Wasn't impressed to get this email yesterday. Apparently, 38.3 million Canadian Tire accounts were breached in October, with very little media coverage and no communication from Canadian Tire itself.

Have I Been Pwned: Canadian Tire Data Breach

In October 2025, retailer Canadian Tire was the victim of a data breach that exposed almost 42M records. The data contained 38M unique email addresses along with names, phone numbers and physical addresses. Passwords were stored as PBKDF2 hashes and for a subset of records, dates of birth and partial credit card data were also included (card type, expiry and masked card number). In its disclosure notice, Canadian Tire advised that the incident did not impact bank account information or loyalty program data.

Have I Been Pwned

@chad

I share the same sentiments. I can accept that breaches occur (for both technical and human reasons) but failing to disclose it to those whose data was breached is unacceptable.

@RantingCanuck it makes for two breaches/vulnerabilities in the last six months mishandled by Canadian companies.
@chad Canadian Tire is yet another company that doesn’t allow you to change your email address. You know, for “security.” 🙄 Also? Their database included previous email addresses, not just the current one. It could not be any more clear that Canadian Tire has resigned themselves to having their lunch eaten by Amazon.

@dougcuff how so? I mean that's awful, but I'm not seeing the connection--oh wait for online shopping. I get it.

I'm genuinely shocked that any Canadian would still shop at Amazon.

@chad I wonder if this means it is the whole Canadian Tire group, including Sportchek and Mark’s.
@ehushagen I'm assuming they hit Triangle, so yes.
@chad I heard something about this yesterday...not a good look for crappy tire...need to get off their ass and notify, etc...
@chad some people in the UK also got notifications, possibly CTC backends one of the t[iy]re retailers over there (Black Circles?).
