TL;DR: Canadian Tire discovered unauthorized access to an e-commerce database on October 2, 2025. Have I Been Pwned later loaded about 42 million records, including 38.3 million email addresses. Accounts with Canadian Tire, SportChek, Mark’s/L’Équipeur and Party City were involved. Exposed data includes names, emails, phone numbers, addresses, hashed passwords and, for a small subset, dates of birth and partial card details. If you shopped online with any of these brands, assume you’re in it: change the password, watch for targeted phishing and ignore "Triangle points" texts.

What happened

According to SecurityWeek, Canadian Tire found that someone had accessed an e-commerce database on October 2, 2025. The company notified affected customers by email. It hasn’t publicly confirmed a total number of victims, but when the data reached Have I Been Pwned in late February 2026, it contained about 42 million records and 38.3 million unique email addresses.

That’s roughly one record for every person in Canada. Not every one is a separate human, of course. Some of us have a SportChek account from 2014 we’ve completely forgotten about, which is precisely the problem.

Which brands were included

The breach covered online accounts with:

What data was exposed

DataStatus
NamesExposed
Email addressesExposed
Phone numbers and physical addressesExposed (per HIBP)
GenderExposed (per HIBP)
PasswordsExposed as PBKDF2 hashes
Date of birthFewer than 150,000 accounts
Partial card data (type, expiry, masked number)A subset of records
Canadian Tire Bank dataNot involved, per the company
Triangle Rewards loyalty dataNot involved, per the company

Canadian Tire says the password and card information can’t be used to get into accounts or make purchases. PBKDF2 is a slow, deliberate hashing method, which is good news. "Hard to crack" still isn’t "impossible to crack" for a weak password, though.
