What is a mortgage pre-approval in Canada?
Updated: February 28, 2026CanadaFAQPrivate lending
Quick Summary
A pre-approval estimates how much you can borrow and may hold a rate for a limited time, but it is not a final guarantee of funding.
A pre-approval is a useful planning tool, but it’s easy to misunderstand what it does.
What a pre-approval usually gives you
- An estimate of your maximum mortgage amount (based on income, debts, and credit).
- A rate hold for a set period (the exact length varies by lender).
- A checklist of conditions the lender will require to fully approve the mortgage.
What can still change before final approval
- Your credit or debts (new credit cards, car loans, missed payments).
- Your income documentation (self-employed and variable income are common friction points).
- The property (Appraisal value, condo status, condition, location, and lender guidelines).
How to use a pre-approval properly
- Treat the number as a ceiling, not a budget.
- Avoid taking on new debt before closing.
- Ask your broker what documents will be re-checked at firm approval.
If you’re buying with a tight closing timeline, ask early whether the lender can meet the deadline and what could delay Underwriting.
