The Unbroken Line --
"This is a historical survey of the office of the Canadian governor general, from its inception through the inauguration of Edward Schreyer to office. Drawing from archival photos and using live-action film footage, The Unbroken Line gives us a look at some of the governors general (and their families) who have contributed to the Canadian political system."
