Section 1 of the Canadian Charter of Rights and Freedoms

Section 1 of the Canadian Charter of Rights and Freedoms is the section that confirms that the rights listed in the Charter are guaranteed. The section is also known as the reasonable limits clause or limitations clause, as it legally allows the government to limit an individual's Charter rights. This limitation on rights has been used in the last twenty years to prevent a variety of objectionable conduct such as hate speech (e.g., in R. v. Keegstra) and obscenity (e.g., in R. v. Butler).

When the government has limited an individual's right, there is an onus upon the Crown to show, on the balance of probabilities, firstly, that the limitation was prescribed by law namely, that the law is attuned to the values of accessibility and intelligibility; and secondly, that it is justified in a free and democratic society, which means that it must have a justifiable purpose and must be proportional.

Under the heading of "Guarantee of Rights and Freedoms", the section states:

The inquiry into whether the limitation was "prescribed by law" concerns the situation where the limitation was the result of some conduct of a government or its agents and whether the conduct was authorized by accessible and intelligible law. The Court articulated when the authorization would fail for being too vague as "where there is no intelligible standard and where the legislature has given a plenary discretion to do whatever seems best in a wide set of circumstances".

Where there is no lawful basis for the conduct the limitation will certainly fail. In Little Sisters Book and Art Emporium v. Canada, the Supreme Court found that the conduct of a border official in singling out homosexual from heterosexual reading materials was not authorized by any law. Likewise, police conduct that was not exercised under lawful authority will fail at this stage.

The primary test to determine if the purpose is demonstrably justifiable in a free and democratic society is known as the Oakes test, which takes its name from the essential case R. v. Oakes [1986] 1 S.C.R. 103 which was written by Chief Justice Dickson. The test is applied once the claimant has proven that one of the provisions of the Charter has been violated. The onus is on the Crown to pass the Oakes test.
