Whether you're applying for your first credit card, your fifth, or your first in a while, it's natural to worry that simply asking might set you back. The good news: the effect is usually small, and it doesn't last. Here's what actually happens, in plain language.
Does applying for a credit card affect your credit score?
Yes, usually. When you apply, the lender checks your credit, which creates a "hard inquiry," a formal review that may temporarily lower your score by a modest amount. For most people, any dip is minor and short-lived. The effect isn't guaranteed, and it varies from person to person.
So a single application is rarely something to fear. What matters far more is how you manage credit over time.
This article covers the difference between hard and soft inquiries, why the impact varies, how long an inquiry stays on your report in Canada, when applying can hurt more, how it can help over time, and how to check your own score safely.
Hard vs. soft inquiries: what's the difference?
A hard inquiry happens when a lender checks your credit because you applied for something, such as a credit card, a vehicle loan, or a mortgage. It appears on your credit report and may affect your score.
A soft inquiry happens when your credit is checked for reasons that aren't a formal application, such as checking your own score or receiving a pre-approved promotional offer. Soft inquiries only appear on the version of the report you see, and they have no impact on your score.
Here's a quick reference for common actions:
Action | Inquiry type | Why |
|---|---|---|
| Applying for a credit card | Hard | Lender pulls your full report to decide |
| Applying for a car loan or lease | Hard | Full creditworthiness check |
| Applying for a mortgage | Hard | Full creditworthiness check |
| Applying for a personal or student loan | Hard | Full creditworthiness check |
| Checking your own credit score | Soft | Reviewing your own file never counts against you |
| Receiving a pre-approved or promotional offer | Soft | Lender pre-screens without pulling your full report |
| Getting pre-qualified through a soft check | Soft | Preliminary look before any real application |
| Employer background check | Soft | Not a lending decision |
| Getting an insurance quote | Soft | Underwriting review, not a credit application |
| Apartment / tenant screening | Soft | Landlords typically run a soft check in Canada |
| Setting up utilities (electricity, gas, internet) | Soft | Usually a soft check to decide whether a deposit is needed |
| Requesting a credit limit increase | Usually soft | Often soft in Canada, though it varies by issuer |
| Signing up for a phone / cell plan | Depends | A postpaid contract—especially with a financed phone—may trigger a hard check; prepaid generally won't. Ask the carrier which they run |
How much does one application lower your score?
There's no fixed number. Equifax notes there is no set rule for how many points an inquiry may cost, because scores are calculated differently across bureaus and scoring models. TransUnion Canada similarly describes inquiries as having only a small impact on your score, with some checks, such as viewing your own file, having no impact at all.
The impact depends a lot on your overall credit profile. People with shorter or thinner credit histories are more likely to see a drop from a new inquiry. Those with a long, solid history may see little or no change at all.
In other words, one inquiry is a single data point among many. It's weighed alongside your payment history, balances, and the age of your accounts.
How long does a hard inquiry stay on your credit report in Canada?
According to the Financial Consumer Agency of Canada (FCAC), inquiries stay on your credit report for 3 years with Equifax and 6 years with TransUnion. That works out to about 36 months for Equifax and twice as long for TransUnion.
Staying on your report and actively affecting your score aren't the same thing. An inquiry can remain visible for years while its influence on your score fades. The retention period is simply how long the record is kept.
When applying can hurt your score more
A single application is usually minor. Several applications in a short window can matter more, because multiple new accounts can signal higher risk to lenders.
New accounts also lower the average age of your credit, which can weigh on your score. That effect tends to be larger if your file is thin or your accounts are relatively young.
There's an important nuance around rate shopping. For some loans, multiple inquiries for the same purpose within a window of 14 to 45 days, depending on the scoring model, may be counted as a single inquiry. This deduplication generally applies to shopping for mortgages or vehicle loans, not credit cards. Each credit card application is typically treated as its own separate hard inquiry.
How applying can help your credit score over time
A new card can support your credit over the long run, well after any short-term dip fades. Payment history is typically the most heavily weighted factor in your score, so a record of on-time payments works in your favour.
Keeping balances low also helps. A common guideline is to keep your credit utilization, the share of your available credit you're using, at or below 30%.
So it can be useful to think in two timeframes. The inquiry is a small, short-term event. Consistent, responsible use is the longer story that tends to carry more weight.
How to minimize the impact when you apply
A few habits can help keep any effect small:
Look for pre-approval or pre-qualification that uses a soft check first, since soft inquiries don't affect your score.
Space out applications rather than applying for several cards in a short period.
Apply for cards you're realistically likely to qualify for, based on the eligibility details lenders publish.
Check your own credit score beforehand, which is a soft inquiry and won't hurt your score.
None of this guarantees approval or a specific outcome. It simply reduces the number of hard inquiries and helps you apply with a clearer picture.
How to check your credit score without hurting it
Checking your own credit report or score won't affect your credit rating, because a self-check is a soft inquiry. You can check as often as you like.
In Canada, the two national credit bureaus are Equifax and TransUnion. You can request your own credit report and score directly from them, and many Canadian banking and personal finance services also offer free access using a soft pull.
Since your score can differ between bureaus and scoring models, it's normal to see slightly different numbers depending on where you look.
The bottom line
Applying for a credit card usually creates a hard inquiry that may lower your score by a small amount for a short time. The effect isn't guaranteed, and it's often minor, especially if you already have a solid credit history.
The bigger picture matters more than any single inquiry. On-time payments, low balances, and a longer history of responsible use carry more weight over time.
So if you need a card and are likely to qualify, one thoughtful application is rarely worth losing sleep over. Space out your applications, keep balances manageable, and check your own score whenever you like.
