Equifax vs. TransUnion Canada: Key Differences You Need to Know

Mar 20, 202619 min read

Ask most Canadians how many credit bureaus operate in Canada and you’ll likely get a blank stare — or a guess of “one.” The reality is that Canada has two major credit bureaus: Equifax Canada and TransUnion Canada. Both collect and maintain credit data on tens of millions of Canadians. Both sell that data to lenders, landlords, and employers. And both assign you a credit score.

But here’s what surprises most people: your credit scores at Equifax and TransUnion are almost certainly different from each other — sometimes by 20, 50, or even 100+ points. The accounts on your reports may differ too. And the lender who pulled your credit last week may have only seen one of those two reports, not both.

If you’re trying to rebuild credit after financial hardship, understanding the differences between these two bureaus isn’t just interesting — it’s essential. The more you know about how each bureau operates, what data they hold on you, and how lenders use them, the better equipped you are to manage your credit strategically.

The Basics: What Are Credit Bureaus and What Do They Do?

Credit bureaus — also called credit reporting agencies (CRAs) — are private companies that collect and organize credit information about consumers. They don’t make lending decisions themselves. Instead, they gather data from lenders who voluntarily submit payment history information, then package that data into credit reports and credit scores that lenders can purchase when evaluating loan applications.

In Canada, both Equifax and TransUnion are for-profit companies that operate under federal and provincial consumer protection legislation. They’re not government agencies, and they’re not advocates for consumers — their primary clients are the lenders and businesses that pay for access to credit data.

Equifax Canada: Overview and Background

Equifax is the older of the two bureaus, with roots going back to 1899 in the United States. Equifax Canada operates as a subsidiary and has maintained credit data on Canadians for decades. It’s headquartered in Canada and operates under Canadian law.

Equifax tends to be the bureau of choice for many of Canada’s largest financial institutions, including several major banks and auto lenders. When a bank says “we checked your credit,” there’s a reasonable chance they checked Equifax.

TransUnion Canada: Overview and Background

TransUnion entered the Canadian market in 1989 when it acquired the credit bureau operations of Trans Canada Credit. Today it’s a major player in Canada’s credit ecosystem, with particular strength among credit card issuers, telecommunications companies, and some financial institutions.

TransUnion has also been more aggressive in the consumer-facing space, with apps, monitoring services, and educational tools. Credit Karma Canada, one of the most popular free credit monitoring apps in Canada, uses TransUnion data.

TransUnion Canada Key Facts

Both Equifax Canada and TransUnion Canada must comply with the federal Personal Information Protection and Electronic Documents Act (PIPEDA) and applicable provincial consumer reporting legislation. This means both are required to give you access to your own data, investigate disputes, and correct genuine errors. Neither bureau is a government agency — they are private corporations subject to regulatory oversight.

Credit Scoring Models: How Each Bureau Calculates Your Score

This is where things get genuinely confusing for most Canadians. Both Equifax and TransUnion use their own proprietary scoring models. The scores are calculated differently, weighted differently, and updated on different schedules. The result: two scores that can diverge significantly even when based on similar underlying data.

The Scoring Scale: Same Range, Different Numbers

Both Canadian bureaus use a score range of 300 to 900. The same general categories apply:

What Factors Go Into Each Score?

Both bureaus assess similar factors, but the weighting differs:

While the general categories look similar, the specific algorithms — how recent activity is weighted, how the type of negative item affects the score, how quickly the score recovers from certain events — differ between the two bureaus. This is why identical real-world credit behaviour can produce different scores at each bureau.

Why Your Scores Differ Between Equifax and TransUnion

If the same information went into both bureaus and both used the same algorithm, your scores would be identical. But neither of those conditions holds true. Here are the main reasons your scores diverge:

Reason 1: Not All Lenders Report to Both Bureaus

Reporting to credit bureaus is voluntary in Canada. Lenders choose which bureau(s) to report to. A credit card company might report to Equifax only. A car dealership might report to TransUnion only. A bank might report to both. The result: your credit reports at each bureau may contain different sets of accounts.

If you have a credit card that only reports to Equifax, it won’t help your TransUnion score — no matter how perfectly you manage it. And if it has a high balance, it won’t hurt your TransUnion score either.

Reason 2: Different Scoring Algorithms

Each bureau uses its own proprietary algorithm. These algorithms assign different weights to different factors, handle edge cases differently, and respond to certain events differently. A bankruptcy might affect your Equifax score more severely than your TransUnion score in a given month, for example.

