I've heard from a few people who have had some difficulty getting their hands on a copy of The Gospel According to Science Fiction in Canada. The book is not in stock at Amazon.ca. However, it is in stock at chapters.indigo.ca, so you don't have to deal with a backorder wait. The book is still in print, so there's no need to fear your order getting canceled if it's backordered. And if all else fails, there's always eBay Canada!
