Was your data in the Canadian Tire breach?

Canadian Tire (canadiantire.ca) suffered a data breach in 2025 that exposed around 38,306,562 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.

What happened

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.

What was exposed, and why it matters

Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Canadian Tire breach exposed and what each item actually enables:

Also listed in this breach: Dates of birth, Email addresses, Genders, Names, Partial credit card data, Passwords, Phone numbers, Physical addresses.

What to do if you were affected

These steps are ordered for this specific breach — the most urgent action given what leaked comes first.

1. 01Payment or bank details
   Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
2. 02Passwords
   Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
3. 03Home addresses
   Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
4. 04Dates of birth
   Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
5. 05Phone numbers
   Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
6. 06Confirm you were actually in it
   Run a free scan before you spend time on the steps above.

This breach put your details on data-broker sites

Because Canadian Tire exposed home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?

This breach is recent, so the data is actively traded and the risk is at its highest right now.

Passwords are the reason breach age matters less than people expect. Leaked credentials are compiled into wordlists that get tried against new services for years afterwards, so a password exposed here is unsafe to use anywhere, ever again.

Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
