Canada has two consumer credit bureaus: Equifax Canada and TransUnion Canada. Both maintain a credit file on you, both calculate credit scores, and both report to lenders. They’re not the same, though. Your Equifax score and your TransUnion score can differ by 20-40 points at any given moment because each bureau has slightly different data on you.
This guide explains how Equifax and TransUnion actually differ in Canada, when to prefer one over the other, and why most serious Canadians track both.
The Same Job, Different Inputs
Both Equifax and TransUnion do fundamentally the same thing in Canada:
- Collect credit-account data from Canadian lenders, utilities, and collection agencies
- Maintain a consumer credit file for every Canadian with a borrowing history
- Calculate a credit score on the 300-900 scale
- Sell access to that data (and score) to lenders, landlords, employers, and sometimes insurers
The differences come from which lenders report to which bureau and when. Not every Canadian lender reports to both. A loan that shows on your Equifax file might be missing from your TransUnion file (or vice versa). This is the single biggest reason your scores differ.
Key Differences Between Equifax and TransUnion Canada
Lender Coverage
The major Canadian banks (RBC, TD, Scotiabank, BMO, CIBC, National Bank) report to both bureaus. So do most credit card issuers and major alternative lenders.
The gaps tend to be at the edges:
- Smaller credit unions sometimes report to only one bureau (more commonly Equifax)
- Provincial collection agencies vary
- Some online installment lenders report to only one
- Mortgage lenders generally report to both
- CRA tax debt doesn’t show on either unless it’s been registered as a judgment
If a specific account shows on one bureau but not the other, the bureau that has it usually shows the more accurate picture of that aspect of your credit life.
Score Range and Model
Both bureaus use the 300-900 scale, but they use slightly different scoring models:
- Equifax Canada primarily uses the Equifax Risk Score 2.0 (ERS 2.0) for consumer-facing scores like the one Borrowell shows
- TransUnion Canada uses the TransUnion CreditVision Risk Score for most consumer-facing scores
Lenders may use different scores than what you see on the consumer side. The score a mortgage lender pulls might be a FICO variant or a specialty model used only for mortgages. The score you see on Borrowell isn’t necessarily the same score your bank uses to approve a personal loan.
What Each Bureau Emphasizes
Both bureaus weigh the same five factors, but the exact weights and modelling differ:
- Equifax is sometimes said to weight utilization slightly more heavily
- TransUnion is sometimes said to weight payment history depth (long history of perfect payments) more heavily
In practice, the differences are subtle. Both scores move in roughly the same direction when you change behaviour. A score below 660 on one bureau is rarely above 720 on the other.
Data Update Timing
Bureau updates aren’t simultaneous. Your card issuer might report to Equifax on the 5th of the month and TransUnion on the 20th. If you paid down a card balance on the 10th, your Equifax utilization won’t reflect the lower balance until the next month, while TransUnion will catch it sooner.
This creates short-term score swings between the bureaus that even out over time.
Dispute Process
Both bureaus have similar online dispute processes:
- Submit through their respective consumer portal
- Provide documentation supporting the dispute
- Bureau investigates with the data furnisher (the lender, collection agency, etc.)
- Response typically within 30 days
You have to file disputes separately at each bureau. Fixing an error at Equifax doesn’t automatically fix the same error at TransUnion. Most reporting errors live in both files, so plan to dispute twice.
Which Bureau Do Canadian Lenders Use?
In Canada, most mortgage lenders pull both bureaus (or one of them, depending on internal preference) and use the lower score for the application; they’re conservative. Personal loan and credit-card issuers vary more:
- RBC, TD, Scotia, BMO, CIBC: typically pull Equifax for personal credit decisions, sometimes both for larger applications
- National Bank: Equifax-focused
- Credit unions: mixed; many use Equifax
- Alternative lenders: mixed; depends on the lender’s data partnerships
- Auto-loan financing: typically pulls TransUnion through specialty auto-credit models
- Most landlords: Equifax through tenant-screening services
What this means: for most Canadians, Equifax matters slightly more for major loan applications, while TransUnion can be the differentiator for auto-credit and some specialty products.
Should You Monitor One or Both?
Most Canadians benefit from monitoring both because:
- Identity theft can show up on either bureau first. Catching it sooner limits damage.
- Reporting errors happens on either side. Cross-checking surfaces them.
- You can predict which score a specific lender will pull if you know your numbers on both bureaus.
- It’s free. Borrowell shows Equifax; Credit Karma Canada shows TransUnion. Combined, they’re a free dual-bureau monitor.

When the Scores Differ Significantly
If your Equifax and TransUnion scores differ by more than 40-50 points, something specific is going on:
- A negative item (collections, missed payment, judgment) is reported to one bureau but not the other
- A positive account is reported to one bureau but not the other (often an alternative lender or credit union)
- A merge error has assigned someone else’s data to your file at one bureau
Pull the full reports from both bureaus and compare them. The Government of Canada’s Financial Consumer Agency of Canada credit-report guide walks through how to read each report and what to do when discrepancies arise.
How to Use Both Effectively
A simple monthly habit:
- Week 1: check Equifax via Borrowell or your bank app
- Week 2: check TransUnion via Credit Karma Canada
- Compare: look for any account showing on one but not the other, any difference in reported balance, any negative item only on one side
- Dispute anything that’s clearly an error at the bureau that has it
This habit takes 10 minutes a month and catches reporting issues fast. The Canadians who’ve consistently monitored both for several years are the same Canadians who routinely qualify for prime products without surprises.
Building Your Score on Both Bureaus
If you’re rebuilding from a thin or damaged file, the most effective approach is to use products that report to both bureaus. Most secured cards and major alternative lenders now do.
