  • Loblaw detected a data breach involving basic customer information.
  • No passwords, health data, or credit card information were compromised.
  • Customers will be logged out of their accounts as a security measure.

Loblaw is investigating a data breach after detecting suspicious activity on a non-critical segment of its IT network. A criminal third party accessed basic customer information, including names, phone numbers, and email addresses. However, the investigation indicates that passwords, health data, and credit card information were not compromised. Customers have been notified and will be automatically logged out of their accounts, requiring them to sign back in. The company's financial services subsidiary, PC Financial, was not affected by the breach. This incident follows Loblaw's recent report of fourth-quarter revenue falling below analysts' estimates, attributed to weak consumer spending amid high inflation. The investigation is ongoing as Loblaw works to secure its systems and mitigate any further risks.
