But if a Canadian author writes a good series not set in Canada, I can't ignore that (such as Alan Bradley). Does Peter Robinson count as a Canadian author?
To answer the question I started by looking up the submission criteria for the 2013 Arthur Ellis Awards sponsored by the Crime Writers of Canada. They state:
First publication (includes print, electronic/e-book, or self-published), whether in English or French, in the preceding year (2012) by a Canadian citizen regardless of place of residence, or by a writer, regardless of nationality, who has been granted Permanent Resident status in Canada.
Robinson was born in England and, after getting his B.A. in English Literature at Leeds University, he came to Canada in 1974 to study creative writing with Joyce Carol Oates at the University of Windsor. After earning an M.A. at Windsor and a Ph.D. at York University in Toronto he returned briefly to England. Not finding work he came back to Canada. He currently splits the year between Canada and England. I am not sure whether he is a Canadian citizen or has Permanent Resident status.
As Saskatchewan mysteries are at the core of my blog I looked up the Saskatchewan Book Awards for their criteria:
To be eligible for a Saskatchewan Book Award, authors must have resided in Saskatchewan for the twelve months immediately prior to the date of publication, or for four of the last five full calendar years.
Of the three most prominent Saskatchewan set mystery series two of the three authors, Gail Bowen and Anthony Bidulka, reside in Saskatchewan while the third, Nelson Brunanski lives in Victoria, British Columbia. (Nelson did grow up in Saskatchewan.) Of the trio only Gail and Anthony are eligible for the Saskatchewan Book Awards.
Personally, I have chosen to consider a Saskatchewan mystery any book set in Saskatchewan without regard to the residence or nationality of the author. That personal criteria means Prairie Hardball written by Toronto author, Alison Gordon, is a Saskatchewan mystery.
Perversely, I have set the standard for my page, Rest of Canada, to use the Arthur Ellis criteria for authors so that it does not matter whether their mysteries are set in Canada. While I prefer mysteries by Canadian authors to be set in Canada I decided I would include books set outside Canada on the principle authors retain their nationality no matter where they set their books.
I set up the sub-category of Rest of the World for those authors. Currently, Peter Robinson with a book in England and Linwood Barclay with books set in the United States fit within this group.
I consider setting your own arbitrary rules defining parts of your blog the right of a blogger.
