TransUnion vs Equifax Canada: Which Credit Bureau Matters More? (2026)

Last week I checked my Borrowell app and it told me my Equifax score was 820. Out of curiosity, I opened Credit Karma five minutes later. TransUnion said 794. Same person. Same credit cards. Same mortgage. 26-point gap.

If you’ve ever stared at two different scores and wondered which one is “real,” you’re asking the wrong question. The real question is: which bureau will the lender pull when you actually apply for something?

I went down this rabbit hole when I was getting my mortgage in 2024 and almost dragged my whole approval into a ditch over it. Let me save you the research.

Why does Canada have two credit bureaus anyway?

Canada has two credit bureaus — Equifax Canada and TransUnion Canada — because no law forces lenders to use one. Both are private companies that collect repayment data from banks, credit card issuers, and collection agencies. Lenders pick whichever they have a contract with, and most banks pull from one as a primary and the other as a secondary check.

Equifax has been in Canada longer (since 1988) and has historically had wider coverage, especially with the Big Six banks. TransUnion arrived later but caught up fast and now dominates with newer fintech lenders, telecom companies, and some auto lenders.

The result is messy on purpose. There’s no “national” Canadian credit score the way you have a single SIN. There are two parallel files, two different scores, two different sets of mistakes that can hurt you.

Which credit bureau do Canadian lenders actually pull from?

In Canada, most major banks (RBC, TD, Scotiabank, BMO, CIBC, National Bank) lean on Equifax as their primary bureau, while telecom companies, auto lenders, and fintech apps often start with TransUnion. Mortgage lenders frequently pull both. There is no universal rule. Every lender chooses based on their internal contract.

Here’s the rough lay of the land as of May 2026, based on my own credit pulls and what I see in my day job:

Lender type	Primary bureau (most common)	Notes
Big Six banks (mortgages, lines of credit)	Equifax	TD and Scotia have been pulling both for mortgages
Credit cards from Big Six	Equifax	Some pull TransUnion as a backup
Auto loans / leasing	TransUnion	Manufacturer-financed leases (Toyota Financial, Honda) often use TU
Fintech (KOHO, Neo, Wealthsimple)	Mix of both	Newer apps lean TransUnion
Telecoms (Bell, Rogers, Telus)	TransUnion	Why a missed phone bill shows up on TU first
Landlords (private credit checks)	Either, depends on screening service	Equifax slightly more common in Ontario
Mortgage brokers (private lenders)	Both	They literally pull both and use the middle / lower

When I applied for my CIBC Costco Mastercard, only Equifax got hit with a hard inquiry. When my Scotia credit line was approved, same. Equifax only. But when my wife (at the time) signed up for a Bell phone plan, the credit check landed on TransUnion. Different bureaus, different inquiry footprints, different scores reacting in different directions.

Why are my Equifax and TransUnion scores different?

Your Equifax and TransUnion scores in Canada are different because the two bureaus use different data, different scoring models, and different update timelines. Each lender reports to one or both bureaus on their own schedule, so a balance paid on June 1 might show on Equifax by June 5 and on TransUnion by June 15. Both bureaus also use slightly different versions of the FICO and VantageScore models.

There are three main reasons the numbers diverge:

1. Reporting differences. Not every lender reports to both bureaus. My CIBC Costco Mastercard reports to Equifax monthly but only sends data to TransUnion every other month. So a payment I make on the 5th might bump my Equifax score before TransUnion even sees it.

2. Scoring model differences. Equifax Canada mostly uses ERS 2.0 (an Equifax-built model) for its consumer-facing score on Borrowell, while TransUnion uses VantageScore 3.0 on Credit Karma Canada. The lender pulling your file can request a different model entirely, including FICO 8 or FICO 9, so the score you see in an app might not be the score the bank sees.

3. Inquiry counting. Both bureaus count hard inquiries, but only the bureau that was pulled records that specific inquiry. When CityBank pulled my Equifax for a fridge financing application during my home purchase (and then declined me three weeks later), only my Equifax score dropped 20 points. My TransUnion stayed flat. The same lender pulled it for a follow-up check weeks later.

A 20–40 point gap between bureaus is normal. A gap above 60 points usually means there’s a reporting error on one of them.

Can errors show up on one bureau but not the other?

Yes. Credit report errors in Canada often appear on one bureau and not the other, because lenders and collection agencies sometimes report to only one. A missed payment, a fraudulent account, or an outdated address can sit on your TransUnion file for months while Equifax stays clean. This is exactly why monitoring both is worth your time.

