The Supreme Court of Canada has rendered a significant judgment that alters the landscape of sentencing for child pornography offences across the country1. In a decision released on October 31, 2025, the nation’s highest court declared that mandatory minimum sentences of one year in prison for the possession and accessing of child pornography are unconstitutional. The ruling in the case of Quebec (Attorney General) v. Senneville affirms that stripping judges of the discretion to impose sentences other than imprisonment in specific, lower-level cases violates the Canadian Charter of Rights and Freedoms. The decision restores the ability of trial judges to craft sentences that fit the specific circumstances of an offender, including the possibility of conditional discharges or community-based sentences for less severe conduct, while maintaining that serious offences will still attract significant prison time.
The case arrived at the Supreme Court following the convictions of two Quebec men, Louis-Pier Senneville and Mathieu Naud, in separate but legally connected proceedings. Louis-Pier Senneville, a former soldier who was twenty-eight years old at the time of his sentencing, had pleaded guilty to possession of and accessing child pornography. The investigation revealed that he had possessed 475 files, including 317 images, over a period of several months. Despite the serious nature of the material, the court noted several mitigating factors regarding his personal circumstances. Senneville had no prior criminal record, had cooperated fully with authorities, and a specialized assessment indicated he posed a low risk of reoffending. He had engaged in therapy and demonstrated sincere remorse for his actions.
In the parallel case, Mathieu Naud pleaded guilty to possession and distribution of child pornography. Naud, a man in his thirties with no prior criminal record, admitted to possessing over 500 images and nearly 300 videos. The sentencing judge in the lower court noted that Naud suffered from long-standing depression, isolation, and substance abuse issues. Like Senneville, Naud expressed significant shame and had undertaken therapy to address his behaviour. When these men appeared for sentencing, they faced a mandatory minimum penalty of one year in prison under the Criminal Code provisions enacted by Parliament in 2015. Both men challenged this requirement, arguing that a mandatory prison term would constitute cruel and unusual punishment in violation of Section 12 of the Charter.
The trial judge in the Court of Québec agreed with the offenders. He determined that sending Senneville and Naud to prison for a full year would be grossly disproportionate to their specific circumstances and culpability. Consequently, the judge declared the mandatory minimums unconstitutional as they applied to these two men and sentenced them to shorter, intermittent sentences or probation. The Quebec Court of Appeal subsequently upheld the finding of unconstitutionality but did so on broader grounds. The appellate court looked beyond the specific facts of Senneville and Naud and considered how the law might impact other reasonably foreseeable offenders. This set the stage for the Supreme Court of Canada to determine whether the law itself could stand.
Justice Moreau, writing for the majority of the Supreme Court, explained that the constitutional defect in the law lay in its broad reach. The offence of possessing child pornography covers a vast spectrum of conduct. On one end of the spectrum are sophisticated offenders who collect and organize thousands of images of extreme abuse. On the other end are individuals whose conduct, while criminal, is significantly less culpable. Because the mandatory minimum sentence applies to every offender prosecuted by indictment regardless of the specific facts, it casts a net that captures individuals for whom a year in prison would be abhorrently excessive.
To determine if the law violated the Charter, the Court employed a legal test known as the “reasonable hypothetical.” This analysis requires the court to consider not just the offenders currently before them, but whether the law would result in cruel and unusual punishment in other realistic scenarios. The scenario that weighed heavily in the Court’s decision involved a hypothetical eighteen-year-old with no criminal record. In this scenario, the young adult receives a “sext” or intimate image from a friend comprising a photo of the friend’s seventeen-year-old girlfriend. The eighteen-year-old does not distribute the image but keeps it on his phone for a brief period. Under the definition of the law, this constitutes possession of child pornography.
