Robert Sawyer has made a list of SF/F authors in or around Toronto (which qualifies as local, compared to the size of Canada). It’s not even a complete list, it’s only those that are at least moderately successful and well known. He counts to 24.
I guess if you don’t know about it already, you will miss it despite my posting this. Anyway, in case you are interested in taking a look at it after the meeting, here are some Iain [M] Banks related links.
And here he is, talking about his latest Culture novel, Matter. The guy you see in the background is Ken MacLeod (another scottish science fiction author).
