Canadians could be part of proposed Canadian Tire class-action lawsuit
Canadians impacted by a massive nationwide data breach could be part of a newly proposed class-action lawsuit against Canadian Tire.
On July 24, KND Complex Litigation and Hammerco Lawyers LLP announced that they have commenced a proposed class action on behalf of Canadian Tire customers affected by a 2025 data breach.
“The proposed class action seeks to discover the facts regarding the data breach, promote corporate accountability and data governance practices across Canada’s retail sector, which is entrusted with highly sensitive personal information of Canadians, and recover compensation for affected customers,” reads the release.

On Oct. 2, 2025, Canadian Tire Corporation (CTC), the parent company of Canadian Tire, SportChek, Mark’s/L’Équipeur, and Party City, alerted customers to a data breach involving customer information in an e-commerce database.
According to the class-action website, it’s alleged that cybercriminals extracted around 42 million records from Canadian Tire’s backend database, affecting over 38 million customer accounts. Data included names, physical addresses, email addresses, phone numbers, encrypted passwords, and in some cases, birth dates and partial credit card details. The information was reportedly posted for sale on the Dark Web.
The proposed lawsuit alleges that Canadian Tire didn’t have adequate safeguards in place to protect customers’ data, despite what the claim describes as “a history of cyberattacks.” The company faces further allegations that it failed to properly investigate and communicate the full scope of the breach to its customers.
Daily Hive has reached out to Canadian Tire for a comment and will update this story once it receives a response.
