Freedom of expression is a fundamental right protected by the Charter of Rights and Freedoms, which is part of the Constitution of Canada. But even that right has limits. Peacefully picketing an abortion clinic, so long as patients can come and go, is a protected right, but shouting "Fire!" in a crowded theatre to cause a stampede is a criminal offence. This book explains how our courts interpret the term "freedom of speech" and explains the difference between expressing one's views freely and infringing upon the rights of others.
