A mortgage pre-approval is a lender’s opinion of how much you can likely borrow, based on the documents you have given them so far, plus a rate hold that usually runs 90 to 120 days. It is not a promise to fund your purchase. The lender still has to review the property you actually buy, confirm your income and credit have not changed, and be satisfied with the appraisal. That gap between “pre-approved” and “approved” is where most GTA buyers get caught.
THE QUICK VERSION
A pre-approval holds a rate and gives you a working budget. It does not commit the lender to fund the purchase.
Final approval depends on the property. The appraisal, the condo status certificate, the property type and the location all get reviewed after you have an accepted offer.
Keep a financing condition in your offer unless there is a clear reason not to, and talk to your broker before you waive it.
What does a pre-approval actually give you?
Three things, and they are worth having. First, a rate hold, so if rates move up while you are shopping, you keep the rate you were quoted. If rates move down, most lenders will give you the lower one, but confirm that with your broker rather than assuming it. Second, a realistic budget built from your actual income, credit and debts instead of a guess. Third, credibility with a listing agent, which matters in a competitive GTA offer.
What it does not give you is certainty. A pre-approval is issued before anyone has looked at a property. The lender has assessed you. It has not assessed the house.
Why is the pre-approval number lower than the online calculator said?
Usually the stress test, and sometimes debts you forgot to count. With a federally regulated lender you have to qualify at the higher of your contract rate plus two percent, or 5.25 percent. You make payments at your real rate, but you qualify at the higher one. In practice that trims borrowing power by roughly 15 to 20 percent compared with qualifying at the contract rate, though the exact effect depends on your income, debts and down payment.
The second reason is monthly obligations. A car payment, a student line of credit, a card you carry a balance on, support payments — each one reduces the mortgage you qualify for, sometimes by more than people expect. A car loan in particular can move the number meaningfully. Online calculators rarely ask about any of this, which is why the calculator figure and the pre-approval figure often disagree.
A rough example, to show the shape of it.
Two buyers in Mississauga, same household income, same 20 percent down payment. One has no monthly debts. The other carries a $650 car payment and a $200 minimum on a line of credit.
That $850 a month does not just reduce the budget by $850. It comes off the income the lender can apply to housing costs, and the mortgage is then sized at the stress-test rate. The second buyer can often qualify for well over $100,000 less. Figures are illustrative only — your own numbers depend on your income type, credit, property and lender.
Can you be declined after you have been pre-approved?
Yes, and it happens more often than people realise. The common reasons are straightforward once you know to watch for them.
- The property. A low appraisal, an unusual condo, a rural or mixed-use property, or a building the lender will not take.
- A change in income. Switching jobs, moving from salary to contract, or starting a probation period between the pre-approval and closing.
- New debt. Financing furniture, a car, or a renovation before closing.
- Down payment source. Funds that cannot be traced, or a gift that arrives without a proper gift letter.
- Credit changes. A missed payment or a jump in balances between pre-approval and final approval.
The practical rule is to change nothing. Between the pre-approval and the closing date, keep your job, keep your balances where they are, and do not finance anything. If something has to change, tell your broker before it happens rather than after.
Should you make an offer without one?
You can, but you are carrying the risk yourself. If you buy firm with no financing condition and the mortgage does not come together, the deposit and potentially more is on the line. This is a real risk in the GTA, where firm offers are common in competitive listings. If you are considering it, understand what you are giving up first — we walk through that in more detail in making an offer before you are pre-approved.
Should you borrow the full pre-approved amount?
The pre-approval is a ceiling, not a target. It tells you what a lender is comfortable with. It does not tell you what fits your life. Property taxes, condo fees, home insurance, utilities, maintenance and the cost of getting to work all sit outside the mortgage payment, and none of them appear on the pre-approval letter.
It is also worth setting aside for the one-time costs. Ontario land transfer tax, the additional Toronto municipal land transfer tax if you are buying in the city, legal fees, title insurance, the appraisal and moving costs all land in the same few weeks. First-time buyers may qualify for land transfer tax rebates, which helps, but the closing costs beyond the down payment still need to be planned for.
What if your income is not straightforward?
Then the pre-approval is worth even more, and it needs more care. If you are self-employed, on commission, on contract, or new to Canada with limited Canadian credit history, the standard pre-approval process often understates what you can actually do. The income is real. It just does not present the way a bank’s template expects.
In those cases the useful work happens before the application: choosing the right lender for your income type, deciding which documents tell the clearest story, and knowing in advance which questions an underwriter will ask. A pre-approval issued without that groundwork can give you a number you cannot rely on.
What should you do before you start looking?
- Pull your own credit report from Equifax or TransUnion and check it for errors before a lender does.
- Confirm your down payment is traceable — 90 days of history for the funds, and a gift letter if any of it is gifted.
- Gather your income documents — recent pay stubs and a job letter, or your last two Notices of Assessment and T1 Generals if you are self-employed.
- List every monthly obligation, including the ones you would rather not count.
- Ask what the pre-approval assumed — the rate, the amortization, the property taxes and the heating cost used in the calculation.
If you want to see the mechanics for yourself first, the calculators in our resource centre are a reasonable starting point, and the glossary covers the terms that come up. Our mortgage pre-approval page explains how we handle the review, and the first-time home buyer page covers the wider picture.
Here is the main point. A pre-approval is a checkpoint, not a finish line. It is most useful when the numbers behind it have been reviewed properly and you understand what could still change. Before you start writing offers, it is worth an hour to look at the full picture.
Common questions about mortgage pre-approval
How long does a mortgage pre-approval last in Ontario?
Most pre-approvals hold for 90 to 120 days, though some lenders run shorter or longer. The rate hold expires with it. If you are still looking when it runs out, it can usually be renewed, but the lender will re-check your credit and income at that point, and the rate available then may be different.
Is a pre-approval a guarantee that I will get the mortgage?
No. It is a lender’s assessment of you based on what you have provided so far, subject to conditions. Final approval also depends on the property you buy, the appraisal, and confirmation that your income, credit and debts have not changed.
Does getting pre-approved hurt my credit score?
A pre-approval involves a hard credit check, which typically costs a few points and recovers within a few months. Multiple mortgage inquiries made within a short window are generally treated as one, so comparing lenders around the same time is far better than spreading applications across several months.
Can I get pre-approved with more than one lender?
You can, and it is reasonable to compare. Keep the applications close together so the credit inquiries are grouped. A broker can compare several lenders from one application rather than having you apply separately to each.
Can I still be declined after I have been pre-approved?
Yes. The usual causes are a low appraisal or a property the lender will not accept, a change in employment, new debt taken on before closing, a down payment that cannot be traced, or a drop in credit. Keeping your file unchanged between pre-approval and closing is the single most useful thing you can do.
What is the difference between a pre-qualification and a pre-approval?
A pre-qualification is an estimate based on numbers you state, with nothing verified. A pre-approval involves a credit check and a review of your actual documents, and normally comes with a rate hold. The two can produce very different figures, and only the pre-approval carries weight with a listing agent.
