The City of Ottawa experienced a data breach on its My ServiceOttawa online portal, exposing the email and physical addresses of approximately 2,454 users. The incident occurred on October 3 due to an isolated system error in the service request lookup tool, which allowed an unauthorized user to exploit a bot to access service requests linked to other accounts. No financial, password, or highly sensitive personal information was compromised. The city detected the breach promptly, blocked the unauthorized user, and conducted a thorough analysis to confirm the limited scope of exposure. Affected individuals were notified, and additional security measures were implemented to prevent recurrence. The city emphasized that the incident was contained to the lookup tool and that My ServiceOttawa itself remained secure.
