A hard inquiry in Canada leaves a record on your credit report for 3 years (Equifax) or 6 years (TransUnion), but its practical effect on your score fades significantly after 12 months. The distinction between those two timelines matters: the report record is visible to lenders for years, but the scoring penalty diminishes to near zero well before the record disappears. Understanding when a hard pull is triggered — and when it is not — lets you apply for credit strategically without unnecessary score damage. This article is part of the Canadian credit scores hub.
The most costly mistake is applying for multiple credit products in a short window. A single hard inquiry costs 5–10 points and recovers in 12 months. Three credit card applications in three months can cost 20–40 points and signals credit-seeking behaviour to every lender who pulls your file in the following year. The inquiry cluster itself is as damaging as the individual inquiries — scoring models treat bunched applications as a risk signal independent of the score drop.
The flip side is equally important: rate shopping for a mortgage or car loan across multiple lenders carries essentially no penalty if done within the rate-shopping window. That window exists precisely to encourage comparison shopping for major loans.
Hard Inquiry vs. Soft Inquiry
| Inquiry Type | Who Initiates It | Affects Score | Visible to Other Lenders | Examples |
|---|---|---|---|---|
| Hard inquiry | Lender (with your consent) | Yes | Yes | Mortgage, credit card, car loan, HELOC, personal loan, cell phone financing |
| Soft inquiry | You or third party | No | No | Own credit check, employer background check, insurance quote, pre-approved offer, existing lender review |
The consent requirement for hard inquiries is legally significant. Under PIPEDA, a lender must have your authorization before pulling your full credit report. A lender who runs a hard inquiry without your knowledge or consent has violated your privacy rights — that inquiry can be disputed and removed.
How Long Hard Inquiries Stay on Your Report
| Bureau | Hard Inquiry Retention |
|---|---|
| Equifax Canada | 3 years from the date of inquiry |
| TransUnion Canada | Up to 6 years from the date of inquiry |
The inquiry stays on your report for the full period regardless of the application outcome — whether approved, denied, or withdrawn. Only fraudulent or unauthorized inquiries can be disputed and removed before the retention period ends.
Score Impact Timeline
The scoring penalty does not persist for the full retention period. The impact curve looks like this:
| Time After Hard Inquiry | Score Impact |
|---|---|
| Month 1 | −5 to −10 points (most of the impact occurs immediately) |
| Month 3 | Slight recovery as the recency of the inquiry fades |
| Month 6 | Score largely restored for a single inquiry |
| Month 12 | Inquiry has minimal scoring weight — essentially negligible |
| Year 2–3 (Equifax) | Visible on report but near-zero scoring effect |
| Year 2–6 (TransUnion) | Visible but insignificant |
The critical variable is inquiry clustering. A single hard inquiry costs 5–10 points and is largely irrelevant after six months — see what your score range means to understand how much each point matters. But three inquiries in three months do not cost 15–30 points — they can cost 20–40 points because the scoring model treats the cluster as a distinct risk signal beyond the sum of individual inquiries. Multiple applications in a short period tell the model that you are seeking credit urgently, which is associated with higher default risk. The penalty for that signal decays more slowly than the penalty for a single inquiry.
What Triggers a Hard Inquiry in Canada
| Activity | Hard Inquiry | Notes |
|---|---|---|
| Credit card application | Yes | Every application, even if denied |
| Mortgage application or pre-approval | Yes | Most lenders pull both Equifax and TransUnion |
| Car loan or lease application | Yes | Usually TransUnion; rate-shopping window applies |
| Personal loan application | Yes | |
| HELOC or home equity loan | Yes | |
| Line of credit application | Yes | |
| Cell phone contract with device financing | Yes | Carriers often pull credit |
| Rental application | Sometimes | Some landlords use hard pulls — ask before applying |
| Mortgage pre-qualification (no formal application) | Sometimes | Depends on lender; ask explicitly |
| Pre-qualified offer received in the mail | No | Soft pull by the lender |
| Checking your own credit report or score | No | Always a soft inquiry |
| Employer background check | No | Soft pull; requires your consent |
| Insurance quote | No | Soft pull |
Pre-approvals deserve special attention. For mortgages, a formal pre-approval letter — the document you present to a vendor to demonstrate you can finance the purchase — almost always involves a hard pull. Some lenders offer a preliminary “pre-qualification” assessment using a soft pull, but the formal pre-approval is hard. Confirm which you are getting before proceeding.
Rate Shopping: How to Limit Inquiry Damage
The rate-shopping deduplication window is one of the most consumer-friendly features of Canadian credit scoring. It exists specifically because comparison shopping for major loans should not be penalized.
| Loan Type | Rate-Shopping Window |
|---|---|
| Mortgage | 14–45 days (multiple inquiries treated as one) |
| Auto loan | 14–45 days |
| Personal loan | No window — each counts independently |
| Credit card | No window — each counts independently |
For mortgages and auto loans, submit all applications within a concentrated window — ideally 14 days — to ensure the bureaus group the inquiries. Spreading applications over six weeks risks losing the grouping benefit at one or both bureaus (Equifax and TransUnion use slightly different windows).
For credit cards and personal loans, there is no deduplication. Each application is its own hard inquiry. If you plan to apply for a credit card and a car loan in the same period, apply for the card first (or leave at least six months between them) to minimize the compounding inquiry effect.
What to Do If You Find an Unauthorized Hard Inquiry
An inquiry you did not authorize is a privacy violation and a potential sign of identity theft. Take these steps:
- Pull your full report from both Equifax (equifax.ca) and TransUnion (transunion.ca) — free annually under Canadian law
- Identify the lender that ran the inquiry
- Contact that lender and ask them to produce the written authorization they have on file for the pull
- If no authorization exists, file a written dispute with the bureau — Equifax Canada via equifax.ca, TransUnion Canada via transunion.ca
- While the investigation is open, review all accounts on your report for any you did not open — an unauthorized inquiry is frequently accompanied by fraudulent account opening
The bureau is legally required to investigate disputed inquiries. If the inquiry is confirmed unauthorized, it will be removed. The investigation typically completes within 30 days.
Inquiry Count: What Lenders See
| Hard Inquiries in 12 Months | Category | How Lenders Interpret It |
|---|---|---|
| 0 | Inactive | Neutral — may indicate no credit need |
| 1–2 | Normal | Expected; no concern |
| 3–4 | Moderate | May trigger questions at some lenders |
| 5–6 | High | Raises flags; some automatic additional scrutiny |
| 7+ | Very high | Material risk signal; some lenders decline automatically |
Lenders see all hard inquiries on your report, not just their own. A mortgage underwriter reviewing your application will see that you applied for three credit cards in the prior six months. This may not cause a denial, but it will generate questions and may affect the rate or terms offered.
