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 after about 12 months. Understanding when a hard pull is triggered — and when it isn’t — helps you apply for credit strategically without unnecessary score damage.
Hard inquiry vs. soft inquiry: comparison
| Inquiry Type | Who Initiates It | Affects Score? | Visible to Other Lenders? | Examples |
|---|---|---|---|---|
| Hard inquiry | Lender (with your permission) | ✅ Yes (temporarily) | ✅ Yes | Mortgage, credit card, car loan, HELOC, personal loan, cell phone contract |
| Soft inquiry | You or third party | ❌ No | ❌ No | Own credit check, employer background check, insurer check, pre-approved offer, existing lender review |
How long does a hard inquiry 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 even if the application was denied or you never used the credit. Only fraudulent or unauthorized inquiries can be disputed and removed early.
Score impact timeline
| Time After Hard Inquiry | Score Impact |
|---|---|
| Month 1 | −5 to −10 points (most of the impact occurs immediately) |
| Month 3 | Slight additional recovery as score adjusts |
| Month 6 | Score largely restored for a single inquiry |
| Month 12 | Inquiry has minimal scoring weight; essentially negligible |
| Year 2–3 (Equifax) | Inquiry still visible on report but near-zero effect |
| Year 2–6 (TransUnion) | Same — visible but insignificant |
Cumulative impact: Multiple hard inquiries compound. Three hard inquiries in 3 months is not three separate −5 point hits — the total impact can be −20 to −40 points because models weigh inquiry clusters as a risk signal.
Activities that trigger a hard inquiry in Canada
| Activity | Hard Inquiry? | Notes |
|---|---|---|
| Applying for a credit card | ✅ Yes | Every application, even if denied |
| Mortgage application | ✅ Yes | Most lenders pull both Equifax and TransUnion |
| Car loan or lease | ✅ 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 financing) | ✅ Yes | Carriers often pull credit |
| Rental application | Sometimes | Some landlords use hard pulls; ask in advance |
| Pre-approval (mortgage) | ✅ Yes | Counts as a hard inquiry |
| Pre-qualified offer in the mail | ❌ No | This is a soft pull by the lender |
| Checking your own credit | ❌ Never | Always a soft inquiry |
| Employer background check | ❌ No | Soft pull; requires your consent |
| Insurance quote | ❌ No | Soft pull |
Rate shopping: how to limit inquiry impact
For mortgages and auto loans, Canadian bureaus apply a rate-shopping window:
| Loan Type | Rate Shopping Window |
|---|---|
| Mortgage | 14–45 days (multiple inquiries treated as one) |
| Auto loan | 14–45 days |
| Personal loan / credit card | No window — each counts independently |
Strategy: When comparing mortgage or auto loan rates, submit all applications within a 14-day window. The bureaus recognize this as rate shopping and count the cluster as a single inquiry.
What happens to an unauthorized hard inquiry
If you find a hard inquiry on your report that you did not authorize:
- Pull your full report from Equifax and TransUnion
- Identify the lender that made the pull
- Contact the lender — they must have written authorization on file; request a copy
- If no authorization exists, file a dispute with the bureau:
- Equifax Canada: equifax.ca → consumer dispute
- TransUnion Canada: transunion.ca → consumer dispute
- The bureau investigates and must remove unauthorized inquiries
An unauthorized inquiry can also be a sign of identity theft — check all accounts on your report for unauthorized accounts as well.
How many hard inquiries does a typical Canadian have?
| Inquiry Count (12 months) | Category | Lender View |
|---|---|---|
| 0 | Inactive credit seeker | Neutral — may indicate no credit need |
| 1–2 | Normal | Expected; no concern |
| 3–4 | Moderate | May trigger questions at some lenders |
| 5–6 | High | Could raise flags; some automatic denials at conservative lenders |
| 7+ | Very high | Material risk signal; score meaningfully reduced |
