Freedom of expression in Canada
Freedom of expression in Canada is protected as a "fundamental freedom" by Section 2 of the Canadian Charter of Rights and Freedoms (enacted 1982); however, in practice the Charter permits the government to enforce "reasonable" limits censoring speech. Hate speech, obscenity, and defamation are common categories of restricted speech in Canada.
