Phone Numbers

Mailing Addresses

Online Access Points

Consumer feedback consistently shows that the best times to call TransUnion Canada are mid-week (Tuesday, Wednesday, and Thursday) between 10:30 AM and 1:30 PM Eastern Time. Monday mornings are typically the busiest, as people who discovered issues over the weekend call first thing. Friday afternoons can also be busy as people try to resolve issues before the weekend. If you can, avoid calling on the first and last business days of the month, as these tend to have higher call volumes.

How to Get Your Free Credit Report From TransUnion Canada

Every Canadian has the legal right to receive a free copy of their TransUnion credit report. TransUnion offers multiple methods to access your report, each with different advantages.

1. Online Through TransUnion's Website

   Visit transunion.ca and create a consumer account. You will need to verify your identity by answering security questions based on information in your credit file. Once verified, you can view your credit report immediately. The online report is comprehensive and includes your credit history, inquiries, and public records. Note that the free version may not include your credit score.



2. Through Credit Karma Canada

   Credit Karma Canada (creditkarma.ca) provides free access to your TransUnion credit report and score. The service is supported by advertising and product recommendations, but the credit information is genuine TransUnion data. You can check your score and report as often as you like without affecting your credit. This is one of the easiest ways to monitor your TransUnion credit profile on an ongoing basis.



3. By Mail

   Download the credit report request form from transunion.ca or write a letter requesting your report. Include photocopies of two forms of identification (one government-issued photo ID and one proof of address). Mail your request to: TransUnion Consumer Relations, P.O. Box 338, LCD1, Hamilton, Ontario L8L 7W2. Allow 5 to 10 business days for processing after receipt.



4. By Phone

   Call 1-800-663-9980 and follow the automated prompts to request a credit report by mail. You will need to verify your identity with personal information. The report will be sent to your address on file within 5 to 10 business days.

Identity Verification Requirements

If you are unable to verify your identity through TransUnion’s online system, do not worry — this is common and does not mean anything is wrong. The security questions are based on information in your credit file, and sometimes the questions reference old addresses or accounts you may not remember. If online verification fails, simply request your report by mail with copies of your identification documents. This is actually a security feature working as intended.

The TransUnion Dispute Process: Step by Step

Finding an error on your TransUnion credit report can be stressful, but the dispute process is straightforward if you follow the right steps. TransUnion is required by law to investigate your dispute and respond within 30 days.

What You Can Dispute

You can dispute any information on your TransUnion credit report that you believe is inaccurate, incomplete, or outdated. Common reasons for disputes include:

Online Dispute Process

1. Log In to Your TransUnion Account

   Go to transunion.ca and log in to your consumer account. If you do not have an account, you will need to create one and verify your identity. Navigate to your credit report section.



2. Select the Item to Dispute

   Review your credit report and identify the specific item you want to dispute. Click on the item and select the dispute or challenge option. TransUnion’s online system allows you to dispute individual accounts, inquiries, and public record items.



3. Provide Your Explanation

   Select the reason for your dispute from the provided categories and add a detailed explanation of why the information is inaccurate. Be specific — include dates, amounts, and reference numbers where applicable.



4. Upload Supporting Documents

   TransUnion’s online dispute system allows you to upload supporting documents in common formats like PDF and JPEG. Upload copies of any evidence that supports your dispute, such as payment receipts, creditor correspondence, or bank statements.



5. Submit and Track

   After reviewing your dispute, submit it and note the confirmation number provided. You can track the status of your dispute by logging back into your account. TransUnion will update you on the progress, and you will receive the results within 30 days.

Mail-In Dispute Process

For complex disputes or situations requiring extensive documentation, mailing your dispute provides the strongest paper trail. Write a detailed dispute letter including:

Your full legal name, current address, date of birth, and last three digits of your SIN. A clear description of each error, including the creditor name, account number (last four digits), what the report currently shows, and what the correct information should be. An explanation of why the information is wrong. A list of all enclosed supporting documents.

Mail your dispute to: TransUnion Consumer Relations, P.O. Box 338, LCD1, Hamilton, Ontario L8L 7W2

Use Canada Post Registered Mail or Xpresspost to ensure you have proof of delivery. Keep copies of everything you send.

