Mortgage Pre-Approval Canada

What pre-approval means, how to get one, and why it matters before you start house hunting.

What Is Mortgage Pre-Approval?

A mortgage pre-approval is a conditional commitment from a lender stating how much they are willing to lend you, at what rate, for a specified period — typically 90 to 120 days. It is based on a review of your income, credit, assets, and debts. Pre-approval gives you a firm budget to shop within and locks in an interest rate against potential increases during the rate hold period.

Pre-approval is different from pre-qualification. Pre-qualification is a quick estimate based on self-reported information — no credit check, no document verification. Pre-approval involves a full credit pull and document submission, making it a much stronger signal to sellers and agents.

Documents Required for Pre-Approval

Being prepared with the right documents speeds up the process significantly. Gather these before applying:

• Government-issued ID (passport or driver's licence)
• Social Insurance Number (SIN)
• Last 2 years' T4 slips and Notices of Assessment (NOA) from CRA
• Most recent 2–3 pay stubs
• Employment letter confirming salary, position, and start date
• 3–6 months of bank statements showing your down payment savings
• Statements for any RRSPs, TFSAs, FHSAs, or investment accounts being used for the down payment
• Details of any existing debts (car loans, student loans, credit cards)
• If self-employed: 2 years of T1 Generals and financial statements

The Pre-Approval Process Step by Step

Step	Action	Typical Timeline
1	Submit application and documents to lender or broker	1 hour
2	Lender pulls your credit report (hard inquiry)	Immediate
3	Underwriter reviews income, debts, and assets	1–3 business days
4	Pre-approval letter issued with maximum amount and rate	24–72 hours
5	Rate hold activated for 90–120 days	At issuance

What the Pre-Approval Rate Hold Means

One of the most valuable aspects of pre-approval is the rate hold. If you receive a 5-year fixed rate of 4.74% today and rates rise to 5.24% over the next 60 days while you're house hunting, your pre-approved rate is guaranteed — as long as you close within the hold period. If rates drop, most lenders will allow you to take the lower rate at closing. This asymmetry — rate hold protects you if rates rise, but you benefit if they fall — makes pre-approval an excellent hedge in volatile rate environments.

Pre-Approval vs. Full Mortgage Approval

Pre-approval is subject to conditions that must be satisfied before a lender commits fully. When you find a home and make an offer, the lender reviews the specific property to confirm it meets their requirements. Common final approval conditions include:

• Satisfactory property appraisal
• Clean title search
• No material change in your employment or income since pre-approval
• Proof of property insurance
• Final confirmation of down payment source (gift letters if applicable)

Do not make any major financial changes between pre-approval and closing. Changing jobs, buying a car, or taking on new debt can jeopardize your final approval even if your pre-approval is in hand.

Does Pre-Approval Hurt Your Credit Score?

A mortgage pre-approval triggers a hard credit inquiry, which typically reduces your credit score by a few points temporarily. However, credit bureaus treat multiple mortgage inquiries within a 14–45 day window as a single inquiry for scoring purposes — so shopping multiple lenders during this window has minimal impact. Do not apply for new credit cards, car loans, or other financing in the months leading up to your mortgage application.

Getting Multiple Pre-Approvals

It is entirely reasonable to get pre-approvals from two or three lenders simultaneously to compare rates and terms. A mortgage broker can often do this on your behalf with a single application submitted to multiple lenders, minimizing credit inquiries. Compare not just the rate, but also the prepayment privileges, penalty calculation method, and portability features of each pre-approval.
