How do I protect my idea from theft?
In Canada, you automatically hold the copyright to any original work you produce. You can’t copyright an idea or a title; only the written expression of your idea. Someone else might also write a book on jungle cats from outer space but it’s not a problem unless they use your words.
Usually copyright is registered at the time of publication. It is not necessary for you to register before that but although it is not necessary, you can pay to register your copyright with The Copyright Office. For more information check http://strategis.ic.gc.ca/sc_mrksv/cipo/cp/cp_main-e.html
