Your credit score in Canada isn’t a mystery. It’s a math equation. Equifax and TransUnion both calculate scores using the same five-factor framework borrowed from the FICO and VantageScore models. Once you know what those factors are and how heavily each one counts, the path to a better score gets a lot clearer.
This guide breaks down each of the five factors that affect your Canadian credit score, the weight each one carries, and the concrete habits that move them in your favour.
The Big Picture: Canadian Credit Scores
Both Canadian credit bureaus, Equifax Canada and TransUnion Canada, score consumers on a 300 to 900 scale. Most lenders treat the ranges roughly the same way:
| Score Range | Rating | What It Means |
|---|---|---|
| 760 to 900 | Excellent | Lowest rates, easiest approval |
| 725 to 759 | Very good | Strong approval odds, near-best rates |
| 660 to 724 | Good | Most prime-bank products are open |
| 560 to 659 | Fair / subprime | Banks usually decline; alternative lenders |
| 300 to 559 | Poor | Bad credit; rebuild needed |
Equifax and TransUnion sometimes give you slightly different scores. That’s because not every lender reports to both bureaus, and reporting timing differs by a few weeks. Same data inputs, slightly different snapshots.
Now let’s break down the inputs.
What Affects Your Credit Score in Canada: the Five Factors
| Factor | Approximate Weight | What It Measures |
|---|---|---|
| Payment history | ~35% | Whether you pay on time |
| Credit utilization | ~30% | How much of your available credit you use |
| Length of credit history | ~15% | How long you’ve had credit |
| Credit mix | ~10% | The variety of credit types you have |
| New credit inquiries | ~10% | Recent applications for new credit |
Those weights are approximate. Equifax and TransUnion don’t publish the exact algorithm, and FICO scoring varies slightly. But this is the framework that matters.
1. Payment History (~35%)
This is the single biggest driver. Lenders want to know one thing above all else: when you owe money, do you pay it on time?
What’s tracked:
- On-time payments on credit cards, loans, lines of credit, mortgages
- Late payments, flagged at 30, 60, 90, and 120+ days late
- Accounts in collections
- Bankruptcies, consumer proposals, or court judgments
- Charge-offs and write-offs
The damage from a single late payment is real. A single 30-day late payment can drop a healthy score by 60 to 110 points, and the mark stays on your credit report for up to 6 years in Canada.
What helps:
- Set up autopay for at least the minimum payment on every account. Autopay-minimum protects against late marks even when life gets busy.
- If you miss a payment, pay it as soon as you realize, then call the lender. Lenders can sometimes choose not to report a 30-day late if you catch it within a few days, you just have to ask.
- Don’t ignore old debts in collections. Settling or paying them won’t erase the history, but it does add a “paid” status that scoring models look at favourably.
2. Credit Utilization (~30%)
Credit utilization is the percentage of your available revolving credit you’re using at any given moment. If you have a credit card with a $5,000 limit and a $1,500 balance, your utilization on that card is 30%.
The scoring models care about both:
- Per-card utilization (each card individually)
- Total utilization (all your revolving credit added together)
What helps:
- Keep utilization under 30%. Below 10% is even better. This is the single fastest way to lift your score short of fixing late payments.
- Pay before the statement closes, not just before the due date. Paying early lowers the balance your issuer reports, and the timing is walked through in building credit with a credit card.
- Ask for a credit limit increase. If your habits don’t change but your limit goes up, your utilization ratio drops automatically. Most banks will consider an increase after 6 to 12 months of clean account history.
- Don’t close old cards with available limits. Closing reduces your total available credit and can spike your utilization ratio overnight.
Utilization is also unique in that it has no memory. Pay your balance down today and your score will reflect it on the next reporting cycle. That makes utilization the single fastest score-improvement lever.
3. Length of Credit History (~15%)
Lenders trust borrowers who’ve shown patterns over time. The bureaus look at:
- Age of your oldest account (the longer, the better)
- Age of your newest account
- Average age across all accounts
This is one of the harder factors to manipulate. Time is the only real input. But two habits matter:
What helps:
- Keep old accounts open, even if you don’t use them. The old card you forgot about in your drawer is silently boosting your score.