Reason 3: Different Data Update Schedules

Lenders who do report to both bureaus don’t always update both at the same time. A payment you made this week might appear on one bureau’s report days before it shows on the other. This can cause temporary score discrepancies.

Reason 4: Different Error Rates

Errors exist on credit reports, and an error at one bureau won’t automatically exist at the other. If your Equifax report has a collections account that shouldn’t be there, your TransUnion score may be unaffected — and vice versa.

If your score is significantly higher at one bureau than the other, you can sometimes use this to your advantage. When shopping for loans, ask lenders which bureau they use. If you have a strong Equifax score but a weaker TransUnion score, you may want to prioritize lenders who pull Equifax. This strategy doesn’t work for all loans (especially mortgages, which often check both), but it can matter for personal loans and credit cards.

How to Get Your Free Credit Reports From Each Bureau

Both bureaus are legally required to provide you with a free copy of your credit report upon request. Here’s exactly how to do it from each:

1. Request your Equifax Canada report

   Visit equifax.ca and create an account, or call 1-800-465-7166. You can get a basic free report online. For a complete consumer disclosure (the full report you’re legally entitled to), you may need to request the “Equifax Credit Report” specifically. Mail requests can be sent to Equifax Canada Co., Consumer Relations Department, Box 190 Jean Talon Station, Montreal, QC H1S 2Z2.



2. Request your TransUnion Canada report

   Visit transunion.ca and create an account, or call 1-800-663-9980. TransUnion offers a free Consumer Disclosure online. You can also visit a TransUnion office in person in major Canadian cities for same-day service. Mail requests go to TransUnion Consumer Relations, P.O. Box 338, LCD1, Hamilton, ON L8L 7W2.



3. Verify your identity with both bureaus

   Both bureaus will ask you to confirm your identity. This may include answering questions about your credit history (knowledge-based authentication) or submitting copies of government-issued ID.



4. Review both reports in parallel

   Don’t just glance at each report. Go through them systematically — personal information, account history, collections, public records, and inquiries. Note any differences between the two reports.



5. Track what's on each and what isn't

   Make a list of every account you know you have and check whether it appears on both reports, only one, or neither. Accounts that only appear on one bureau’s report are only affecting that bureau’s score.

Which Lenders Use Equifax vs. TransUnion in Canada?

Lenders don’t publicly disclose which bureau they use. But through aggregated consumer reports and industry knowledge, patterns have emerged. Keep in mind this is general guidance — individual lenders can and do change their bureau preferences:

Before applying for credit, you can ask the lender which bureau they use. Many will tell you. This lets you know which report they’ll see and gives you a chance to review that specific report first for any surprises.

Comparing Report Formats: What Each Bureau Shows

Both bureaus collect similar categories of information, but the presentation and some details differ.

Personal Information

Both bureaus collect your name, date of birth, current and previous addresses, employment information, and SIN. Both may show multiple variations of your name if creditors have reported slight differences. Neither bureau should show your income, bank account balances, or investment information — that data is not part of credit reporting.

Trade Lines (Account History)

This is the most important section. Both bureaus show the same general categories of information per account: creditor name, account type, date opened, credit limit or loan amount, balance, payment status, and payment history. However, the specific presentation varies:

• Equifax displays payment history using a rating system (R1–R9 for revolving accounts, I1–I9 for installment, O1–O9 for open accounts)
• TransUnion uses a similar notation system but the visual layout of the report differs
• Both use “1” to mean current/paid as agreed and higher numbers to indicate delinquency

Collections

Both bureaus show collection accounts but may receive information from different collection agencies. It’s entirely possible for a collection account to appear on one bureau’s report and not the other, depending on which bureau the collection agency reports to.

Public Records

Both bureaus collect bankruptcy and consumer proposal information from public court records. Both should show this information with the same level of accuracy, but verify that discharge dates are correctly recorded on both reports.

Inquiries

Both bureaus distinguish between hard inquiries (initiated by a lender when you apply for credit — these affect your score) and soft inquiries (from you checking your own report, or from pre-approved offer screening — these don’t affect your score). The specific inquiries on each bureau’s report will differ because different lenders use different bureaus.

Credit Monitoring Services: Equifax vs. TransUnion

Both bureaus offer paid monitoring services, and several third-party apps provide free monitoring using data from one of the two bureaus. Here’s a comparison:

For most Canadians — especially those rebuilding credit — the free options (Borrowell and Credit Karma Canada) are sufficient for regular monitoring. Together, they give you access to data from both bureaus at no cost.

