The Facts: David Oakes and the Reverse Onus
In 1981, David Edwin Oakes was sitting in his car near a tavern in London, Ontario, when police found vials of cannabis resin, hash oil, and several hundred dollars in cash. Oakes said the drugs were for personal use. But under the Narcotic Control Act, simply possessing drugs triggered a presumption of trafficking — a reverse onus that forced Oakes to prove his innocence or face life imprisonment.

“I don’t think in that moment in 1981 he could have imagined that his case would end up becoming a seminal and definitive leading case in Canadian constitutional law,” Professor Bakan observes.

The Constitutional Question
Can the government override the presumption of innocence in the name of fighting drug trafficking? The case pitted “an ancient and hallowed individual right, the presumption of innocence, against a powerful collective interest, which was stopping illicit drug trafficking.”

Before Oakes: Ad Hoc Reasoning
Prior to Oakes, the Court had no criteria for determining whether a limit on rights was “reasonable and demonstrably justified in a free and democratic society.” Professor Bakan explains: “The Court kind of went on a hunch — well, yeah, it seems reasonable, or it doesn’t. But there were no criteria. This was becoming frustrating for Chief Justice Dickson.”

The Birth of the Oakes Test
Chief Justice Dickson saw in this case “an opportunity to create principles for applying Section 1.” The Oakes test establishes that a law limiting a Charter right can be upheld if:

1. Pressing and substantial purpose — The law’s objective must be sufficiently important
2. Rational connection — The means must be rationally connected to the objective
3. Minimal impairment — The law must impair the right as little as possible
4. Proportionality of effects — The positive effects must outweigh the negative effects on rights

The Decision in Oakes
The Court found that while stopping drug trafficking was a pressing and substantial purpose, the reverse onus clause failed at the rational connection stage. “You would be catching a lot of people who were not drug traffickers, and catching people who aren’t drug traffickers doesn’t serve the purpose of catching drug traffickers.”

Clerking During History
Professor Bakan describes his experience: “Chief Justice Dickson was writing what his biographers Kent Roach and Robert Sharp described as five of the most important pages ever written in Canadian constitutional law. I think the Chief Justice had a sense that he was writing five of the most important pages ever written in Canadian constitutional law.”

Section 1: A Unique Compromise
Professor Moore explains that Section 1 was part of a political compromise. Many feared the Charter would give too much power to judges. “That concern was particularly sharp in Quebec,” Professor Bakan notes, “which didn’t sign on to the Charter because it was seen as a federal instrument with a federal Court that could unduly dictate law and policy.”

Balancing vs. Principled Tests
Constitutional scholars debated two approaches: a “balancing” approach trusting judges to weigh competing interests, or a “principled” approach with rules binding judges to reach right results. “The Oakes test basically incorporates both,” Professor Bakan explains. The first three stages use principled measurement; the fourth opens up balancing.

The Advantage of Oakes: Forcing Values Into the Open
“The advantage of the Oakes test is you really have to run this gauntlet of principled and rational tests that force you to engage in a very reasoned approach,” Professor Bakan argues. “One of the problems with balancing tests is there’s always a previous decision before the balance is done about what is being balanced against what… The values are kind of hidden. The Oakes test forces them into the open.”

Evolution: Minimal Impairment Does the Work
In practice, Professor Moore notes, “the minimal impairment step of the test is the one that does much of the work.” The Court quickly relaxed the strict standard in Edwards Books (1986), the same year as Oakes. “There’s been inconsistency since then — if it helps a particular conclusion to use the stricter version, we see that one used.”

The Keegstra Example: Values Matter
Professor Bakan points to R. v. Keegstra (the hate speech case) as illustrating that values ultimately drive decisions: “There are two incredibly persuasive, elegantly reasoned judgments going in totally contradictory directions” — Chief Justice Dickson’s majority and Justice McLachlin’s dissent — reflecting different presumptions about freedom of expression and criminal law.

Global Influence
The Oakes test has been “looked to as a model around the world,” Professor Moore notes. Proportionality analysis originated in German law regarding police use of force, spread to the European Court of Human Rights, and the Oakes test became another influential model internationally.

A Constitutional Definition of Democracy
Professor Bakan emphasizes an often-overlooked aspect of Oakes: Chief Justice Dickson’s definition of “a free and democratic society” as including:

• Respect for the inherent dignity of the human person
• Commitment to social justice and equality
• Accommodation of a wide variety of beliefs
• Respect for cultural and group identity
• Faith in social and political institutions that enhance participation

“A very different understanding of democracy than you might get in a lot of other places, including the United States,” Professor Bakan observes. “We have in Canada a definition of democracy that is constitutionally entrenched.”

The Future: Section 33 and Populism
Professor Bakan raises concerns about the Charter’s future: “With governments increasingly moving in a populist right-wing direction and becoming more inclined to invoke Section 33 [the notwithstanding clause], one can imagine a future where the Charter becomes a less significant protector of rights.”

Should Canadians Be Proud?
“Absolutely,” Professor Moore affirms. “Opinion surveys have identified the Charter as one of the things that Canadians are proud of and associate with their national identity. And the Oakes test is a big part of how the Charter works in practice… It has stood the test of time. It’s surpassed the test of geographic spreading to other jurisdictions around the world.”