I caught a real one through Credit Karma in 2023. A telecom partner had signed me up for a “free” SIM card promotion, but it actually opened a small credit account that I was supposed to be paying for. I never got a bill, never got a notice. Credit Karma pinged me about a new account on my TransUnion file. I checked my Borrowell app. Equifax had no record of it yet. The account would have eventually shown up on both, but the head start saved me.

If I’d only used Borrowell, I would have caught it weeks later, possibly after a missed payment had already been reported. The lesson: free monitoring on one bureau is good, free monitoring on both is much better, and there’s no reason not to do both since both are free.

When you find a discrepancy, you have to dispute it with each bureau separately. Equifax won’t fix something on TransUnion’s file and vice versa. I walk through the exact dispute process in the free dispute letter template guide. The same letter works for both, but you mail (or upload) it to each bureau independently.

Should I monitor both bureaus or just one?

You should monitor both Equifax and TransUnion in Canada because errors, fraud, and lender reporting can show up on one bureau weeks before the other. The good news: you can monitor both for free, with no credit card required, using two separate apps. There’s no real downside to checking both, only an upside in catching mistakes faster.

Monitoring just one means you’re flying half-blind. If a fraudulent account opens on the bureau you’re not watching, you might find out only when a collection agency calls, six months later, after your score has already cratered.

I check both apps on the first of every month. Takes me 90 seconds total. Both apps refresh weekly and ping you when something changes. There is genuinely no reason to pick one over the other when both are free.

Which free monitoring tool wins — Borrowell or Credit Karma Canada?

In Canada, Borrowell pulls from Equifax and Credit Karma Canada pulls from TransUnion, so they’re not really competitors, they’re complements. If you can only pick one, pick the bureau your most recent lender pulled from. If you applied for a Big Six mortgage or credit card recently, go with Borrowell (Equifax). If you got financed for a car or a new phone plan, go with Credit Karma (TransUnion).

I’ve been using both since 2023. Some honest observations:

Borrowell has cleaner UX, better email digests, and the mortgage rate comparisons actually update in real time. The downside is the affiliate offers (“you’re pre-approved for this card!”) are aggressive. I ignore them. Score updates weekly.

Credit Karma Canada has a more functional credit report viewer. You can see the actual line-item history per account. The downside is that the score model (VantageScore 3.0) tends to lag behind real lender pulls by 5–15 points. Updates weekly.

I break down the side-by-side in Borrowell vs Credit Karma Canada if you want the full breakdown. The short version: install both, set them both to send you monthly notifications, and stop worrying about which is “more accurate.” Neither is the score your bank actually sees.

What’s the smartest way to use both bureaus together?

The smartest approach in Canada is to treat your two free apps as a fraud-detection system, not a score chase. Check both monthly for new accounts and inquiries you don’t recognize. When you’re about to apply for a major loan, pull both reports directly from Equifax.ca and TransUnion.ca for a more detailed view than the apps offer. And accept that the number on your screen is not what the lender will see.

Here’s what I actually do, on a calendar:

• First of every month: open Borrowell and Credit Karma side by side. Scan the account list. Make sure the inquiry list matches what I remember authorizing.
• Quarterly: pull a full report directly from Equifax Canada (free under PIPEDA — you can request a paper copy or use their consumer portal). Same with TransUnion.
• 60 days before a major loan: pull both, dispute any errors, pay down balances to get utilization under 10% on every card, and stop applying for new credit.
• After a hard inquiry: check whichever bureau was hit, confirm the inquiry is logged correctly, and avoid further applications for at least 6 months.

The mistake I made in 2024 was applying for fridge financing while I was already in mortgage approval. The retailer pulled Equifax. My score dropped 20 points overnight, and even though my mortgage was approved, the broker had to re-run the numbers. Could have been worse. I had a buffer. If you’re sitting at 660 trying to qualify, that 20-point drop is the difference between approval and denial. Read more in the hard inquiries removal guide.

So which bureau actually matters more in Canada?

For most Canadians applying for a mortgage or credit card with a Big Six bank, Equifax matters more. It’s what your lender will pull first. For auto loans, telecom contracts, and newer fintech apps, TransUnion is often the deciding bureau. For your day-to-day score-watching, both matter equally because errors and fraud move between them at different speeds.

What I’d tell my 2022 self, freshly off the plane in Montreal with a Borrowell score of zero: don’t get attached to either number. The score you see in the app is a snapshot of one bureau’s view of you on the day they updated. The score that matters is the one your next lender pulls, on the day they pull it, using the model they happen to subscribe to. There is no single “Canadian credit score.” There’s only your behaviour over time, reported to two bureaus, scored by half a dozen models, and seen by hundreds of lenders who each have their own weighting.

Pay your bills on time. Keep utilization under 30% (under 10% if you want every point you can get). Don’t open three accounts in one month. Watch both bureaus. That’s the whole game.
