Key takeaways
- →The single most common explanation is the simplest one: the two pulls came from different bureaus, or different score models, not the same measurement twice.
- →Equifax's Beacon score and TransUnion's Empirica score use different data and different models — they will almost never match exactly, even pulled the same day.
- →New data reporting between pulls — a new balance, a paid-down card, a resolved dispute — explains most of the rest.
- →A genuinely unexplained large swing is worth investigating for an error, but it's the exception, not the first assumption.
A broker pulls credit at pre-approval and again closer to submission, and the client's score has moved — sometimes up, sometimes down, sometimes by more than either of them expected. The instinct is to assume something happened. Usually, something ordinary happened.
Here's the actual list of reasons, roughly in order of how often each one turns out to be the real explanation.
01 · Is the score difference just because it's a different bureau?
This explains more score differences than anything else on this list. Equifax Canada and TransUnion Canada each maintain separate files, built from data furnished by creditors who don't all report to both bureaus — so the underlying data going into the two scores isn't even identical, before the scoring model is applied at all.
02 · Could it be the scoring model itself, not the data?
Equifax's Canadian score is commonly referred to as Beacon; TransUnion's as Empirica — both are FICO-derived models built for the Canadian market, both scored on the same 300–900 scale, but they weight factors differently enough that identical underlying data can still produce different numbers. Lenders may also pull a specialty mortgage-specific score variant rather than the consumer-facing score a client sees on an app, which adds another layer of possible difference between what a client screenshots and what the lender actually sees.
03 · What actually changed on the file between the two pulls?
- →A new balance reported, or an existing one paid down.
- →A new hard inquiry from shopping for another product.
- →A paid or settled account changing status.
- →A dispute resolving one way or the other.
- →Simply the passage of time, adding a few more months of on-time payment history.
Any one of these, alone, is often enough to move a score by a noticeable amount — a client doesn't need a dramatic event to explain a real shift.
04 · When is a score change actually worth digging into?
A swing that's large, unexplained by anything on the checklist above, and moves in a direction that doesn't match the client's recent activity is worth a closer look at the underlying report — not the score alone — to check for a new negative item, an error, or a fraud alert (see our fraud alert article for that specific scenario). Pull the full report, not just the score, before assuming the worst.

05 · How should a broker explain a score change to a client without causing alarm?
Most clients only need to hear that different bureaus and different models produce different numbers by design, not by mistake, and that a modest shift week to week is normal rather than a sign anything is wrong. Reserving genuine concern for a swing that's both large and unexplained keeps the conversation calibrated correctly.
