How to Dispute Errors on Your Credit Report in Canada: Step-by-Step Guide

Mar 20, 202620 min read

Your credit report is one of the most important financial documents in your life. It determines whether you get approved for a mortgage, car loan, credit card, or even an apartment rental. But what happens when that report contains errors — information that is flat-out wrong?

Credit report errors are more common than most Canadians realize. Studies have shown that a significant percentage of credit reports contain at least one error, and some of those errors are serious enough to lower your credit score by dozens — or even hundreds — of points. For Canadians already dealing with bad credit, a single unwarranted negative item can be the difference between approval and rejection.

The good news: Canadian law gives you the right to dispute errors on your credit report, and both Equifax Canada and TransUnion Canada are legally obligated to investigate and correct legitimate mistakes. This guide walks you through every step of the dispute process — from identifying errors to escalating unresolved issues to federal regulators.

Why Credit Report Errors Are More Common Than You Think

Canada’s credit reporting system relies on hundreds of lenders, collection agencies, and financial institutions voluntarily submitting data to Equifax and TransUnion. Each data submission is an opportunity for human error, software glitches, or miscommunication. When you multiply that across millions of accounts and years of reporting history, errors become almost inevitable.

Errors can come from many sources:

• Creditor reporting mistakes: A lender accidentally reports a payment as late when it was on time
• Mixed files: Your credit file gets confused with someone else’s — especially common with similar names
• Identity theft: Someone opens accounts in your name that appear on your report
• Outdated information: A collection account that should have been removed after 6–7 years is still showing
• Duplicate accounts: The same debt appears twice, making it look like you owe double
• Incorrect personal information: Wrong address, wrong employer, wrong date of birth
• Closed account errors: An account you closed shows as still open or delinquent
• Paid debts still showing as outstanding: A collection you paid is still listed as unpaid

Re-aging is when a creditor or collection agency illegally resets the clock on an old debt, making it appear newer than it actually is. This extends how long the negative item stays on your report. If a collection account from 8 years ago suddenly has a recent date, that’s a red flag worth disputing immediately.

Step 1: Get Your Credit Reports From Both Bureaus

Before you can dispute anything, you need to know what’s on your reports. Canada has two major credit bureaus — Equifax Canada and TransUnion Canada — and lenders may report to one, both, or neither. That means your reports at each bureau can look quite different.

You are entitled by law to one free credit report per year from each bureau. You can request these in several ways:

Getting Your Free Equifax Canada Report

Getting Your Free TransUnion Canada Report

Always pull both reports simultaneously. An error on one bureau’s report won’t automatically be fixed by disputing it with the other. You need to review and dispute each bureau’s report separately if both contain errors.

Step 2: Review Your Reports Thoroughly

When your reports arrive, don’t just glance at them. Set aside an hour to go through every section carefully. Credit reports can be confusing to read, but understanding the structure helps you spot problems faster.

Sections to Check on Your Credit Report

Personal Information Section: Check your full name, date of birth, current and previous addresses, and Social Insurance Number (SIN). Even minor discrepancies here can cause mixed files — where your credit history gets confused with someone else’s.

Account History / Trade Lines: This is the core of your credit report. For every account listed, verify:

• Is this actually your account?
• Is the account status correct (open/closed/delinquent)?
• Are the payment history markers accurate?
• Is the balance correct?
• Is the account type correct (revolving vs. installment)?
• Are the dates correct (opened, closed, last payment)?

Collections Section: Any account sent to collections should be reviewed carefully. Check whether:

• You actually owe this debt
• The original creditor is correctly identified
• The amount is accurate
• The date of last activity is correct (this affects when it falls off)
• A paid collection is still showing as unpaid

Public Records Section: Bankruptcies, consumer proposals, and judgments appear here. Verify the dates and discharge status are accurate.

Inquiries Section: Check for hard inquiries you don’t recognize. An unfamiliar inquiry could be a sign of identity theft or a creditor pulling your report without your permission.

Step 3: Categorize the Errors You Find

Not all credit report errors are created equal. Some are minor administrative mistakes that won’t affect your score. Others are serious inaccuracies that could be costing you points and loan approvals. Understanding which category your errors fall into helps you prioritize your disputes.

High-Priority Errors (Dispute Immediately)

• Accounts you never opened (possible identity theft)
• Incorrect payment statuses (showing late when you paid on time)
• Paid collections still showing as unpaid
• Debts past the reporting limitation period still showing
• Incorrect balances that are significantly higher than reality
• Discharged bankruptcies still showing as active

Medium-Priority Errors (Dispute When Possible)

• Wrong account open/close dates
• Incorrect credit limits
• Duplicate accounts
• Wrong account type classification

Lower-Priority Errors (Still Worth Fixing)

• Old addresses listed incorrectly
• Former employer information wrong
• Minor personal information discrepancies

Step 4: Gather Your Supporting Documentation

The strength of your dispute depends almost entirely on the documentation you provide. Bureaus are not going to simply take your word that a creditor made a mistake — they need evidence. Here’s what to gather before you file:

Step 5: File Your Dispute — How to Do It With Equifax and TransUnion

Both bureaus offer online, mail, and phone dispute options. Online is generally the fastest, but mail disputes with documentation create a paper trail that can be valuable if you need to escalate later.

