Mortgage Pre-Approval in Ottawa: How It Works and What You Need

By the Ottawa Mortgages editorial team · Last reviewed: September 2026 · How we write our guides

What is a mortgage pre-approval? A pre-approval is a lender’s estimate of how much you may be able to borrow, based on your income, debts, credit and down payment. It usually includes a rate hold of up to 120 days, but it is not a final approval. The property and your documents are still reviewed before the mortgage is confirmed.

In Ottawa’s competitive market, buyers often get pre-approved before they start viewing homes. A pre-approval helps you set a realistic budget, shows sellers you are serious, and locks in a rate while you shop.

Pre-qualification vs pre-approval vs final approval

StageWhat it involvesHow reliable is it?
Pre-qualificationA quick estimate from the details you provide. Often no credit check.A rough guide only
Pre-approvalLender reviews your documents and credit and issues a maximum amount and rate hold.Strong, but conditional on the property and unchanged finances
Final approvalLender approves the property and your complete file, often after an appraisal.Confirmed, subject to closing conditions

Documents lenders usually ask for

  • Government photo ID
  • Recent pay stubs and a letter of employment
  • Last two years of T4s and Notices of Assessment (self-employed borrowers may need more)
  • 90 days of bank statements showing your down payment
  • Details of debts such as loans, credit cards and child support
  • A gift letter if a family member is helping with the down payment

What can affect your pre-approval

  • New debt, such as a car loan or new credit card, before closing.
  • A job change or reduced income.
  • A drop in your credit score.
  • Rate holds expiring before you find a home.
  • The appraisal coming in below the purchase price.

How to use your pre-approval wisely

  1. Treat the maximum amount as a ceiling, not a target. Budget for property tax, insurance and maintenance.
  2. Ask whether the rate hold gives you the lower rate if rates fall.
  3. Keep your finances steady until you close. Avoid new credit.
  4. Talk to your broker before you increase your offer.

Frequently asked questions

Does a pre-approval affect my credit score?

Lenders usually run a credit check, which can cause a small, temporary dip. Multiple mortgage inquiries in a short time are typically treated as one for scoring, but confirm with your broker.

Is a mortgage pre-approval guaranteed?

No. It depends on the property, your unchanged finances, and the lender’s final review.

How long does a pre-approval last?

Many lenders hold the rate for 90 to 120 days. You can often extend it by updating your documents.

How much can I borrow in Ottawa?

It depends on your income, debts, credit and down payment. Lenders use debt service ratios and the mortgage stress test to set your maximum. A broker can calculate this for you.

Should I get pre-approved by more than one lender?

A broker can compare lenders through a single application. Applying directly with several lenders can result in multiple credit checks.