TransUnion Fraud Department: Protecting Your Identity

Identity theft is one of the fastest-growing crimes in Canada, and TransUnion’s fraud department is a critical resource if you suspect your identity has been compromised. Here is how to access their fraud services and what protections are available.

Placing a Fraud Alert

If you suspect you are a victim of identity theft, the first step is to place a fraud alert on your TransUnion credit file. A fraud alert notifies creditors that your identity may have been compromised and that they should take additional steps to verify your identity before opening new accounts.

1. Call TransUnion Immediately

   Call 1-800-663-9980 and select the fraud option from the menu. A representative will assist you in placing a fraud alert on your credit file. Have your personal information ready for identity verification. The fraud alert takes effect immediately once placed.



2. Request Your Credit Report

   While on the phone, request a copy of your credit report so you can review it for any fraudulent activity. The representative can walk you through the report over the phone or send you a copy by mail.



3. Identify All Fraudulent Activity

   Review every section of your credit report for unauthorized activity. Look for accounts you did not open, inquiries you did not authorize, addresses where you have never lived, and employment information that is not yours. Make a list of everything that appears fraudulent.



4. File a Formal Identity Theft Report

   TransUnion may ask you to complete a formal identity theft declaration. This document states that you are a victim of identity theft and identifies the specific fraudulent items on your report. Complete and return this document promptly.



5. File Police and Anti-Fraud Reports

   Report the identity theft to your local police and to the Canadian Anti-Fraud Centre at 1-888-495-8501. Obtain report numbers for both, as TransUnion and creditors may request them as part of the investigation.



6. Contact Equifax as Well

   Remember to also place a fraud alert with Equifax (1-800-465-7166). The two bureaus do not share fraud alerts, so you must contact each one separately to ensure full protection.

If you discover that your identity has been stolen, do not wait even a single day to contact TransUnion and Equifax. Identity thieves can open new accounts, take out loans, and accumulate charges in your name within hours. The sooner you place fraud alerts and begin the investigation, the less damage the thief can cause and the easier it will be to clean up your credit report.

Types of Protection Available

Understanding the TransUnion Online Portal

TransUnion’s online portal at transunion.ca provides consumers with a range of self-service tools that can save time compared to calling or mailing. Here is a detailed look at what you can do online.

Creating Your Account

To access TransUnion’s online services, you need to create a consumer account. Visit transunion.ca and click on the option to sign up or register. You will be asked to provide your personal information including your full name, date of birth, address, and Social Insurance Number. TransUnion will then ask you to answer several security questions based on information in your credit file. If you answer correctly, your account will be activated immediately.

Online Dashboard Features

TransUnion Direct is the bureau’s paid monitoring service offering real-time alerts, unlimited report access, and identity theft insurance. However, before subscribing, consider the free alternatives. Credit Karma Canada provides free access to your TransUnion credit score and report with basic monitoring. Many Canadian banks also offer free credit score access through their apps. The paid service is most valuable for people who have experienced identity theft, are actively rebuilding credit, or want the most comprehensive monitoring available.

TransUnion Phone Hours and Navigation Tips

Getting through to the right department at TransUnion can take time if you do not know the system. Here are detailed tips for navigating their phone system efficiently.

Phone System Navigation Guide

When you call 1-800-663-9980, you will encounter an automated phone system (IVR). Here is what to expect:

The system will first ask you to select your language (English or French). Then you will be presented with options for different services. The exact menu options may change periodically, but generally you can expect options for requesting a credit report, filing a dispute, fraud alerts, account inquiries, and speaking with a representative.

1. Listen to All Options First

   Do not press a button at the first prompt you hear. Listen to all available options before selecting one. The option you need may not be the first one listed, and selecting the wrong option can send you to the wrong department, adding time to your call.



2. Have Your Information Ready

   Before calling, have the following information at hand: your full legal name as it appears on your credit report, your current address, your date of birth, your Social Insurance Number (you may not need to provide the full number, but have it available), and if disputing, the specific details of the items you want to dispute.



