Touring homes before you know what you can actually borrow is a good way to fall for something outside your range. A mortgage pre-approval fixes that. It gives you a real number to shop with, and it tells sellers and listing agents you're a serious buyer the moment you write an offer. Here's what the process actually involves.

A quick note before we get into it: this is general information, not financial or lending advice. Mortgage rules, rates, and program details change and vary by lender. Confirm current numbers with a licensed mortgage professional before making any decisions.

Pre-Qualification vs. Pre-Approval

These two terms get used interchangeably, but they're not the same thing. Pre-qualification is a quick, informal estimate based on numbers you self-report. No documents, usually no credit check, and it gives you a rough ballpark. Pre-approval is the formal version: a lender actually verifies your income, credit, and debts, then issues a specific approved amount, often with a rate hold attached. If you're serious about touring homes, pre-approval is the one that matters.

The Mortgage Stress Test

Every mortgage applicant in Canada, regardless of down payment size, has to qualify at a rate higher than what they'll actually pay. The qualifying rate is whichever is higher: your contract rate plus 2 percent, or a floor of 5.25 percent. With 5-year fixed rates recently sitting in the 4.0 to 4.3 percent range, that puts the effective qualifying rate around 6.0 to 6.3 percent for most borrowers. OSFI confirmed in January 2026 that these rules remain unchanged. What that means practically: the amount you're pre-approved for will be lower than what your monthly payment would suggest you can afford at today's actual rate. That gap is intentional. It's a buffer built in case rates rise before your renewal.

Down Payment Basics

On an insured mortgage, the minimum down payment is 5 percent on the first $500,000 of the purchase price, plus 10 percent on the portion between $500,000 and $1.5 million. The insured price cap sits at $1.5 million, raised from $1 million in December 2024. Homes priced at or above $1.5 million require at least 20 percent down and can't be insured at all. Anything under 20 percent down requires mortgage default insurance through CMHC, Sagen, or Canada Guaranty, which adds a premium to your mortgage. Worth flagging for Oakville specifically: with many neighbourhoods averaging well above the $1.5 million insured cap, plenty of local buyers end up in conventional, 20-percent-plus financing rather than insured territory, which changes both the down payment math and the products available. Acceptable sources for your down payment include personal savings, an RRSP withdrawal through the Home Buyers' Plan, an FHSA withdrawal, or a non-repayable gift from an immediate family member (with a signed gift letter confirming it isn't a loan).

Documents to Gather Before You Apply

☐ Government-issued photo ID

☐ Two recent pay stubs

☐ Your most recent T4

☐ Your latest Notice of Assessment (NOA)

☐ A letter of employment

☐ 90 days of bank statements showing your down payment funds

☐ A signed gift letter, if part of your down payment is a gift from an immediate family member

How Long Does a Pre-Approval Last?

Rate holds typically run 60 to 130 days, depending on the lender and whether you're buying a new build or an existing home. If your house search runs longer than your hold, you'll likely need to renew or re-verify, and the rate you're offered could move in either direction by then. Worth keeping in mind if you're touring during a slower season and taking your time.

Two Programs Worth Knowing About

The First Home Savings Account (FHSA) lets you contribute up to $8,000 per year, up to $40,000 over your lifetime, with tax-deductible contributions like an RRSP and tax-free withdrawals for a first home like a TFSA. Unlike the Home Buyers' Plan, you never have to pay it back.Ontario also offers a land transfer tax rebate for first-time buyers of up to $4,000, which fully covers the provincial land transfer tax on lower-priced homes and reduces it on higher-priced ones. One note for Oakville buyers specifically: this is the provincial rebate only. Toronto has an additional municipal land transfer tax and matching municipal rebate that Oakville, as part of Halton Region, does not charge, so there's no separate municipal rebate to claim here.

Why This Matters Before You Start Touring

Knowing your real, lender-verified number keeps you from falling for a home outside your range, and it makes your offer more credible the moment you're competing against other buyers. In a market where the right home in the right neighbourhood can move quickly, having your pre-approval already in hand means we can move on it the same day it's listed instead of losing time to paperwork.We work with a network of local mortgage brokers who can walk you through numbers specific to your situation.