- Use old cards at least once a year so the issuer doesn’t close them for inactivity. A small recurring charge (like a $9.99 subscription) followed by autopay-in-full keeps the account active without adding any cost.
What hurts:
- Closing your oldest credit card can take years off your average and visibly drop your score even if you owe nothing
- Opening many new accounts in a short window pulls your average age down
4. Credit Mix (~10%)
Lenders prefer borrowers who can manage different types of credit responsibly. Two main categories:
- Revolving credit: credit cards, lines of credit, home equity lines (HELOCs)
- Installment credit: personal loans, car loans, mortgages, student loans
A score built only on credit cards is “thinner” than a score built on a credit card plus an installment loan paid on time over a few years. That’s why a bad credit installment loan can be a useful credit-rebuilding tool, it adds the installment side of the mix.
What helps:
- Hold at least one revolving account (a credit card) and one installment account (a loan) over time
- Don’t open accounts you don’t actually need just to “improve mix”, the new-credit penalty cancels the mix benefit
5. New Credit Inquiries (~10%)
Every time a lender pulls your credit file to evaluate an application, that’s recorded as a hard inquiry. Hard inquiries stay on your credit report for up to 36 months, and Equifax Canada says one usually will affect your scores. Neither Canadian bureau publishes a fixed points figure per inquiry, so treat any specific number you see quoted elsewhere with caution.
The real damage comes from clusters: multiple hard inquiries in a short window signal that you’re shopping aggressively or in financial distress.
What helps:
- Use a soft-pull pre-qualification before you apply. Most credit cards and loan platforms offer “see what you may qualify for” tools that don’t ding your score.
- Use a lender-matching platform like Lend For All so a single application generates one inquiry, not five.
- Cluster rate-shopping. Mortgage and auto-loan inquiries within a 14-to-45-day window are typically grouped and counted as one inquiry, designed so rate shopping doesn’t punish you.
- Check your own credit as often as you want. When you pull your own report through Equifax, TransUnion, or a free service, it’s a soft inquiry, invisible to lenders, no score impact.
What Doesn’t Affect Your Credit Score
A few common myths worth clearing up. None of these affect your Canadian credit score:
- Your income or employment status
- Your bank account balance or savings
- Your age, marital status, or education
- Your address (other than identity verification)
- Insurance shopping, utility shopping, or apartment-rental inquiries (these are usually soft pulls)
- Checking your own score
A Realistic Order of Operations
If your score is below where you want it and you’re trying to rebuild, work the factors in this order, biggest impact first:
- Get all accounts current and stay current going forward (payment history)
- Drive utilization below 30% (and ideally below 10%) on every revolving account
- Stop opening new credit unless absolutely necessary; let inquiries age off
- Keep old accounts open to protect your length of history
- Add a missing credit type (usually an installment loan if you only have cards) once the first three are stable
Most Canadians who follow that order see meaningful score improvement within 3 to 6 months, even starting from the bad-credit range. For a deeper playbook, see our guide on smart ways to repair your bad credit.
How to Check Your Credit Score in Canada
You can check your credit score for free, as often as you like, through:
- Equifax Canada, free monthly reports through their consumer portal
- TransUnion Canada, free reports and score monitoring
- Borrowell (free service powered by Equifax data)
- Credit Karma Canada (free service powered by TransUnion data)
- Your bank’s mobile app, most major banks now show a credit score for free
These are all soft pulls. They have zero impact on your score.
Building Credit From Where You Are
Your credit score is a snapshot, not a verdict. Every month, you have new chances to add positive history. The Canadians who improve their scores fastest are usually the ones who stop trying to game the system and start treating credit like what it is, a long-term track record.
If you’re looking for a way to add an installment loan to a thin credit file, get matched with a Canadian lender today →. A small, on-time installment loan over 6 to 12 months is one of the cleanest ways to broaden your credit mix while building payment history.
