An error on your credit report is not a minor inconvenience. A single inaccurate collection account can drop your score by 50–100 points — the difference between qualifying for a mortgage at a competitive rate and being declined or paying a rate premium. A wrong credit limit entry inflates your apparent utilization, which alone can suppress your score by 20–40 points even when your actual spending behaviour has not changed. Canadian law gives you the right to dispute these errors at no cost, and both Equifax and TransUnion are legally required to investigate. This article is part of the Canadian credit scores hub.
This guide walks through the complete process: identifying errors, gathering evidence, submitting disputes, and escalating when the first attempt does not succeed.
Step 1: Get Your Reports from Both Bureaus
The first step is pulling your reports from both Equifax Canada and TransUnion Canada. The two bureaus operate independently — an error on one does not necessarily appear on the other, but if the creditor reports to both, the error may be duplicated. You need to check both.
Equifax and TransUnion are each required by provincial consumer reporting legislation to provide one free credit report annually by mail. You can request these at equifax.ca and transunion.ca respectively. For more frequent access without the mail delay, Borrowell provides free Equifax reports and scores monthly, and Credit Karma provides free TransUnion reports and scores monthly — both via soft pulls that do not affect your score.
Download or print both full reports and review every section: personal information, employment history, every account (open and closed), every inquiry, and every public record entry. The errors that cost the most are often ones people did not notice for months or years.
Step 2: Identify the Exact Error
Credit report errors fall into several recognizable categories. Knowing which type you are dealing with shapes both your evidence strategy and your dispute letter.
Accounts that are not yours are among the most damaging errors. They appear when two consumers have similar names and social insurance number digits — a phenomenon called a “mixed file.” A missed payment or collection on an account you never opened can decimate a score with no warning. You do not need to prove anything other than that the account is not yours; the burden shifts to the creditor to verify it belongs to you.
Paid debts showing as outstanding are extremely common. When you pay off a collection or settle a charged-off account, the creditor is supposed to update their reporting to the bureaus. Many do not, or do so slowly. A balance of $0 and a status of “paid” is the correct outcome; “owing” or “in collections” after full payment is an error.
Incorrect credit limits are a subtler problem. If your actual limit is $10,000 but the bureau shows $5,000, your utilization on that card appears double what it actually is. High utilization is one of the heaviest scoring factors — this error alone can cost 20–40 points without any change in your spending behaviour.
Outdated negative information that should have aged off is also reportable. Most negative entries in Canada must be removed 6–7 years from the date of the event. An old missed payment from eight years ago that is still on your report is a compliance violation, not just an error.
| Error Type | What to Look For |
|---|---|
| Account not yours | Creditor name and account number you do not recognize |
| Paid debt showing unpaid | Status shows “owing” or “in collections” after you paid |
| Wrong credit limit | Your actual limit is higher than what is shown |
| Duplicate tradeline | Same account appears twice under different entries |
| Outdated negative information | Negative item more than 6–7 years old still appearing |
| Wrong personal information | Incorrect address, name misspelling, wrong SIN |
| Fraudulent account | Account opened without your knowledge or consent |
Step 3: Gather Your Documentation
A dispute without documentation is a statement of opinion. A dispute with documentation is a factual record the bureau must evaluate. The stronger your evidence, the faster and more likely a correction is made.
For a paid debt showing as outstanding, you need your bank statement showing the payment transaction and ideally the creditor’s written confirmation of payment — a “paid in full” letter, a settlement confirmation email, or a final statement showing a zero balance. Both together are nearly unassailable.
For an account that is not yours, the law places the verification burden on the creditor, not on you. You state the account is not yours; the creditor must prove it is. A police report or CRA identity confirmation letter strengthens the dispute if identity theft is suspected.
For a wrong credit limit, a copy of your credit card agreement or an account statement showing the correct limit is sufficient. The creditor’s own records will reflect the correct number.
For outdated information, calculate the timeline: the date of the original missed payment or collection event, plus 6–7 years, compared to today’s date. If that period has elapsed, the entry must be removed regardless of whether the debt was paid.
| Error Type | Key Supporting Documents |
|---|---|
| Paid debt showing unpaid | Bank statement of payment; creditor paid-in-full letter |
| Account not yours | Statement that it is not yours; police report if fraud suspected |
| Wrong credit limit | Credit card agreement or account statement showing actual limit |
| Outdated tradeline | Timeline calculation from date of event to today |
| Duplicate entry | Printout of both entries highlighted to show they are identical |
| Identity theft account | Police report; CRA identity confirmation |
Step 4: Submit Your Dispute
Online Dispute (Fastest)
Equifax Canada: equifax.ca → Credit Report → Dispute. Select the account, describe the error specifically, state the correction you are requesting, and attach scanned copies of your supporting documents.
TransUnion Canada: transunion.ca → Dispute Centre. The same process — select the item, describe the error, attach documents.
Online submission is the fastest route and creates a dated record of your dispute. The bureau’s investigation clock starts from the date the dispute is received.
Dispute by Mail (For Complex Cases or Document-Heavy Disputes)
If your evidence is extensive or the situation is complex, a mailed letter with physical document copies provides a clear paper trail. Send copies only — never originals. Use registered mail so you have proof of delivery and the date received.

Re: Dispute of Inaccurate Information — Credit Report
To Whom It May Concern:
I am writing to dispute inaccurate information on my credit report.
My name is [Full Name], date of birth [DOB], and the last four digits
of my SIN are [XXXX].
DISPUTED ITEM:
Creditor: [Lender Name]
Account Number: [Full or partial account number]
Description of error: [State exactly what is wrong — e.g., "This account
was paid in full on [date]. The status still shows as 'in collections'
with an outstanding balance of $[X]."]
