How Credit Scores Are Built in Canada

In Canada, your credit score is built from the contents of your credit report — a running record of how you have borrowed and repaid. There is no single number that appears out of nowhere. Lenders and other data providers send information to credit bureaus, the bureaus assemble it into a file, and a scoring model turns that file into a number. That is the whole machine. Knowing how it works changes how you approach your next loan application.

One thing to clear up first: LoanGoose is a loan matching and comparison service, not a lender. We do not set rates, make credit decisions, or see your score. The information below is general, and the right move for your situation depends on your circumstances.

What actually goes into a credit score

A credit score is a summary of risk, expressed as a number. The Financial Consumer Agency of Canada explains that scoring models look at things like whether you pay your bills on time, how much of your available credit you are using, how long your accounts have been open, the mix of credit you hold, and how often you apply for new credit (FCAC — credit reports and scores).

Notice what is not on that list: your income, your job title, your savings, and your net worth. Those matter to lenders, but they do not live in your credit file. A score is only about how you have handled credit so far.

Scoring models do not weight every ingredient equally. Payment history tends to carry the most weight; new-credit inquiries tend to carry the least. The exact recipe is proprietary and varies by bureau and model, so nobody outside the bureaus can hand you the precise math. What you can control is the raw material you feed in.

Where the raw material comes from

Canada has two national credit reporting bureaus: Equifax Canada and TransUnion Canada (FCAC — credit reports and scores). Most lenders report to one or both. That is why your two scores can differ — the underlying files are not identical.

You are entitled to a free copy of your credit report from each bureau (FCAC — credit reports and scores). The report is the file; the score is a snapshot derived from it. Reading the report is how you catch errors before a lender does.

The ingredients, in plain terms

That table is a map, not a scorecard. There is no published formula that says a missed payment costs you a set number of points, because no such public formula exists.

What moves a score up or down

• On-time payments. The most consistent signal. A history of paying as agreed is the foundation.
• Balances relative to limits. Running a card near its limit looks riskier than using a small share of it, even if you pay in full.
• Age of accounts. A long, boring history is an asset. Closing your oldest account can shorten it.
• Applications. Each hard inquiry shows that a lender checked your file. A cluster of them in a short window can signal strain.
• Errors. A mistaken late payment or a debt that is not yours drags the file down until it is corrected.

If you are rebuilding, the honest trade-off is time. There is no switch. The FCAC has plain-language material on FCAC — debt and borrowing that covers the basics of managing what you owe.

How lenders use it before you borrow

Your score is one input among several. A lender also looks at income, existing debts, and the specific product. For a mortgage from a federally regulated lender, that picture gets more formal: underwriting generally works to a total debt service ratio ceiling of about 44%, and lenders apply a qualifying stress-test rate above the contract rate (OSFI Guideline B-20). A strong score helps, but it does not override the math.

For personal loans, the FCAC notes that what you are offered depends on the lender's assessment of you and the terms you choose (FCAC — personal loans). Two people with similar scores can be quoted differently.

Also worth knowing: Canadian fixed-rate mortgages are compounded semi-annually by law. That convention affects the effective cost, not your score, but it is part of the borrowing picture.

When a file takes a hit: proposals and bankruptcies

Severe events follow their own timelines. A consumer proposal stays on a credit report for three years after completion, or six years from filing, whichever comes first. A first bankruptcy stays on a credit report for six years after discharge. Those figures come from the federal framework, and the Office of the Superintendent of Bankruptcy Canada oversees the system (Office of the Superintendent of Bankruptcy Canada). Only a licensed insolvency trustee can administer a consumer proposal or bankruptcy.

If you are weighing one of those options, that is a decision to make with a licensed insolvency trustee or a licensed credit counsellor, not from a blog post.

If something on your report is wrong

Errors happen. You can dispute them with the bureau, and if the issue is with a federally regulated financial institution, the Financial Consumer Agency of Canada handles consumer complaints (FCAC — complaints). Provinces license and supervise most other lenders, and each has a consumer protection office (FCAC — provincial and territorial regulators).

Privacy questions about your file travel a separate lane; the Office of the Privacy Commissioner of Canada deals with those (Office of the Privacy Commissioner of Canada).

A short checklist before you apply

1. Pull your free report from each bureau and read it line by line.
2. Dispute anything that is not accurate.
3. Pay every account on time, including the small ones.
4. Bring revolving balances down before applying — it is the fastest lever you control.
5. Space out applications rather than firing off several at once.
6. Compare the total cost of borrowing, not just the advertised rate.

None of this decides the outcome on its own. It simply puts you in a position where the information a lender sees matches the way you actually manage money. For a significant borrowing decision, talk to a licensed professional who can review your full situation.
