Canadian retailer Loblaw investigates data breach

Loblaw confirmed no passwords, health data, or credit card details were accessed; customers must re-authenticate after the breach of basic contact information.

  • On March 10, 2026, Loblaw Companies Limited announced it is investigating a data breach after identifying suspicious activity where a criminal third party accessed basic customer contact information.
  • Unusual activity in a contained, non-critical part of Loblaw's IT network prompted the investigation, as the Company said suspicious activity was detected.
  • Security measures included securing the network and notifying customers, and all customers will be automatically logged out and must log back in to access the Company's digital services.
  • Loblaw's investigation indicates customers' passwords, health information and credit card data were not compromised, and PC Financial was not impacted, with no expected effect on financial performance.
  • The retailer, Canada's food and pharmacy leader with more than 220,000 colleagues, had reported fourth-quarter revenue below analysts' estimates last month and cautioned outcomes depend on its ongoing forensic investigation.
