I downloaded several PDF files of text books from Library Genesis, and had them printed and bound for better reading experience. Now I've finished reading them, and plan to sell them on websites like Kijiji. Is that legal in Canada?
You infringe copyright1 when you download a textbook, print a textbook, or sell your personally printed copy of a textbook.2 Each of those steps on its own is infringement.
1. Copyright Act Sections 3(1), 27(1)
2. Unless the textbooks are in the public domain (i.e. copyrights have expired) or if the textbooks are licensed to allow your reproduction and sale. Most textbooks on Library Genesis are neither in the public domain nor properly licensed for that purpose.
