The Special Investigations Unit (SIU), Ontario’s police watchdog, is investigating the tragic death of a 23-year-old woman following a crisis intervention by Durham Regional Police. The incident, which unfolded in Oshawa on the evening of Thursday, April 23, 2026, has left the community searching for answers, especially as it involved a police interaction that led to the woman’s death shortly after being released from a hospital.
The sequence of events began around 9:30 p.m. when officers responded to a call about a woman who was reportedly in crisis in the area of Simcoe Street North and Winchester Road East. Authorities responded quickly, apprehending the woman and transporting her to Lakeridge Health Oshawa hospital for medical attention. It’s understood that she was admitted, evaluated, and then released back into the community shortly after her arrival.
However, the situation took a grim turn when hospital security later observed the woman in the parking garage. This prompted them to notify the police, who returned to the hospital to check on her well-being. Tragically, they discovered the woman lying on the ground below the parking garage, and efforts to revive her were unsuccessful. She was immediately brought back into the hospital but was pronounced dead shortly thereafter.
As per standard procedure for incidents involving death or serious injury in police custody, the SIU has taken over the investigation to determine the exact cause of death. In Ontario, the SIU investigates cases where civilians die or suffer serious injury after being involved with police officers, including those involving discharges of firearms or allegations of sexual assault. The agency is tasked with determining whether police actions contributed to the unfortunate outcome.
At this point, it remains unclear how the woman ended up outside of the hospital, and the SIU will be looking into whether any factors related to the police’s interaction with her played a role in her death. The SIU has already stated that the woman’s tragic passing will be thoroughly examined to provide transparency in the case.
The community, understandably shaken by the event, has been left with many questions. Police and the SIU are urging anyone with relevant information to come forward to aid the investigation. Anyone who might have witnessed something or has additional details is encouraged to contact the SIU through their hotline at 1-800-787-8529, or through their online reporting platform at www.siu.on.ca.
This investigation comes at a time when the public and law enforcement are paying close attention to incidents of police interactions with civilians, especially regarding mental health crises. Many are watching closely to see what information is revealed about this case and whether it leads to any changes in how law enforcement handles such situations in the future.
The family and friends of the woman have yet to make public statements, and their privacy is being respected during this difficult time. As for the Durham Regional Police, they have been cooperating fully with the SIU investigation and have offered their condolences to the family, but they have refrained from making any further comments until the investigation concludes.
The case remains ongoing, and the SIU is working tirelessly to uncover all of the facts to provide clarity for both the community and the woman’s family. This tragedy highlights the growing need for improved support systems for those in crisis, ensuring that their safety is prioritized at every step of the process.
