Here’s what you need to know:
In Canada book titles are not copyrightable. An author’s main concern should be confusion with other titles. You don’t want your marketing efforts to send readers to the wrong book. It’s advisable to search Google for your title to see the competition you’re up against for search engine optimization, but don’t let that stop you from using a title you really want to.
Hope that helps.