The majority reasoned that under the mandatory minimum sentencing regime, a judge would have no choice but to send this hypothetical eighteen-year-old to prison for one year. Justice Moreau concluded that such a result would be grossly disproportionate. A fit sentence for a young, first-time offender in those specific circumstances might be a conditional discharge or probation, measures that would hold the offender accountable without the lasting stigma and damage of incarceration. Because the mandatory minimum removed the flexibility to impose a fit sentence in such a low-level case, the law was found to violate the protection against cruel and unusual punishment.
The Court emphasized that striking down the mandatory minimum does not mean child pornography is viewed as a less serious crime. The judgment reiterated the profound harm that sexual violence and exploitation cause to children and society. The decision explicitly stated that the objectives of denunciation and deterrence remain primary considerations in sentencing for these offences. However, the rigid mechanism of a mandatory minimum sentence was deemed too blunt an instrument. It prevented judges from distinguishing between a predatory collector of abuse materials and a young adult making a foolish but isolated mistake with digital media.
The legislative history of these provisions shows a trend by Parliament over the last two decades to increase penalties for sexual offences against children. In 2005, the minimum sentence was set at forty-five days. This was increased to six months in 2012, and then to one year in 2015 under the Tougher Penalties for Child Predators Act. The Supreme Court acknowledged Parliament’s intention to punish these crimes severely. Nevertheless, the Court held that Parliament cannot enact sentences that result in grossly disproportionate punishment for reasonable foreseeable offenders. The hybrid nature of the offence also played a role in the decision. Since prosecutors can choose to proceed by summary conviction (which carries a lower minimum) or by indictment (which carried the one-year minimum), the severity of the punishment could arbitrarily depend on a procedural election by the Crown rather than the gravity of the accused’s conduct.
The decision was not unanimous. Chief Justice Wagner and Justice Côté penned a strong dissenting opinion, joined by two other justices. The dissenting judges argued that the appeal should have been allowed and the mandatory minimums upheld. They fundamentally disagreed with the majority’s use of the hypothetical scenario involving the eighteen-year-old. In their view, this scenario was too remote and far-fetched to serve as the basis for striking down a law meant to protect children. The dissent argued that the scenario did not have a sufficient connection to the actual cases of Senneville and Naud, who possessed hundreds of images.
The dissenting justices emphasized that the justice system must reflect society’s deep indignation toward the exploitation of children. They argued that the protection of children is a paramount value and that the mandatory minimum sentences were a valid expression of Parliament’s will to deter such crimes. They expressed concern that the majority’s approach expanded the use of hypothetical scenarios too far, potentially destabilizing the presumption that laws enacted by Parliament are constitutional. For the dissent, the one-year minimum was not grossly disproportionate given the inherent harm in possessing any material depicting the sexual abuse of a child.
Despite the strong dissent, the majority ruling stands as the law of the land. The immediate effect of the decision is that sentencing judges across Canada now have full discretion when sentencing offenders for possession and accessing child pornography. They are no longer bound by the one-year floor. This does not imply that sentences will automatically be lenient. The Court was clear that imprisonment remains a likely and appropriate sentence for many, if not most, offenders who commit these crimes. The ruling simply ensures that in exceptional or lower-end cases, judges are not forced to impose a prison term that would shock the conscience of the community.
The decision also highlights the evolving challenges of applying criminal law in the digital age. The Court recognized that the ubiquity of digital communication and the ease with which images can be shared or saved creates a wide variety of conduct that falls under the technical definition of child pornography. By removing the mandatory minimum, the Court has ensured that the justice system can differentiate between different types of conduct and distinct levels of moral blameworthiness.
Moving forward, sentencing hearings for these offences will likely involve more detailed arguments regarding the specific circumstances of the offender and the offence. Defence lawyers will be able to argue for community-based sentences in appropriate cases without facing a statutory bar. Meanwhile, Crown prosecutors will continue to advocate for stiff penalties based on the principles of denunciation and deterrence, which the Supreme Court affirmed are still the primary objectives in sentencing for sexual offences against children. The declaration of invalidity takes immediate effect, meaning it applies to all current and future cases before the courts.
