The Annual Day of Aerophilately is a joint gathering of the Canadian Aerophilatelic Society and the BNAPS Air Mail Study Group, held each fall at the Vincent Graves Greene Philatelic Foundation, 10 Summerhill Avenue, Toronto. It brings together collectors and researchers interested in aerophilately and airmail postal history. The program typically features two feature talks by CAS and BNAPS members followed by lunch on nearby Yonge Street and an afternoon of show-and-tell, discussion, and trading. The VGGF library opens from 10:00 a.m. for research before and during the meeting.
