The Friends of the Merril are having a Flea Market on Saturday September 8th, from 10-4, at the Toronto Reference Library (just north of Bloor on Yonge). Second-hand, collectible, or one-of-a-kind: all sorts of SF and Anime merchandise will be available.
The Merril Collection of Science Fiction, Speculation and Fantasy is a Huge collection of over 63,000 items(!!!) started when pioneering science fiction author/editor/goddess Judith Merril donated her personal collection to the Toronto Public Library.
Note: the collection is housed on College Street near Spadina; not near Yonge and Bloor, and the flea market is not at the collection.
