence between the United States and Canada and created the Permanent Defence Council. The Ogdensburg Agreement of August 18, 1940 was developed to create a framework for closer continental defence cooperation in the face of the Second World War between Canada and the United States.
Recalling the close ties between Prime Minister Mackenzie King and President Roosevelt, the agreement was reached in a “most informal character, in which the President and Prime Minister ins. Mr. Roosevelt`s private car was assigned, while it was within sight of a siding in the village of Heuvelton, New York, reported the New York Times 1940 (Hurd). Ogdensburg`s brief statement focused on the creation of the Standing Committee on Common Defence (PJBD), which included Canadian and American military and civilian researchers. The PJBD should serve as a communication forum between Canada and the United States, as well as a tool for establishing assessments of the “northern half of the Western Hemisphere`s defence.” It is important to note that the creation of the Board of Directors was deliberately designed to survive the war (Granatstein, 9f). Most Canadians supported the agreement, soon to be known as the Ogdensburg Agreement, as it was deemed necessary not only for security reasons, but also to improve relations with the United States (it was also hoped that the agreement would help wage war on the United States). However, some Canadians, particularly former Conservative Prime Minister Arthur Meighen, were furious – they argued that by signing this agreement, Canada was not only abandoning Britain, but was in fact under the control of the United States. British Prime Minister Winston Churchill was also upset and said that “all these transactions [at the end of the war] are judged in a different mindset than the prevailing one, while the subject is still pending.” King`s government has acknowledged these concerns; Canadian negotiators have firmly refused to give the United States control of the Canadian Armed Forces and have rejected proposals to integrate much of the country`s defence into the defence commandos of Northeast and Northwest Washington.
