The Ontario Science Fiction Club, a club located in Toronto, Canada which published the clubzines Synapse, OSFIComm, Ishue, and Nor. The club was founded ca. 1967; it was wound up ca. 1984. It had at least two branches, in Toronto and in Ottawa. It also was involved in KingCon.

It was one of the sponsors of the Fan Fair and sponsored the Toronto in 73 Worldcon bid and then the subsequent Torcon II. Running the Worldcon sapped OSFiC strength and nearly killed the club.

This is a club page. Please extend it by adding information about when and where the club met, how long it was active, notable accomplishments, well-known members, club fanzines, any conventions it ran, external links to the club's website, other club pages, etc.

When there's a floreat (Fl.), this indicates the time or times for which we have found evidence that the club existed. This is probably not going to represent the club's full lifetime, so please update it if you can!
