Key takeaways
- →Equifax and TransUnion each maintain separate files — not two views of one shared database — built from whichever creditors choose to report to each.
- →Not every creditor reports to both bureaus, so one file can show an account the other simply doesn't have.
- →Equifax's Beacon and TransUnion's Empirica are different scoring models, even though both use a familiar 300–900 scale.
- →Canadian mortgage lenders most commonly pull Equifax, though practice varies by lender — worth confirming which bureau a specific lender relies on before a discrepancy becomes a surprise.
It's common for a client to show up with two credit monitoring apps — one pulling Equifax, one pulling TransUnion — showing two different scores, sometimes by a wide margin, and assume one of them must be wrong. Neither necessarily is.
Here's why the two bureaus routinely disagree on the same person, and which one is actually likely to matter for a given mortgage file.
01 · Are Equifax and TransUnion really two entirely separate files?
Yes — each bureau independently collects data from creditors who choose to report to them, and maintains its own file on a given consumer. There's no single shared national credit database behind the scenes reconciling the two; what a bureau knows about someone is limited to what creditors have chosen to furnish to that specific bureau.
02 · Why does one bureau sometimes show an account the other doesn't have at all?
Creditors decide, individually, which bureau or bureaus they report to — some report to both, some to only one, and that choice can also vary by product line within the same lender. A client can have a perfectly real, active account that simply never made it onto one of the two files, which is often the single biggest driver of a large gap between the two.
03 · Do Equifax and TransUnion actually use different scoring models?
Yes — Equifax's Canadian score is commonly referred to as Beacon, and TransUnion's as Empirica, both FICO-derived and both scored on the familiar 300–900 range, but built and weighted independently. Even with identical underlying data, the two models can and do produce different numbers for the same person.
04 · Which bureau do Canadian mortgage lenders actually tend to pull?
Equifax is the bureau most commonly pulled for Canadian mortgage applications, though this varies by lender and isn't a universal rule — some lenders pull both, and some may pull TransUnion depending on their own underwriting setup. It's worth confirming which bureau a specific lender relies on rather than assuming the client's self-monitored score, which may be pulling the other bureau, is the number that will actually be used.
Know which file actually counts
Pull the bureau the lender will actually use — before it's a surprise.
Treadstone's fulfillment associates confirm which bureau each lender relies on before a client's self-monitored score sets the wrong expectation.
05 · When does an Equifax/TransUnion discrepancy actually matter for a live deal?
It matters most when a client's self-reported or app-monitored score, often TransUnion or a third-party estimate, is meaningfully higher than what the lender's actual pull comes back with — setting an expectation that then has to be walked back mid-deal. Pulling the same bureau the lender will use, early, avoids that conversation happening at the worst possible time.
