R v Oakes

Oakes establishes the analytical framework that governs every Charter limitation. After David Oakes was convicted of possession of narcotics, s.8 of the Narcotic Control Act reverse-onused him to prove the drugs were not for trafficking. The SCC struck the provision down and gave Canadian constitutional law its most-cited test.

Oakes was found with eight one-gram vials of hash oil and $619 in cash. Under s.8 of the Narcotic Control Act, once possession was proved, the accused had to prove on a balance of probabilities that he was not in possession for the purpose of trafficking. He challenged the reverse onus under s.11(d) of the Charter (presumption of innocence).

(1) Does s.8 of the Narcotic Control Act violate s.11(d) of the Charter? (2) If so, is it saved by s.1?

Yes to (1); No to (2). Section 8 is unconstitutional and of no force or effect.

A limit on a Charter right is justified under s.1 only if (a) the objective is pressing and substantial, and (b) the means are proportionate, which requires (i) a rational connection between the means and the objective, (ii) minimal impairment of the right, and (iii) overall proportionality between the salutary and deleterious effects of the measure.

Dickson CJ held that the presumption of innocence is a fundamental tenet of the criminal justice system. A reverse onus violates s.11(d) because it requires the accused to disprove an essential element on a balance of probabilities, leaving open the possibility of conviction despite reasonable doubt. The s.1 analysis requires the Crown to establish, on a balance of probabilities, that the limit is demonstrably justified in a free and democratic society. Combatting drug trafficking is pressing and substantial. But the rational connection failed: possession of a small quantity is not rationally connected to the inference of trafficking. The provision therefore could not be saved.

Oakes is the most-cited Charter case in Canadian history. Every s.1 analysis since 1986 begins by walking through the Oakes test. Its proportionality structure has influenced constitutional doctrine in South Africa, Israel, and the UK Human Rights Act jurisprudence.
