For the ninth time in its history, Parliament will hear from the President of the United States on Wednesday, when Barack Obama addresses a joint session of the House of Commons and Senate.

Beginning with Harry Truman in 1947, six presidents have addressed Parliament: Ronald Reagan and Dwight Eisenhower did so twice.

Each speech has, of course, included a salute to the relationship between Canada and the United States, but with unique reflections on the issues of the day and the state of the world.
