A proposed Ontario class action filed on November 2 alleges that Loblaw failed to protect customer data and waited months to notify affected people, according to The Standard. Loblaw confirmed it had been served and intends to contest certification. Loblaw stock traded at 44.50 euros on Lang & Schwarz at 16:32 CET on Friday, November 13, 2026. That was 2.06 percent above the 43.60-euro level in our report of November 11.

What the lawsuit alleges

The claim concerns a February 2026 breach that affected personal information belonging to about two million Canadians. The reported information includes names, email and postal addresses, phone numbers, dates of birth, loyalty account numbers, purchase-order details and incomplete payment-card information.

The allegations have not been tested in court. The proceeding must receive judicial certification before it can continue as a class action, making the current filing an early legal step rather than a finding of liability.

Privacy risk and customer trust

The claim also challenges Loblaw's offer of free credit monitoring, arguing that two years of coverage may not address the longer-term risks linked to exposed personal information. The company has said that extensive analysis, de-duplication and validation were needed to establish the scope of the incident and identify affected customers.

For investors, the case adds legal, remediation and governance considerations to the operational impact of the breach. The proceedings may also keep customer trust and data-security controls in focus as Loblaw manages the consequences.