1. Identify the specific item(s) you want to dispute

   Be precise. Note the creditor name, account number (partial), the specific error, and what the correct information should be. Vague disputes like “this account is wrong” are less effective than “this account shows a missed payment in March 2023, but I have bank records proving payment was made on March 15, 2023.”



2. Write your dispute letter or complete the online form

   Both bureaus have online dispute portals. If disputing by mail, write a clear, professional letter. Include your full name, current address, date of birth, and the last four digits of your SIN to help them locate your file.



3. Attach copies of your supporting documents

   Never send originals. Make photocopies or scan documents and attach them to your dispute. Label each document clearly so the investigator knows what it relates to.



4. Send your dispute and keep records

   If mailing, use registered mail and keep the tracking number. If filing online, screenshot the confirmation page and note the dispute reference number. Date everything.



5. Wait for the investigation result

   Equifax and TransUnion typically have 30 days to investigate, though the process can take up to 45 days. They will contact the original creditor to verify the information. You should receive a written response.



6. Review the outcome and follow up if needed

   If the error is corrected, request a new copy of your updated report to confirm the change. If the bureau upholds the original information, you have options to escalate (see below).

How to File a Dispute With Equifax Canada

Online: Log in to your Equifax account at equifax.ca and navigate to the “Dispute” section. You can identify the specific item and describe the error.

By Mail: Send your dispute letter and supporting documents to:

Equifax Canada Co.
Consumer Relations Department
Box 190 Jean Talon Station
Montreal, Quebec H1S 2Z2

By Phone: Call 1-800-465-7166. Note that phone disputes may be harder to document — follow up in writing.

How to File a Dispute With TransUnion Canada

Online: Log in to transunion.ca and use the dispute center in your account dashboard.

By Mail: Send your dispute letter and supporting documents to:

TransUnion Consumer Relations
P.O. Box 338, LCD1
Hamilton, Ontario L8L 7W2

By Phone: Call 1-800-663-9980. Again, follow up in writing for documentation purposes.

Sample Dispute Letter Template

Here is a template you can adapt for your own dispute. Replace the bracketed information with your own details.

In Canada, credit reporting is governed by both federal and provincial law. Federally, the Personal Information Protection and Electronic Documents Act (PIPEDA) gives you the right to access your personal information held by organizations (including credit bureaus) and to challenge its accuracy. Several provinces also have their own consumer reporting acts that may provide additional rights. In Ontario, the Consumer Reporting Act; in British Columbia, the Business Practices and Consumer Protection Act; in Alberta, the Consumer Protection Act.

Step 6: Understanding the Investigation Process

When you file a dispute, the bureau doesn’t simply take your word for it — they contact the original creditor (called the “data furnisher”) and ask them to verify the information. The creditor then has a limited time to respond. Here’s what typically happens behind the scenes:

1. The bureau receives your dispute and opens a case
2. The bureau sends an automated inquiry to the creditor who reported the information
3. The creditor reviews their records and either verifies, updates, or deletes the item
4. The bureau updates your report based on the creditor’s response
5. You receive written notification of the outcome

If the data furnisher (creditor or collection agency) does not respond to the bureau’s inquiry within the investigation period, the bureau is required to remove the disputed item from your report. This is why it’s important to dispute even items you’re uncertain about — the burden shifts to the creditor to verify their own records.

Provincial Differences in Credit Reporting Rules

While federal PIPEDA applies across Canada, provinces have their own consumer reporting legislation that may offer stronger protections. This table summarizes key provincial rules:

Step 7: Adding a Consumer Statement to Your Credit Report

If a bureau investigates your dispute and upholds the original information — meaning they believe the creditor’s records over yours — you still have one more option before escalating: adding a consumer statement to your credit report.

A consumer statement is a short note (usually up to 100 words) that you can add to your credit file explaining your side of the story. It won’t change your credit score, but it will be visible to any lender who pulls your full credit report. This can be particularly useful in situations like:

• A disputed collection account that the bureau won’t remove
• A late payment that occurred due to circumstances beyond your control (medical emergency, job loss)
• An account error that you believe is wrong but can’t yet prove

To add a consumer statement, contact the bureau directly and request the process. Both Equifax and TransUnion allow this. The statement will remain on your file until you request its removal or the underlying item is removed.

Step 8: Escalating to the Financial Consumer Agency of Canada (FCAC)

If you’ve filed a dispute with the bureau, received a result you believe is wrong, and are unable to resolve the issue with the bureau or the original creditor, it’s time to escalate to Canada’s federal financial consumer regulator: the Financial Consumer Agency of Canada (FCAC).

The FCAC oversees federally regulated financial institutions and enforces federal consumer protection laws, including those related to credit reporting. While the FCAC can’t force a bureau to change your report, they can investigate complaints against federally regulated financial institutions and take enforcement action if warranted.

