Spring 1940 was the first occasion the American Association of Variable Star Observers held their meetings outside of the United States. The meetings were held at the University of Toronto, and included a paper session at the David Dunlap Observatory and a garden party (by special invitation) at Don Alda Farm hosted by Mrs. Dunlap. The meetings concluded with a formal dinner in the Great Hall of Hart House jointly hosted by the AAVSO and the RASC.
