Freedom to Read's "Challenged Books in Canada"
"This selective list provides information on more than 100 books that have been challenged in the past 21 years. Each challenge sought to limit public access to the books in schools, libraries, or bookstores. Some challenges were upheld; others were rejected.
Because some challenges are dismissed, the books remain on library shelves or curriculum lists. We think it worthwhile to include such instances because the effect of a controversy over print material can spread, even though the would-be book-banners lose. A book with a controversial reputation tends to be quietly dropped from reading lists and curricula. This interference can be most insidious—quiet acquiescence to the kind of scare tactics that would-be censors know how to employ.
Because organizations and community groups that ask for book and magazine bans generally want to avoid public controversies, it is often difficult to discover why challenges are launched or what becomes of them."
Note: This list is updated by Freedom to Read periodically, so will be changed here, too. It doesn’t include the periodicals they list, or books written in French.