1. Exhaust bureau and creditor options first

   The FCAC will generally expect you to have already tried to resolve the issue directly with the bureau and the original creditor. Document every step of your attempts.



2. File a complaint with the FCAC

   Visit fcac-acfc.gc.ca and use the online complaint form. You can also call 1-866-461-3222. Describe your situation clearly and attach all relevant documentation.



3. Contact your provincial regulator if applicable

   For issues with provincially regulated credit reporting activities, contact your provincial consumer protection office. In Ontario, that’s the Ministry of Public and Business Service Delivery.



4. Consider the Office of the Privacy Commissioner (OPC)

   If the dispute involves how a bureau or creditor is handling your personal information under PIPEDA, you can also file a complaint with the Office of the Privacy Commissioner of Canada (OPC) at priv.gc.ca.



5. Seek legal advice for serious cases

   If an error has caused you demonstrable financial harm — for example, you were denied a mortgage because of a false delinquency — you may have grounds for legal action. Consult a consumer rights lawyer or a not-for-profit credit counselling organization.

If you need help navigating the dispute process, free credit counselling is available through:

• Credit Counselling Society: nomoredebts.org — free confidential counselling
• Canadian Association of Credit Counselling Services (CACCS): caccs.ca
• Option consommateurs (Quebec): option-consommateurs.org
• FCAC Financial Literacy tools: canada.ca/en/financial-consumer-agency

What Happens to Your Credit Score After a Dispute?

If your dispute is successful and an error is removed or corrected, you can expect your credit score to change — but the timing and magnitude depend on what was corrected.

Identity Theft and Credit Report Disputes

If you find accounts on your credit report that you didn’t open, or see inquiries from lenders you’ve never dealt with, you may be a victim of identity theft. This requires a more urgent response than a typical error dispute.

Steps to take if you suspect identity theft:

1. Place a fraud alert on your credit file: Contact both Equifax and TransUnion immediately. A fraud alert tells lenders to take extra steps to verify your identity before opening new accounts.
2. Request a credit freeze: A credit freeze (available in Canada) prevents new credit from being opened in your name until you lift the freeze.
3. File a police report: Get a police report number — you’ll need this when disputing fraudulent accounts.
4. Report to the Canadian Anti-Fraud Centre: Call 1-888-495-8501 or visit antifraudcentre.ca.
5. Notify affected creditors directly: Contact the lenders where fraudulent accounts were opened.

Hard inquiries you don’t recognize are one of the earliest warning signs of identity theft. Even if no accounts have been opened yet, an unrecognized inquiry means someone applied for credit in your name. Act immediately.

How Long Does the Dispute Process Take?

The total timeline from filing your dispute to seeing a corrected credit report can vary, but here’s a general framework:

Common Mistakes to Avoid When Disputing

Many Canadians make avoidable mistakes during the dispute process that slow things down or reduce their chances of success. Here’s what to watch out for:

• Disputing accurate negative information: Don’t dispute a legitimate late payment just because you don’t like it. Bureaus will verify it with the creditor, it will be confirmed, and it stays. Focus on genuine errors.
• Sending vague disputes: “This account is wrong” gives the bureau nothing to work with. Be specific about what is incorrect and what the correct information should be.
• Not keeping copies of everything: If your case escalates, you’ll need a complete paper trail. Keep copies of every letter, every document, every confirmation number.
• Forgetting to follow up: If you don’t hear back within 45 days, follow up. Don’t assume silence means the error was corrected.
• Only disputing with one bureau: If the same error appears on both reports, you need to dispute with both. They don’t share dispute outcomes.
• Using a credit repair company: Be very wary of companies that promise to “fix” your credit for a fee. Many are scams. You can do everything a credit repair company does for free on your own.

Preventing Future Credit Report Errors

Once you’ve resolved existing errors, take steps to reduce the chance of new ones appearing:

• Monitor your credit regularly: Both bureaus offer monitoring services. Free alternatives include apps like Borrowell (uses Equifax) and Credit Karma Canada (uses TransUnion).
• Review your report annually: Even if nothing feels wrong, pull both reports once a year to check for issues early.
• Keep records of payments: Save payment confirmations, especially for accounts you’ve paid off or settled.
• Notify creditors when you change address: Returned mail can lead to missed statements, which leads to unnoticed delinquencies.
• Follow up after paying off debts: Confirm with the creditor that they’ve reported the payoff correctly, and then verify on your credit report 30–60 days later.

Conclusion: Take Control of Your Credit File

Your credit report is not infallible. It’s built from thousands of data points submitted by hundreds of different entities, and errors creep in. The difference between Canadians who suffer for years under the weight of inaccurate information and those who take control is simple: action.

The dispute process is not complicated. It requires patience, organization, and persistence — but it costs you nothing but time. And the payoff — an accurate credit report that reflects your true financial history — can open doors to lower interest rates, better loan terms, and financial opportunities you may have thought were out of reach.

Start today. Pull your reports from both Equifax Canada and TransUnion Canada. Read them carefully. And if you find something wrong, you now know exactly what to do about it.
