Identity Theft and Your Credit in Canada 2025

Identity theft occurs when someone uses your personal information — your name, Social Insurance Number, date of birth, or financial account details — to commit fraud, most commonly by opening credit accounts in your name. The resulting fraudulent accounts and missed payments (since you don't know about them or make payments) can severely damage your credit score, sometimes before you even know it's happening.

Warning Signs of Identity Theft

You may be a victim of identity theft if you notice:

Immediate Steps If You're a Victim

  1. File a police report: Contact your local police service. Get a copy of the report — you'll need the report number for every dispute you file.
  2. Contact both credit bureaus:
    • Equifax Canada: 1-800-465-7166 or equifax.ca
    • TransUnion Canada: 1-800-663-9980 or transunion.ca
    Request fraud alerts on both files and ask for free copies of your complete credit reports.
  3. Review both reports line by line: Identify every account and inquiry you didn't initiate.
  4. Contact each affected creditor's fraud department: Report the fraudulent account and initiate their fraud resolution process.
  5. Report to the Canadian Anti-Fraud Centre: antifraudcentre.ca or 1-888-495-8501.
  6. Consider contacting Service Canada: If your SIN was compromised, contact Service Canada about protecting it.

Disputing Fraudulent Accounts on Your Credit Report

File disputes with both Equifax and TransUnion for every fraudulent account and inquiry. Include:

Bureaus must investigate and remove confirmed fraudulent items. This typically takes 30–45 days per dispute. With a police report, fraudulent items are usually removed — not just marked as disputed.

How Identity Theft Affects Your Credit Score

Fraudulent accounts harm your score in multiple ways:

In the worst cases, multiple fraudulent accounts with maxed balances and collections can drop a 750 score to below 500 within a few months.

How Long Does Credit Recovery Take After Identity Theft?

Once all fraudulent items are successfully disputed and removed (typically 2–6 months), your score should recover to near its pre-theft level within 1–3 months. The key is getting every fraudulent item removed — not just some of them. Any remaining fraudulent negative entries will continue to drag your score down.