By using Borrowell (Equifax data) and Credit Karma Canada (TransUnion data) simultaneously, you can monitor both of your credit files for free. Set up alerts on both apps so you’re notified immediately of any changes. This is especially important if you’ve been a victim of identity theft or are actively rebuilding your credit.

How Lenders Really Use Credit Bureau Data

Understanding what lenders actually see — and how they interpret it — can help you make smarter decisions about managing your credit profile.

Single-Bureau Pulls

Many lenders, especially for smaller loans and credit cards, only pull from one bureau. They see your credit report and score from that single bureau only. If that bureau’s report is stronger (or weaker), it has an outsized impact on your application.

Dual-Bureau Pulls

For larger credit decisions — mortgages, large auto loans, business credit — lenders often pull from both bureaus. When they get two different scores, they typically use the lower of the two scores as the qualifying score. This is critical: if you’re applying for a mortgage and your Equifax score is 680 but your TransUnion score is 610, the lender will likely use 610 for qualification purposes.

Internal Scoring Models

Many larger Canadian financial institutions don’t rely solely on the bureau’s generic score. They purchase raw credit data from the bureau and feed it into their own internal scoring models, which weigh factors specific to their lending criteria and portfolio performance. The number you see on your Borrowell or Credit Karma account may differ substantially from what that bank’s internal model produces.

What Appears Differently Between the Two Reports

Here are the most common types of discrepancies between Equifax and TransUnion reports:

• Missing accounts: Credit cards, loans, or lines of credit that only report to one bureau
• Different balances: Due to different update timings, the balance on the same account may differ by days of transactions
• Different inquiry histories: Lenders who only pull from one bureau appear only on that bureau’s inquiry list
• Different collections: Collection agencies choose which bureau to report to; some use both, some use only one
• Different account statuses: An account status update made to one bureau may take longer to appear at the other

Rebuilding Credit: Which Bureau Matters More?

If you’re actively working to rebuild your credit, you may wonder whether to focus your efforts on improving your Equifax score, your TransUnion score, or both. The answer depends on your specific goals:

If You’re Applying for a Mortgage

Focus on both. Mortgage lenders in Canada routinely check both bureaus. Your goal should be to improve both scores to at least 620, with 680+ being the target for competitive rates.

If You’re Applying for a Credit Card

Research which bureau your target card issuer uses. If you’re applying to Capital One Canada, Credit Karma (TransUnion) data suggests they often use TransUnion. If you’re applying to a bank-issued card, Equifax may be the primary bureau. Improving the right bureau’s score can improve your approval odds.

If You’re Applying for a Car Loan

Auto lenders vary widely. Ask the dealer’s financing department which bureau they use before applying. In Canada, many auto financing companies show a preference for Equifax, but this isn’t universal.

General Rebuilding Strategy

Regardless of which bureau any specific lender uses, the best long-term strategy is to improve both simultaneously by focusing on the underlying behaviours that drive scores at both bureaus:

• Pay every bill on time, every time
• Keep credit card balances below 30% of the limit (below 10% is even better)
• Don’t close old accounts unnecessarily
• Limit hard inquiries to one or two per year
• Add a secured credit card or credit-builder loan that reports to both bureaus

Credit Freezes and Fraud Alerts: How Each Bureau Handles Them

Both bureaus offer fraud alerts and credit freezes, but the process for each differs slightly:

If you’re concerned about identity theft or unauthorized credit applications, you need to place a fraud alert or freeze at BOTH Equifax and TransUnion separately. A freeze at Equifax has no effect on TransUnion, and vice versa.

Understanding Your Rights With Both Bureaus

Your rights with both Equifax Canada and TransUnion Canada are governed by the same federal and provincial legislation:

Conclusion: Know Both Your Credit Profiles

The takeaway from understanding Equifax Canada versus TransUnion Canada isn’t that one is better than the other — it’s that they’re both important, they’re both incomplete pictures on their own, and together they give you the fullest view of how lenders see you.

For Canadians rebuilding their credit, the knowledge that your reports can differ meaningfully between bureaus is both a challenge and an opportunity. A challenge because you have two separate files to maintain and monitor. An opportunity because a lender who uses your stronger bureau may be more accessible than you thought.

Pull both reports today. Use the free monitoring tools available to you. Dispute any errors on either report. And use the knowledge of which bureau your target lenders prefer to apply strategically. Your credit future — at both bureaus — is something you can actively shape.
