Equifax vs. TransUnion: Why Your Car Loan Might Only Show Up on One
People tend to talk about "your credit score" as if it's one number in one place. In Canada there are two of them, held by two competing private companies that don't talk to each other. That single fact explains a long list of otherwise baffling experiences — including the common one where a car loan you've been paying faithfully for a year turns out to be missing from one of your two credit reports.
- Equifax Canada and TransUnion Canada hold entirely separate files. Nothing copies between them.
- Reporting is voluntary — a lender can report to one bureau, both, or neither.
- If your loan reports to only one bureau, only one of your two files is being rebuilt.
- Disputes must be filed separately with each bureau. Fixing one does nothing to the other.
Two companies, two files, no shared pipe
Equifax Canada and TransUnion Canada are consumer reporting agencies — private, competing businesses that collect information from lenders and sell reports back to lenders. They are not government registries, they are not branches of the same organization, and there is no clearinghouse in the middle synchronizing them.
Everything on your credit report got there because a creditor chose to send it. That's the piece most people are missing: reporting is voluntary. A lender decides which bureaus it has a data-furnishing relationship with, and that decision is driven by cost and business preference, not by any obligation to you. Which is why your two files can legitimately tell different stories about the same financial life.
Why your loan might appear on only one
There are a handful of ordinary explanations, and only one of them is a problem:
- The lender only reports to one bureau. The most common reason, and entirely legal. Smaller and regional lenders in particular may maintain a relationship with just one.
- It's too early. Reporting runs on monthly cycles and lenders don't all submit on the same date. An account can take 30 to 60 days to appear, and sometimes shows up on one bureau a cycle before the other.
- A data mismatch. If your name, date of birth, SIN, or address on the loan doesn't match what a bureau has on file, the account can fail to attach to your file — or attach to a partial duplicate file.
- The lender doesn't report at all. The one that matters. Some in-house and "buy here, pay here" arrangements report to neither bureau, meaning years of payments build nothing anywhere.
The reason to care about which explanation applies to you is that three of the four are fixable with a phone call, and you can only make that call if you've looked.
How the two bureaus actually differ
They're more alike than different, but the differences are the ones that trip people up:
| What | Equifax Canada | TransUnion Canada |
|---|---|---|
| Score range | 300–900 | 300–900 |
| Accounts on file | Only what its furnishers send | Only what its furnishers send |
| Scoring model | Its own models, updated over time | Its own models, updated over time |
| Free consumer app commonly tied to it | Borrowell | Credit Karma |
| Disputes | Filed and resolved independently | Filed and resolved independently |
| Report layout and wording | Different labels for the same concepts | Different labels for the same concepts |
General characteristics — products, models, and consumer offerings change over time.
The shared 300–900 range does a lot of quiet damage here, because it implies the numbers are equivalent. They aren't. A 640 at one bureau and a 610 at the other isn't a contradiction to be resolved; it's two different calculations run on two different sets of accounts.
Canadian files also use letter-and-number ratings on individual accounts — an installment loan like a car loan is rated on an I1 to I9 scale, where I1 means paid as agreed. Both bureaus use this convention, so once you know to look for it, you can read your auto loan's standing directly rather than inferring it from the score.
Why this matters more during a rebuild
If you're not actively rebuilding, a single-bureau car loan is a minor inefficiency. If you are, it's a real problem — because the whole point of the loan is to generate installment history, and history that lands on only one file leaves the other exactly as thin as it was.
The consequence shows up later, at the worst time. You spend eighteen months building a payment record, walk into a refinance or a mortgage conversation, and the lender pulls the bureau your loan never reported to. From their side, your file looks unchanged. Nothing you did was wrong; the evidence simply isn't where they're looking.
"My Borrowell score kept climbing and I felt great about it. Then a lender pulled the other bureau and quoted me like I'd done nothing for a year."
What to do about it
This is a short, concrete list, and the whole thing costs nothing:
- ✓Ask before you sign: "Do you report to Equifax, TransUnion, or both — and how often?" Get a specific answer, not a reassurance.
- ✓Pull both reports about 60 days after funding. Not one. Both. This is the single check that catches almost every problem in this article.
- ✓If the account is missing from one, call the lender and ask them to report to both. Many will — the cost to them is small.
- ✓Check that your personal details match across both files. A misspelled name or an old address is a common reason an account fails to attach.
- ✓Dispute errors with each bureau separately. There's no shared queue; two problems need two filings.
- ✓Re-check every six months while rebuilding. Reporting can stop as quietly as it started, particularly if a loan is sold to another servicer.
That last point deserves emphasis. Auto loans are sometimes transferred between servicers, and reporting occasionally lapses in the handover. A six-month rhythm catches it while it's still one missing cycle rather than a year-long gap.
Your access rights in Ontario and Quebec
Ontario. The Consumer Reporting Act gives you the right to see your own consumer report and to dispute inaccurate information in it. If you were declined for financing, you're also entitled to know which reporting agency the lender used — which is genuinely useful information, because it tells you which of your two files is the one being read.
Quebec. Quebec has the stronger regime of the two. Credit assessment agents must provide residents with a free credit report and a free credit score on request, and Quebec residents can place a security freeze on their file, which blocks new credit applications from being processed against it. If you suspect an error or fraud is affecting your file, that's a tool Ontario residents don't have in the same form.
In both provinces, checking your own report is a soft inquiry and has no effect on your score. There is no reason to check less often than you'd like.
If you're partway through a rebuild, the six-month check described above fits neatly into the step-by-step subprime-to-prime plan. And if your loan turns out to report nowhere at all, the piece on credit-builder car loans covers what to ask for next time.
Want a lender that reports to both bureaus?

Frequently asked questions
Why does my car loan only show on one credit bureau?
Because reporting is voluntary and separate. Equifax Canada and TransUnion Canada are competing private companies, and lenders choose which ones to report to — some report to both, some to one, and a few don't report at all. There's no rule requiring a lender to report everywhere, and no mechanism that copies an account from one bureau to the other.
Which credit bureau do Canadian car dealerships use?
It varies by lender, and often by region and product. Some auto lenders pull Equifax, others TransUnion, and some pull both for higher-risk files. This is why the score you were quoted at one dealership can differ from another's on the same day — they may not be looking at the same file at all.
Can my Equifax and TransUnion scores be different?
Yes, and a gap is normal. The two bureaus may hold different accounts, receive updates on different dates, and use different scoring models. Both use a 300 to 900 range in Canada, but that shared range doesn't make the numbers interchangeable. A meaningful difference usually means one file is missing an account the other has.
Do I have to dispute an error with both Equifax and TransUnion?
Yes. The bureaus don't share dispute outcomes, so correcting an error at Equifax does nothing to your TransUnion file. If an inaccurate item appears on both reports, you need to file two separate disputes and follow up on each one independently.
How do I make sure my car loan reports to both bureaus?
Ask the lender before signing which bureaus they report to and how often, then verify it yourself roughly 60 days after funding by pulling both reports. If the account is missing from one, contact the lender and ask them to add it — many will, since reporting to both costs them little. If they won't, at least you know which file is being built and can plan around it.