Requested correction: [State exactly what you want — e.g., "Update status
to 'Paid, $0 balance' and remove the collection notation."]
Enclosed documents:
- [List each document]
I understand you are required to investigate this dispute and provide a
written response. Please send your response and any updated credit report
to the address above.
Sincerely,
[Signature]
[Printed Name]
[Phone Number]
[Email Address]
Enclosures: [List again]
Be specific in every field. Vague dispute letters (“this is wrong”) are harder to investigate and more likely to be returned for clarification. Specific disputes (“the balance on account #XXXX with [Lender] shows $1,200 owing; I paid this in full on March 14, 2025, as shown in the enclosed bank statement”) are actionable immediately.
Step 5: What Happens During the Investigation
Once you submit a dispute, the bureau contacts the creditor that provided the information and requests verification. The creditor has approximately 30 days to respond. If the creditor confirms the information is correct, the bureau keeps it on file and notifies you. If the creditor cannot verify the information or acknowledges the error, the bureau corrects or deletes the entry.
You receive a written response either way. If a correction is made, the bureau provides an updated credit report at no charge. The updated information is also typically communicated to any lender who pulled your report recently, though this varies.
One important nuance: a correction at one bureau does not automatically correct the other. If the same error appears on both Equifax and TransUnion, you need to dispute with both. Some creditors update both when notified by one, but this cannot be relied upon.
Step 6: Disputing Directly with the Creditor
In parallel with or instead of a bureau dispute, you can contact the creditor — the bank, collection agency, or lender — that reported the incorrect information. Write a formal letter to their credit reporting or disputes department, describe the error, attach your evidence, and request they correct the tradeline they report to the bureaus.
A correction made at the creditor level often reaches the bureau faster than a bureau-initiated investigation, because the creditor simply updates their next scheduled data submission rather than responding to an external inquiry. If the creditor agrees the error is theirs, ask for written confirmation and follow up in 30 days to confirm the bureau file has been updated.
Step 7: If Your Dispute Is Rejected
Add a Consumer Statement
Both Equifax and TransUnion allow you to add a consumer statement of up to 100 words to your credit file. The statement appears alongside the disputed item on every credit report pulled in future. It does not remove the entry or change the score, but it gives lenders context — particularly useful when the error is a “he said / she said” situation with a creditor.
A consumer statement should be factual and specific: “Account #XXXX with [Lender] was paid in full on [date]. I have documentary evidence of payment. I contest the outstanding balance shown.” Emotional or vague statements are less useful to a lender reading your file.
Escalate to the FCAC
The Financial Consumer Agency of Canada (FCAC) oversees federally regulated financial institutions — the major banks, federally chartered credit unions, and similar entities. If a bank refused to correct a reporting error it acknowledged, or failed to follow proper dispute procedures, file a complaint at fcac-acfc.gc.ca. The FCAC cannot directly order a score change but can investigate and compel compliance from institutions under its jurisdiction.
Contact Your Provincial Consumer Protection Office
The credit bureaus themselves — Equifax and TransUnion — are regulated at the provincial level under consumer reporting legislation in most provinces. If Equifax or TransUnion failed to investigate properly, failed to respond within required timelines, or refused to correct information that is demonstrably inaccurate, your province’s consumer protection office is the escalation path.
In Ontario, this is Consumer Protection Ontario. In British Columbia, the Consumer Protection BC. In Quebec, the Office de la protection du consommateur. Each province has equivalent legislation — the Consumer Reporting Act or its provincial equivalent — that governs bureau conduct and your rights under it.
How Long Negative Information Stays on File
Even after a successful dispute removes inaccurate entries, accurate negative information has its own removal timeline. The clock runs from the date of the event — not the date you paid the debt or resolved the situation.
| Negative Item | Retention Period |
|---|---|
| Late payment (30, 60, 90 days) | 6–7 years from date of missed payment |
| Collection account | 6–7 years from date account went to collections |
| Consumer proposal | 3 years after completion (Equifax) / 6 years from filing (TransUnion) |
| Bankruptcy | 6–7 years after discharge |
| Court judgment | 6–7 years |
| Hard credit inquiry | 3 years (scoring impact fades after 12 months) |
Accurate negative information cannot be removed through a dispute — only inaccurate information can. If a late payment actually happened, it stays for 6–7 years. A dispute that attempts to remove accurate negative information will be rejected, and repeated frivolous disputes can be noted on your file.
Expected Score Impact of Corrections
The score improvement from a successful dispute depends on the severity of the removed entry and your overall credit profile. The more thin or otherwise clean a file is, the more any single negative item weighs on the score — and therefore the more its removal improves it.
| Correction Made | Typical Score Improvement |
|---|---|
| Collection account removed | +25–100 points |
| Late payment corrected to on-time | +20–50 points |
| Incorrect high balance / low limit corrected | +10–40 points |
| Duplicate tradeline removed | Varies (depends on the entry) |
| Identity theft account removed | +30–100+ points |
Actual impact depends on the overall profile. Improvement is typically seen within one to two reporting cycles after the correction is made.
Credit Repair Companies: Avoid Them
Companies that charge fees to “repair” your credit perform no service that you cannot do yourself for free using the process above. Several red flags identify predatory credit repair services:
They guarantee a specific score increase — which no one can legally guarantee. They charge upfront fees before any service is delivered — which is prohibited under some provincial consumer protection laws. They promise to remove accurate negative information — which is not possible. They suggest creating a new credit identity using a different number — which is identity fraud.
