Quebec (Attorney General) v. Denis, 2026 SCC 25
The Supreme Court of Canada has released another important decision in the continuing constitutional debate over mandatory minimum sentences. In Quebec (Attorney General) v. Denis, 2026 SCC 25, a majority of the Court upheld the six-month mandatory minimum sentence imposed on individuals convicted of obtaining sexual services from a person under the age of eighteen for consideration.
Although the case does not directly concern wrongful convictions, it is highly significant for those who follow the development of constitutional sentencing principles and the scope of judicial discretion in criminal cases.
The Background
The case arose from a police sting operation targeting the sexual exploitation of children. Officers posted fictitious escort advertisements on websites known to advertise sexual services involving minors. Mario Denis responded to one of the advertisements and communicated with an undercover officer posing as the intermediary for a sixteen-year-old escort.
Mr. Denis ultimately attended a motel, paid money, and was arrested before any sexual activity occurred. He was subsequently convicted of obtaining sexual services from a person under eighteen years of age, contrary to section 286.1(2) of the Criminal Code.
The offence carries a mandatory minimum sentence of six months’ imprisonment.
The Constitutional Challenge
At sentencing, Mr. Denis argued that the mandatory minimum violated section 12 of the Canadian Charter of Rights and Freedoms, which protects against cruel and unusual punishment.
The Quebec Court of Appeal agreed with him. Although it found that six months’ imprisonment was a fit sentence in Mr. Denis’s own circumstances, it concluded that the mandatory minimum would be grossly disproportionate when applied to a reasonably foreseeable hypothetical offender—for example, an eighteen-year-old who offers money to an underage friend with whom he already has a personal relationship.
The Court of Appeal therefore declared the mandatory minimum sentence unconstitutional.
The Supreme Court’s Decision
By a 7-2 majority, the Supreme Court of Canada reversed the Quebec Court of Appeal and upheld the constitutionality of the mandatory minimum sentence.
The majority concluded that the hypothetical scenario relied upon by the Court of Appeal significantly understated the seriousness of the offence. Even in the proposed scenario, the conduct involved the sexual exploitation of a minor and constituted a grave criminal wrong.
The Court emphasized that Parliament is entitled to treat the commercial sexual exploitation of children as an exceptionally serious offence warranting denunciation and deterrence. The majority concluded that imposing a term of incarceration in such circumstances would not be so excessive as to outrage standards of decency or shock the conscience of Canadians.
Accordingly, the mandatory minimum sentence survived constitutional scrutiny.
The Dissent
Justices Karakatsanis and Moreau dissented.
The dissent took a very different view of the breadth of the offence. In their opinion, the provision captures a wide range of conduct and includes situations in which an offender’s moral blameworthiness may be relatively low. For those offenders, they concluded that six months’ imprisonment could amount to cruel and unusual punishment.
The dissent stated:
“When a proportionate sentence would not require actual imprisonment, sending a young first-time offender to prison for six months is a gross injustice.”
The dissent would therefore have struck down the mandatory minimum sentence entirely.
Why This Decision Matters
For criminal lawyers and advocates concerned with miscarriages of justice, the decision is significant for several reasons.
1. Continued Judicial Division on Mandatory Minimums
The Court remains deeply divided over how section 12 should be applied. Recent years have seen numerous mandatory minimum sentences struck down, including in cases involving firearms and drug offences. Denis demonstrates that the Court is not prepared to invalidate every mandatory minimum sentence and will continue to assess each provision on its own context and legislative purpose.
2. Emphasis on Parliament’s Role
The majority reaffirmed that Parliament has considerable latitude in identifying conduct that warrants strong denunciatory sentences. Courts will not lightly interfere with legislative choices, particularly where vulnerable victims—such as children—are involved.
3. The Continuing Debate Over “Reasonable Hypotheticals”
The case once again highlights the importance of the “reasonable hypothetical” doctrine in Charter litigation. Much of the disagreement between the majority and dissent centred on whether the proposed hypothetical offender was genuinely foreseeable and how blameworthy that offender would be.
4. Implications for Wrongful Conviction Advocacy
Mandatory minimum sentences have long been a concern for wrongful conviction advocates because they can create significant pressure on accused persons to plead guilty in order to avoid the risk of harsher punishment after trial.
Although the Court upheld the mandatory minimum in this case, the dissent’s reasons underscore the continuing constitutional concerns that arise whenever sentencing provisions remove judicial discretion and require incarceration in cases that may fall near the lower end of moral culpability.
Final Thoughts
The Supreme Court’s decision in Quebec (Attorney General) v. Denis reflects the difficult balance between protecting vulnerable children from sexual exploitation and ensuring that sentencing laws remain proportionate and constitutionally compliant.
For now, the six-month mandatory minimum sentence for obtaining sexual services from a person under eighteen remains valid law in Canada.
Yet the vigorous dissent demonstrates that the constitutional debate surrounding mandatory minimum sentences is far from over. As future cases continue to test the limits of section 12 of the Charter, the Court’s jurisprudence in this area remains very much a work in progress.
