An outage that disrupted 911 services for nearly 90 minutes in multiple Canadian provinces last month was caused by a previously unidentified bug in Bell’s software, the company disclosed in a recent statement. The incident, which affected Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island, occurred at 3:13 a.m. ET on Sept. 17, according to the report.
Bell clarified that the outage was not a result of a cyber attack or any planned or unplanned changes. The glitch impacted components of Bell’s advanced 911 system, called NG9-1-1, which enables the public to provide detailed emergency information to dispatchers for better response coordination by emergency services.
The company managed to identify and rectify the root cause, restoring service by 4:40 a.m. and implementing a permanent solution shortly after. Although the disruption affected service across six provinces, the majority of calls were successfully handled by backup systems during the incident.
Bell assured that none of the missed calls led to critical safety issues and emphasized its commitment to enhancing the reliability of emergency calling services. The outage was the first of its kind since the system’s launch in early 2022.
In a comprehensive report presented to the Canadian Radio-television and Telecommunications Commission (CRTC), Bell acknowledged that early alarms at the onset of the outage failed to trigger an immediate crisis response. The response team was not alerted to the issue until later, causing a delay in resolving the problem.
Bell is currently investigating why the initial alarms did not function as expected and has introduced additional monitoring mechanisms to prevent future disruptions. The company is also conducting a thorough review of its system and sharing insights with other service providers to improve emergency response capabilities.
To safeguard against potential security risks, Bell withheld specific details about the software flaw that caused the outage, citing concerns about potential exploitation by hackers. The company stressed the importance of maintaining the integrity of the 911 network to ensure public safety.
911 services in Canada are managed by regional legacy telephone providers, with Bell overseeing service in several provinces while other regions are covered by different providers. Despite the recent outage, industry experts emphasize the overall resilience of Canada’s 911 system while acknowledging the ongoing challenges in maintaining flawless technology.
The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by a set deadline, which was extended by two years in early 2025 to facilitate a smoother transition to more advanced emergency response technologies.
