In 1939 the King and Queen of English visited North America from May 17 through June 17. During that time they traveled to Canada, the United States and Newfoundland, which was then not yet part of Canada.

The main part of the royal couple's itinerary was through out Canada, but, for a few days, King George VI and Queen Elizabeth visited the United States. A special post office was opened on the Royal Train.

There were also special machine and hand cancels used on mail sent from the Royal Train RPO.
