Identity Theft in Canada: How It Works and What to Do

Identity theft is when someone steals your personal information, SIN, driver’s licence, banking details, or login credentials and uses it to impersonate you. In Canada, that can mean new credit in your name, drained accounts, false police records, or stolen government benefits. Understanding how identity theft works is the first step to spotting it early and limiting the damage.

What is identity theft under Canadian law?

The RCMP distinguishes identity theft (acquiring someone’s personal information for criminal purposes) from identity fraud (the deceptive use of that information). The Criminal Code addresses identity information in section 402.1 and related offences. Practically, victims face two common patterns:

• True-name identity theft — the thief opens new credit cards, loans, phone plans, or bank accounts using your details.
• Account takeover — the thief hijacks accounts you already have, often by changing the mailing address or resetting passwords, then runs up charges before you notice.

What types of identity theft should you watch for?

• Financial — the most reported form: unauthorized purchases, tax refund fraud, or new credit lines.
• Criminal / cloning — someone uses your identity when dealing with police or to hide their own record.
• Medical — misuse of health coverage or insurance benefits in your name.
• Child identity theft — a minor’s SIN or identity is used for credit or benefits, often unnoticed for years.

Threats range from stolen mail and phishing to elaborate account takeovers. Treat every request for personal data as hostile until you verify it, see our guide on how to protect yourself from scammers, hackers, and thieves.

What information do identity thieves target?

• Full name, date of birth, and address
• Social Insurance Number (SIN)
• Driver’s licence and passport numbers
• Mother’s maiden name and other security-question answers
• Usernames, passwords, and one-time codes
• Credit/debit card numbers, expiry dates, and CVV
• Bank account numbers, PINs, and signatures

With that data, criminals can access or open accounts, apply for loans, make purchases, claim benefits, or conceal other crimes. Online transactions make misuse easier because there is often no face-to-face check.

How do you know if your identity was stolen?

Monitor bank and credit-card statements often, and review your credit reports with Equifax Canada and TransUnion Canada for unfamiliar accounts or inquiries. Warning signs include collection calls about debts you do not recognize, mail that stops arriving, unexpected credit denials, or login alerts you did not trigger. Familiarize yourself with common fraud warning signs so pressure tactics and phishing stand out sooner.

What should you do if you are a victim?

1. File a report with your local police and keep the file number.
2. Call your bank and card issuers; freeze or replace compromised cards and change passwords.
3. Place a fraud alert with Equifax and TransUnion and review both credit files.
4. Report the incident to the Canadian Anti-Fraud Centre.

Document dates, phone numbers, screenshots, and correspondence. When losses are large, accounts keep reopening, or you need evidence for counsel or insurers, a structured digital investigation can help preserve trails and support recovery.

How can you reduce the risk of identity theft?

• Ignore unsolicited emails, texts, or calls that ask for SIN, banking, or one-time codes.
• Carry only the ID you need; store the rest securely.
• Shred documents with account numbers before recycling.
• Shield PINs at ATMs and terminals; never write PINs on cards.
• Use unique passwords and multi-factor authentication on email and banking.
• When you move, update Canada Post and every financial institution so mail is not redirected to a thief.
