Canadian mental health law has traditionally held many themes in common with the mental health law of other Commonwealth countries such as Britain, Australia, and New Zealand. Until recently, this body of law bore only a passing resemblance to the system of mental health law that has emerged in the United States.
The existence of an entrenched Bill of Rights in the United States has meant that many major issues relating to the rights of mental health patients have been dealt with as constitutional matters of great import. Consequently, the 1960s and 1970s witnessed the burgeoning of an exciting body of case law establishing a number of critical rights for a constituency that had hitherto been powerless and tragically neglected. While many of the rights established in the so-called landmark cases were subsequently limited in their scope or were just not affirmed by the appellate courts, the widespread use of constitutional challenges by mental health advocates wrought wholesale changes in both federal and state legislation and permanently altered the balance of power between mental health professionals and their patients.
