Ontario’s Major Case Management system emerged following the Paul Bernardo investigation to address structural failures in multi-jurisdictional policing. The 1993 case revealed that fragmented information sharing allowed mobile offenders to evade detection. Consequently, the province established a mandatory, disciplined methodology for organizing evidence and coordinating complex criminal investigations.
The current framework utilizes a command triangle to oversee strategy, investigations, and information integrity. This standardized approach prevents tunnel vision and ensures accountability by recording decision-making processes. While no system guarantees results, this model facilitates the linkage of violent offences and reduces reliance on informal communication between agencies.
The investigation of Paul Bernardo exposed what could happen when capable police services held separate pieces of the same case. Ontario’s Major Case Management system was built to make those pieces visible before another offence occurred.
By the time Paul Bernardo was arrested in February 1993, police had investigated sexual assaults in Scarborough, the abduction and murder of Leslie Mahaffy in Halton and Niagara, and the abduction and murder of Kristen French in St. Catharines. Information existed in different services and units. It did not reliably become one investigative picture.
The later review led by Justice Archie Campbell concluded that individual commitment could not compensate for structural failure. The central problem was not that no one was working. It was that information, priorities and responsibility were divided across jurisdictional lines while a mobile offender continued to operate.
Ontario’s response to serial-predator investigations became Major Case Management: a province-wide method for organizing evidence, decisions, personnel and links between complex cases.
What the Campbell Review Found
The Bernardo Investigation Review examined the work of multiple police services, the Green Ribbon Task Force, the Centre of Forensic Sciences and other institutions. It documented delayed forensic results, incomplete information sharing, the failure of relevant reports to reach the investigators who needed them, and the absence of a system capable of recognizing the whole pattern.
The lesson was broader than one case. A serial predator may select victims in one city, offend in another and leave evidence in a third. Conventional case ownership can turn geography into an investigative blind spot. A major-case system must preserve a clear command structure while allowing information to move beyond the agency that first received it.
The Creation of Ontario Major Case Management
Ontario began developing its Major Case Management system in 1997. A Public Safety Canada synopsis describes the original response as a five-year, $25-million initiative combining centralized oversight, standardized training, case-management software and a serial-predator coordination function. Major Case Management became mandatory for Ontario police services in 2005.
The point was not simply to create a larger database. Major Case Management is a disciplined investigative methodology. It assigns responsibility, records decisions, controls the flow of documents and tips, creates detailed chronologies and provides a way to compare one investigation with another.
Early public descriptions emphasized the PowerCase software platform. Software has changed over time. The enduring reform is the common method and legal framework, not a particular product name.
How the Current Framework Works
Ontario’s present requirements are set out in Ontario Regulation 394/23, under the Community Safety and Policing Act, 2019. The regulation identifies principles that would have addressed several failures described by Campbell: a consistent methodology, control of large volumes of information, strong team communication, detailed decision records, investigative planning and measures intended to prevent tunnel vision.
For a prescribed major case, the core command triangle consists of:
- A major case manager, responsible for strategy, resources and overall direction.
- A primary investigator is responsible for carrying out and coordinating investigative tasks.
- A file coordinator is responsible for the information management system and the integrity of the file.
Supporting roles can include field investigators, forensic identification personnel, a scene coordinator, a media liaison, and a victim liaison. The structure is designed to make responsibility visible. It also preserves the reasoning behind important decisions, allowing supervisors and later reviewers to understand not only what investigators did, but why.
Linked and Multi-Jurisdictional Investigations
The current regulation specifically addresses linked investigations and cases involving more than one police service. When information suggests separate investigations involve the same person, or are otherwise linked within the regulatory definition, notification and coordination requirements are triggered. A multi-jurisdictional command structure can then assign leadership and resolve responsibilities that might otherwise remain fragmented.
Ontario’s model also operates alongside the Violent Crime Linkage Analysis System, or ViCLAS, a national RCMP-managed system used to identify behavioural links among serious violent offences.
Major Case Management organizes the investigation; linkage analysis helps compare it with other cases. They are complementary functions, not interchangeable labels.
What Reform Can and Cannot Do
No information system can guarantee a serial offender will be identified. Data can be incomplete, witnesses can be mistaken, forensic testing takes time, and investigators still have to exercise judgment. A standardized system can itself become procedural clutter if information is entered poorly or warnings are not acted upon.
What Ontario Major Case Management changes is the default. A complex homicide or linked violent offence is no longer supposed to depend on informal memory, personal contacts or the hope that one investigator recognizes a name from another jurisdiction. The file is structured for comparison, accountability and transfer. The possibility of tunnel vision is treated as a management problem, not merely an individual failing.
The systemic failures in the Bernardo investigation cannot be undone by the framework they produced. Tammy Homolka, Leslie Mahaffy and Kristen French were already dead when the province began rebuilding its methods.
Ontario’s response to serial-predator investigations is therefore an institutional memorial of a severe kind: a set of rules written because the old arrangements had shown, in irreversible terms, where they could break.
