Ontario’s Sex Offender Registry Law Found Unconstitutional

A Hamilton judge has struck down two pillars of Christopher’s Law, ruling that mandatory registration and lifetime reporting violate the Charter — and that the Supreme Court’s landmark Ndhlovu decision compels the same result at the provincial level.

In a closely watched constitutional challenge, Justice Davin M.K. Garg of the Ontario Court of Justice has declared that two central provisions of Christopher’s Law (Sex Offender Registry), 2000 violate s. 7 of the Canadian Charter of Rights and Freedoms and are not saved by s. 1. The ruling stays the charge against applicant Michael Roberts, who deliberately failed to report to the provincial registry after thirteen years of compliance — a calculated act of civil disobedience designed to force the constitutional question before the courts.

Background: A Registry Born from Tragedy

Christopher’s Law was enacted in 2000 in direct response to a harrowing case: in 1988, eleven-year-old Christopher Stephenson was abducted, sexually assaulted, and murdered by a convicted sex offender who had been released after serving five years for a prior offence against another child. A 1993 coroner’s inquest recommended a centralized police registry as one of 77 measures to prevent similar tragedies. The Ontario legislature acted on that recommendation, and the provincial registry came into force in April 2001.

The regime requires sex offenders to register detailed personal information — including addresses, photographs, vehicle details, employer information, and physical descriptors — and to report annually to police. Offenders convicted of a single offence with a maximum sentence not exceeding ten years must report for ten years. Those convicted of multiple offences, or of more serious single offences, face a lifetime reporting obligation.

The Applicant’s Strategy

Michael Roberts was convicted in 2010 of eight counts of sexual assault (the Crown proceeded summarily), receiving four months of concurrent custody. He had been reporting annually ever since — until June 2024, when he intentionally skipped his required check-in. He was charged that September.

His goal was never to escape accountability. Roberts had already fulfilled over a decade of reporting obligations and received a record suspension in November 2025 (which ended his reporting requirement going forward, though his information remained on the registry). The charge nonetheless remained live, and the parties agreed the constitutional questions were not moot. Roberts wanted a judicial ruling on whether the provisions were valid at all — not just relief for himself.

Key Legal Question:

Does the provincial sex offender registry, with its mandatory registration of all convicted sex offenders and automatic lifetime reporting for those with multiple convictions, comply with s. 7 of the Charter? Or do these provisions deprive offenders of liberty in a manner that is overbroad — sweeping in people whose inclusion serves no real connection to the law’s purpose?

The Ndhlovu Precedent

The ruling turns heavily on R. v. Ndhlovu, 2022 SCC 38, in which a majority of the Supreme Court of Canada struck down analogous provisions in the federal Sex Offender Information Registration Act (SOIRA). In Ndhlovu, the Court found that mandatory registration and lifetime reporting for multiple offenders were overbroad — going further than necessary to achieve their legislative purpose — and thus breached s. 7 without justification under s. 1.

The respondent (the Attorney General of Ontario) argued strenuously that Christopher’s Law should be treated differently. The provincial registry, it submitted, has a distinctly emphasized purpose: assisting police in time-sensitive investigations, particularly child abductions. Legislative history, Auditor General reports, and the testimony of two police witnesses were marshalled to show the registry’s operational advantages — including 24/7 direct access for over 1,400 authorized users, real-time geocoded data, and the capacity to run proximity searches against roughly 200 criteria within minutes.

Justice Garg’s Analysis

Justice Garg accepted that the provincial registry operates with greater operational agility than its federal counterpart, and acknowledged the registry’s genuine utility to police. But he concluded that these practical advantages did not translate into a constitutionally distinct purpose for the lifetime reporting and mandatory registration provisions specifically.

On lifetime reporting, the Court found that the provision’s purpose — giving police longer access to information about offenders at greater risk of reoffending — is the same as SOIRA’s. The specific text of s. 7(1)(c) of Christopher’s Law, which triggers lifetime reporting on conviction for more than one sex offence, says nothing about time-sensitive investigations. It is simply a recidivism-risk proxy. And, as expert evidence from Ndhlovu established, multiple convictions entered at a single proceeding do not reliably indicate greater recidivism risk. The provision therefore captures some offenders for whom it serves no purpose, making it overbroad.

The argument that record suspensions provide an adequate off-ramp was addressed but ultimately rejected. The record suspension framework does not require an explicit assessment of current risk, certain offenders are ineligible entirely, and — critically — the Supreme Court in Ndhlovu did not treat a similar termination-order mechanism in SOIRA as curing the constitutional defect.

On mandatory registration, the analysis followed similar lines. While sex offenders as a statistical class face an elevated average risk of reoffending, that group-level fact does not justify registration of every individual within the class. The claim that “a registry with only 90% of sex offenders was no registry at all” was rejected as an unproven premise inconsistent with Ndhlovu’s reasoning.

The Court also addressed the argument that earlier Ontario Court of Appeal decisions (R. v. Dyck, 2008, and G. v. Ontario, 2019) remained binding on the provincial law. Justice Garg concluded that Ndhlovu, decided by the Supreme Court, now provides the controlling constitutional framework. The Dyck analysis was premised on a characterization of the liberty intrusion as “modest” — a characterization the Supreme Court’s majority rejected.

What the Ruling Does Not Say

It bears emphasizing what Justice Garg was careful to note: the decision is not a condemnation of sex offender registries as a concept, nor a finding that the Ontario registry is without value. The registry’s work — and the officers who administer and rely on it — was expressly recognized as important. The ruling targets the automatic, indiscriminate breadth of two specific provisions, not the existence of the registry itself.

As a provincial court judge, Justice Garg also lacked jurisdiction to make a formal declaration of invalidity under s. 52 of the Constitution Act, 1982. His ruling is that the provisions are unconstitutional as applied to Roberts, and the appropriate remedy is a stay of the charge. A binding declaration of invalidity would require a Superior Court proceeding.

What Comes Next?

The federal government amended SOIRA following Ndhlovu to reintroduce a measure of judicial discretion: registration is no longer purely automatic, and courts can decline to impose it in certain circumstances. Ontario has yet to make equivalent amendments to Christopher’s Law. Justice Garg’s ruling signals — though it does not compel by way of formal declaration — that similar legislative reform at the provincial level may be necessary to bring the regime into constitutional compliance.

The ruling is likely to be influential in any future Superior Court challenge to Christopher’s Law. Whether the Crown appeals, or whether the provincial legislature acts proactively, remains to be seen. In the meantime, the case stands as a reminder that the scope of a law, no less than its purpose, must be calibrated to what the Constitution permits.
