An outage lasting nearly 90 minutes affected 911 services in multiple Canadian provinces last month, with Bell attributing the issue to an undetected software bug. The disruption, which occurred at 3:13 a.m. ET on Sept. 17, impacted Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island.
Bell clarified that the incident was not a cyber attack or the result of any planned or unplanned changes. The glitch affected Bell’s NG9-1-1 system, intended to enhance emergency response by allowing the public to provide detailed information to dispatchers.
Bell swiftly identified and resolved the root cause by 4:40 a.m., implementing a permanent fix that morning. Although most calls were managed by backup systems during the outage, legacy voice calls routed through older systems were missed if they were directed to call centers using the new technology.
The outage did not lead to any critical public safety incidents, Bell assured, emphasizing its commitment to enhancing emergency calling services. The company acknowledged the need for continuous improvement and stated that steps have been taken to prevent a recurrence of the incident.
Reportedly, early alarms failed to trigger a crisis response as intended, delaying the resolution process. Bell has since deployed additional monitoring mechanisms as a fail-safe measure and is conducting a thorough review of its systems, including debriefing staff and sharing learnings with other service providers.
Specific details regarding the software flaw and system-wide information were redacted from the public report to prevent potential exploitation by hackers. Bell highlighted the importance of safeguarding the 911 infrastructure from vulnerabilities.
In Canada, 911 services are managed by regional legacy telephone providers, with Bell overseeing services in several provinces. The National Emergency Number Association emphasized the resilience of Canada’s 911 system while acknowledging the inevitability of technological issues.
The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by March 31, with a recent extension granted until 2027.
