A recent 911 service disruption lasting approximately 87 minutes in multiple Canadian provinces was attributed to an unforeseen software bug in Bell’s system, as stated in a report released by the company. The incident, which occurred at 3:13 a.m. ET on September 17, affected Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island.
Bell clarified that the outage was not a result of a cyber attack or any planned or unplanned changes. The issue stemmed from a hidden software flaw impacting components of Bell’s NG9-1-1 system, designed to enable the public to relay detailed emergency information to responders for improved situational awareness.
Following the identification of the root cause, Bell restored service by 4:40 a.m. and later implemented a permanent fix to prevent future occurrences. The outage disrupted services across the six provinces, with the majority of calls managed successfully by backup systems during the disruption, according to the report submitted to the CRTC.
Despite some missed legacy voice calls, none of the incidents resulted in critical public safety concerns. Bell emphasized its commitment to ensuring the reliability and continuous enhancement of emergency calling services to enable Canadians to seek help when needed.
The report also highlighted that initial alarms at the onset of the outage failed to trigger a prompt crisis response as intended. A response team was only alerted about the issue 24 minutes later, leading to a resolution by 4:40 a.m. Bell is investigating the alarm failure and has bolstered monitoring mechanisms for added security measures.
Specific details surrounding the software flaw and Bell’s system were redacted to prevent potential exploitation by hackers, with the company stressing the importance of safeguarding the integrity of the 911 network. Holly Barkwell of the National Emergency Number Association praised the resilience of Canada’s 911 system, acknowledging the imperfections inherent in technology.
The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by March 31, a deadline extended to 2027.
