Canada currently has the fairest and most comprehensive charter of rights and freedoms in the world. It is the most important set of laws in Canada, as it overrides all other Canadian laws, including all municipal and provincial statutes. And, the charter was intentionally designed to be difficult to change. With this charter, truthful, proven and demonstrable harm just occur before punishment may be legally imposed (demonstrable justification). This is similar to the charter's guaranteed right of liberty (doing non-harmful actions). A law that has the potential of convicting a person who has not really done anything wrong offends the principles of fundamental justice; and such a law violates a person's right to liberty, under section 7 of the Canadian Charter of Rights and Freedoms. Each person is the proper guardian of their own health, whether bodily, or mental and spiritual. The right most valued by civilized man is the right to be let alone. Specific charter rights also apply to arrest, detention, and bail requirements.
