Equifax vs. TransUnion: What’s the Difference

Equifax and TransUnion often show different scores for the same person. Here’s why, and which one actually matters when you apply for credit.

Equifax vs. TransUnion: What’s the Difference

Canada has two credit bureaus, Equifax and TransUnion, and neither is a government agency. Both are private companies that collect information from lenders, landlords, and collection agencies, then use it to generate a credit report and a score for almost every adult in the country.

If you’ve ever pulled your score from both and gotten two different numbers, you’re not imagining it. That’s expected, and it doesn’t mean one of them is wrong.

Why they don’t match

Lenders choose which bureau, or bureaus, they report to. Some report to both. Some report to only one. A credit card issuer might update Equifax every month but only send updates to TransUnion quarterly, or not at all. Over time, this creates two files on you that overlap but aren’t identical.

Each bureau also uses its own scoring model. Even with identical information, the math behind the number isn’t the same, so a small difference in score is normal even when your file is basically the same at both.

Does it matter which one a lender uses?

Yes, but you usually don’t get to choose. When you apply for a mortgage, credit card, or loan, the lender picks which bureau (or both) to pull. Banks and larger lenders often check both. Some smaller lenders or landlords only use one.

This is part of why it’s worth checking your report at both bureaus rather than assuming one snapshot tells the whole story. An error sitting only on one file, like an account that isn’t actually yours, could be dragging down your score at that bureau without you knowing.

What’s actually in each report

Beyond the score itself, your report includes:

  • Personal identifying information
  • A list of your credit accounts and their status
  • Payment history for each account
  • Hard inquiries from the past two years
  • Any collections, bankruptcies, or public records

Both bureaus are legally required to give you free access to your own report on request, separate from any paid “credit monitoring” product they may try to upsell you on.

How to check both, for free

You can request your report directly from Equifax Canada and TransUnion Canada without paying. This is different from many of the score-checking apps and bank dashboards, which usually pull from only one bureau and may show a slightly simplified version of the score rather than the exact one a lender would see.

For anyone actively trying to fix an error, apply for a major loan, or just get a fuller picture, checking both is the more complete approach.

The bottom line

Neither bureau is “the real one.” They’re two separate, competing databases tracking overlapping but not identical information about your credit behaviour. The differences in score you see between them are a normal side effect of how lenders report, not a sign that something’s broken.

If your goal is simply to build or maintain good credit, the habits that help, paying on time and keeping balances low, improve your standing at both bureaus at once. You don’t need to manage them separately; you need to manage your accounts well, and the reporting takes care of itself.

FAQ

It varies by lender. Larger banks often pull both. Smaller lenders and landlords may only check one, so there’s no universal answer.

No. Errors need to be disputed separately with each bureau, since they maintain independent files.

Neither is more accurate. They reflect different data and different formulas, both valid, just not identical.
