TransUnion Credit Score Guide for Canada
Loading article…
Understand your TransUnion credit score in Canada, from how it’s calculated to why it might differ from your Equifax score – and what you can do to improve it.
What Is a TransUnion Credit Score?
A TransUnion credit score is a three-digit number between 300 and 900 that represents how likely you are to repay debts on time. TransUnion Canada, one of the two major credit bureaus in Canada, calculates this score based on your credit history.
Lenders use your TransUnion score to assess risk when you apply for one of the best credit cards in Canada, mortgages, loans, or lines of credit. A higher score could help you qualify for better interest rates and higher credit limits.
For more on monitoring your file, see our guides on how to get a free credit score, how to check your credit score, and whether checking lowers it. TransUnion collects information from banks, credit card issuers, lenders, and collection agencies. They track how you manage credit accounts, whether you pay bills on time, and how much debt you carry relative to your limits.
Your TransUnion score updates regularly as creditors report new information. This means your score can improve or decline based on your recent financial behaviour.
How TransUnion Calculates Your Score
TransUnion uses several factors to calculate your credit score. While the exact formula remains proprietary, the bureau weighs five core elements that reflect your credit behaviour.
| Factor | Weight | What It Measures |
|---|---|---|
| Payment History | 35% | Whether you pay bills on time; late payments lower your score |
| Credit Utilization | 30% | How much of your available credit you use; keep below 30% |
| Length of Credit History | 15% | How long your accounts have been open; older accounts help |
| Credit Mix | 10% | Types of credit (cards, loans, mortgages); variety can help |
| New Credit Inquiries | 10% | Recent applications; multiple inquiries in short periods may hurt |
Payment history carries the most weight. Missing even one payment by 30 days or more can drop your score by 60 to 110 points, depending on your overall credit profile.
Credit utilization is the second-largest factor. If you have a credit card with a $5,000 limit and carry a $3,500 balance, your utilization is 70 per cent. TransUnion prefers to see utilization below 30 per cent, and ideally below 10 per cent.
Length of credit history rewards stability. Keeping older accounts open – even if you rarely use them – can strengthen this factor.
Credit mix reflects diversity. Having both revolving credit (credit cards, lines of credit) and instalment credit (car loans, personal loans) demonstrates you can manage different types of debt.
New credit inquiries occur when you apply for credit. Too many applications in a short period may signal financial stress to lenders.
TransUnion Score Ranges in Canada
TransUnion scores range from 300 to 900. Lenders use these ranges to categorize borrowers and set lending terms. Rates and terms may vary by financial institution.
| Score Range | Rating | What It Means |
|---|---|---|
| 760-900 | Excellent | Best rates on mortgages, loans, and credit cards; highest approval odds |
| 725-759 | Very Good | Access to most premium credit products with competitive rates |
| 660-724 | Good | Approved for most credit products; reasonable interest rates |
| 560-659 | Fair | May be approved with higher interest rates or stricter conditions |
| 300-559 | Poor | Difficulty getting approved; may need secured products or guarantors |
Most Canadian lenders look for a score of at least 660 to approve standard credit products. For an insured mortgage, CMHC requires at least one borrower to have a minimum score of 600 (checked October 27, 2026); lenders set their own thresholds and usually reserve their best rates for higher scores.
Borrowell’s 2023 Credit Report put the average Canadian credit score at approximately 672 at the time. This provides a useful benchmark for where you stand relative to other Canadians.
If your score falls below 660, you may still qualify for credit, but you could face higher interest rates or additional requirements such as a larger down payment or a co-signer.
TransUnion vs Equifax in Canada
Canada has two major credit bureaus: TransUnion and Equifax. Both track your credit activity, but they operate independently and may hold slightly different information about you.
Not all creditors report to both bureaus. Some financial institutions report only to TransUnion, others only to Equifax, and many report to both. This means your credit file at each bureau might contain different accounts or payment records.
The scoring models used by TransUnion and Equifax are similar but not identical. Both use the same five core factors, but they may weigh certain elements differently or apply proprietary adjustments.
As a result, your TransUnion score and your Equifax score can differ by 10 to 50 points or more. This is normal and does not indicate an error.
Lenders may pull your credit report from one bureau or both. When you apply for a mortgage, for example, the lender might check both scores and use the lower one to make their decision.
How to Check Your TransUnion Score
You can check your TransUnion credit score for free without affecting your credit rating. This is called a “soft inquiry” and has no impact on your score.
- Credit Karma Canada: shows your TransUnion credit score for free, with a breakdown of the factors that affect it.
- Banking apps: TD, BMO and other banks offer free access to your TransUnion score in their mobile apps, often through the TransUnion CreditView Dashboard.
- TransUnion directly: you can view your credit report (Consumer Disclosure) online for free, or ask for a free copy by mail by calling 1-800-663-9980. The free version includes a score only if you live in Quebec or Ontario.
- Paid services: elsewhere, TransUnion sells a monitoring service that includes your score and alerts.
Checking your own score does not hurt your credit. Only hard inquiries – when a lender pulls your report to make a lending decision – can temporarily lower your score by a few points.
Monitoring your TransUnion score regularly helps you spot errors, track your progress, and catch potential fraud early. If you notice accounts you don’t recognize or incorrect late payments, you can dispute them with TransUnion.
Ways to Improve Your TransUnion Score
Improving your TransUnion credit score takes time, but the actions you take today can lead to measurable gains within three to six months. Focus on the factors that carry the most weight.
- Pay every bill on time: Set up automatic payments or reminders to ensure you never miss a due date, since payment history accounts for 35 per cent of your score.
- Lower your credit utilization: Pay down balances to keep your utilization below 30 per cent of your total credit limit, or request a credit limit increase without increasing spending.
- Keep old accounts open: Even if you rarely use a credit card, keeping it open lengthens your average account age and supports your credit history.
- Limit new credit applications: Apply for new credit only when necessary, and try to space out applications by at least six months to minimize inquiries.
- Review your credit report for errors: Check your TransUnion report annually and dispute any inaccuracies, such as accounts you don’t recognize or payments marked late by mistake.
- Diversify your credit mix: If you only have credit cards, adding an instalment loan (such as a small personal loan) can demonstrate you can manage different types of credit responsibly.
According to the Government of Canada, maintaining a debt-to-credit ratio of 35 per cent or below on credit cards, loans, and lines of credit is recommended. Keeping it even lower – around 10 per cent – can further boost your score.
If you’re rebuilding credit or starting from scratch, consider a secured credit card. These cards require a refundable deposit and report to TransUnion, helping you establish or repair your credit history.

Bottom Line
Your TransUnion credit score is a vital component of your financial health in Canada. Understanding how it’s calculated – with payment history and credit utilization as the top factors – gives you a clear roadmap for improvement. Because TransUnion and Equifax operate independently, your scores may differ, so monitoring both bureaus helps you see the complete picture. Taking consistent action to pay bills on time, reduce balances, and avoid unnecessary credit applications can raise your score and unlock better lending terms. Whether you’re applying for a mortgage, renting an apartment, or securing a new credit card, a strong TransUnion score opens doors.