3. Ask for a Direct Extension

   Once you reach a representative, ask if there is a direct extension or callback number for the department you are dealing with. This can save significant time if you need to call back. Not all departments have direct lines, but it does not hurt to ask.



4. Request a Reference Number

   For every call, ask for a reference number or case number. Write it down along with the date, time, and name of the representative. This information is crucial for follow-up calls and escalations.

Average Wait Times

TransUnion for Businesses

If you are a business owner, landlord, or organization that needs to access credit data, TransUnion offers a range of business services. Here is how to access them.

Setting up a TransUnion business account typically requires a formal application process, business registration documentation, and may involve a site visit or verification call depending on the type of data you want to access. Businesses that want to pull consumer credit reports must demonstrate a permissible purpose under applicable privacy legislation. Contact the business solutions line at 1-855-729-2889 to start the application process.

Complaint Escalation: When Things Go Wrong

If you are unable to resolve an issue with TransUnion through normal consumer service channels, there is a structured escalation process you can follow. Each level of escalation increases pressure on TransUnion to address your concern.

1. Level 1: Customer Service Representative

   Your first point of contact is the regular customer service team at 1-800-663-9980. Explain your issue clearly and request a resolution. If the representative cannot help, ask to be transferred to a supervisor.



2. Level 2: Supervisor or Team Lead

   A supervisor or team lead has more authority to resolve complex issues, authorize exceptions, or expedite investigations. Explain your situation, reference your previous contacts and case numbers, and clearly state what resolution you are seeking.



3. Level 3: Formal Written Complaint

   If phone escalation does not work, submit a formal written complaint. Address your letter to the Consumer Relations Manager at TransUnion’s Hamilton office. Include a complete timeline of all previous contacts, copies of relevant documentation, and a clear statement of the issue and desired resolution. Send via registered mail.



4. Level 4: Executive Escalation

   If the formal complaint does not produce results, write to TransUnion’s corporate office at 3115 Harvester Road, Suite 201, Burlington, Ontario L7N 3N8. Address your letter to the Vice President of Consumer Relations or the General Manager. Executive-level complaints typically receive faster, more thorough attention.



5. Level 5: External Regulatory Complaints

   If all internal channels fail, file complaints with external regulatory bodies. Your options include the Office of the Privacy Commissioner of Canada, your provincial consumer protection office, and the Financial Consumer Agency of Canada (if the issue involves a federally regulated financial institution).

External Regulatory Contacts

Understanding Your TransUnion Credit Report

Once you have obtained your credit report, understanding its contents is essential. TransUnion organizes their reports into several key sections.

TransUnion Canada vs. TransUnion USA

For Canadians who have lived in or have connections to the United States, it is important to understand that TransUnion Canada and TransUnion USA are separate operations with separate databases.

Your Canadian credit history does not transfer to the United States, and your US credit history does not transfer to Canada. If you move between countries, you effectively start with no credit history at the new country’s bureaus. However, some lenders have programs for newcomers, and certain credit card companies like American Express may consider your credit history from another country through their Global Transfer program.

Special Services and Accessibility

TransUnion Canada offers several special services and accessibility features to ensure all Canadians can access their credit information.

Bilingual Services

All TransUnion consumer services are available in English and French. When calling 1-800-663-9980, you will be prompted to select your preferred language. Quebec residents can also call the dedicated Quebec line at 1-877-713-3393 for service in French. Written correspondence is accepted in both languages, and reports can be provided in your preferred language.

Accessibility

TransUnion works to make their services accessible to all Canadians. Consumers who are deaf or hard of hearing can access TransUnion through TTY relay services provided by their telecommunications provider. Credit reports can be provided in alternative formats upon request. If you require accommodation to access TransUnion’s services, call the main consumer line and explain your needs to a representative.

Deceased Consumer Reports

If you are the executor or administrator of a deceased person’s estate and need to access their TransUnion credit report, you can do so by providing a copy of the death certificate, letters of administration or probate, and your own government-issued photo ID. Mail these documents along with your request to the Hamilton consumer relations address. This process helps protect the deceased person’s identity from fraud and helps executors manage estate obligations.
