How credit cards affect your credit score in Canada: Equifax, TransUnion, utilization and closing cards

Credit cards affect your credit score in Canada through five things the bureaus see: whether you pay on time, how much of your limits you use (utilization), how long your accounts have been open, how many new applications you make, and the mix of credit you hold. Paying on time and keeping balances low relative to your limits help most; late payments, maxed-out cards and several applications in a short period hurt. Canada has two national credit bureaus, Equifax Canada and TransUnion Canada, and scores generally range from 300 to 900. You can get your credit reports free from both, and checking your own report does not affect your score.

This guide belongs to credit card mistakes and official sources. Score models are proprietary, so the effects described here are general patterns, not exact rules.

What the bureaus record about your cards

Item	What it shows	How it tends to affect your score
Payment history	On-time, late (often by 30, 60, 90 days), in collections	The single most important factor; late payments are a strong negative
Balance and limit	Balance reported, often around the statement date, and credit limit	High utilization tends to lower scores
Account age	When each card was opened	Longer average history usually helps
Inquiries	Hard inquiries when you apply for credit	A few have a modest effect; many in a short period more
Account status	Open, closed by you, closed by the issuer, written off	Write-offs and collections are serious negatives

Lenders see the report and may also use their own scoring. The score you see on a free app may not be the exact score a lender uses.

Utilization: the factor you control monthly

Utilization = balance reported ÷ credit limit

Illustrative example. Two cards: Card 1 with a $3,000 limit and a $2,400 balance; Card 2 with a $5,000 limit and a $600 balance.

Card 1: $2,400 ÷ $3,000 = 80%
Card 2: $600 ÷ $5,000 = 12%
Overall: $3,000 ÷ $8,000 = 37.5%

Both the overall ratio and high ratios on individual cards can matter. Consumer education sources commonly advise keeping utilization well below your limits; the FCAC's guidance suggests using only a portion of your available credit. Two practical points:

Even if you pay in full, the balance reported is often the statement balance. Paying part of it before the statement date lowers the reported balance.
Lowering a limit or closing a card raises utilization on the same spending. Closing Card 2 above would push overall utilization to 100%.

Applications and hard inquiries

When you apply, the issuer usually makes a hard inquiry. A soft inquiry, such as checking your own report or a pre-qualification, does not affect your score. Several hard inquiries in a short time can suggest you are seeking a lot of credit. If you plan a mortgage application, avoid new card applications for several months beforehand. See the application checklist.

Closing a card

Closing a card can affect your score in two ways: it removes the card's limit from your available credit (raising utilization) and, over time, the closed account's history stops contributing as an open account. Closed accounts in good standing generally stay on your report for a period before being removed. Before closing:

Redeem or transfer points.
Pay the balance in full.
Consider a product change to a no-fee card at the same issuer to keep the account history.
If you close the card, confirm in writing and check your report later to see it shown as closed at your request.

Late payments and how long they last

A payment that is 30 days or more late may be reported to the bureaus. Negative information such as late payments, collections and write-offs stays on Canadian credit reports for several years: according to the FCAC, the general rule is six years, although TransUnion keeps some items longer in some provinces (seven years in Newfoundland and Labrador, Ontario and Quebec, ten in Prince Edward Island). A consumer proposal is removed 3 years after you pay it off or 6 years after you sign it, whichever is sooner; a first bankruptcy generally 6 years after discharge (7 years with TransUnion in some provinces). Check the FCAC page and the bureaus' websites for the current periods in your province.

Prevent it: set up an automatic payment of at least the minimum, even if you plan to pay more manually.

Checking your report and fixing errors

Request your free report from Equifax Canada and TransUnion Canada online, by mail or by phone.
Check personal details, every account listed, balances, late payments and inquiries.
If something is wrong, file a dispute with the bureau and, ideally, ask the card issuer to correct what it reported.
If an account you don't recognize appears, treat it as possible identity theft; see fraud.
Provincial credit reporting laws give you rights to access and correct your file; the provincial consumer protection office can help if a bureau does not respond.

Building credit with cards

New to Canada or no history: a secured card or a newcomer program; use it for small regular purchases and pay in full.
Rebuilding after problems: on-time payments over time do more than any single action. Paying for a "credit repair" service that promises to remove accurate negative information is a waste of money.
Authorized user: being an additional cardholder may or may not build your own history, depending on how the issuer reports; ask.

Frequently asked questions

Does paying in full every month build credit?

Yes. Paying in full shows on-time payment history and avoids interest. You do not need to carry a balance to build credit.

Does a balance transfer hurt my score?

Opening a new card for the transfer adds an inquiry and a new account. Moving the balance can change per-card utilization. Paying the debt down helps.

Will asking for a credit limit increase lower my score?

Some issuers make a hard inquiry for a limit increase; ask first. A higher limit can lower utilization if your spending stays the same. The bank needs your express consent for any increase.

Is my score the same at both bureaus?

Not necessarily. Lenders report to one or both, and the bureaus' models differ.
