As of this year, Ernest Hemingway is public domain in Canada, which may account for the Kobo cheapies.
Some of his titles are now in the MR Patricia Clark Memorial E-Book Library, for those who live in Life+50 countries.
BTW, if any of my fellow Canadians would like to keep Canada a Life+50 country, be sure to write your MP opposing the
proposed copyright extensions that are apparently up for discussion as part of the Trans-Pacific Partnership free trade talks. Project Gutenberg Canada has a bit on the top of their page about it. Our current Conservative government probably won't listen at all, but one should at least get one's word in before they start selling our heritage out to the highest corporate bidder.
