Get a pre-approval before you shop so you know your real budget and can move fast on the right home.
A pre-qualification is a quick, informal estimate of what you might be able to borrow, based on numbers you tell a lender. A pre-approval is the stronger one: the lender verifies your income, debts, and credit, then confirms a specific amount in writing. Before you make an offer in Ontario, you want a pre-approval.
The two terms sound alike, so it is easy to mix them up. The difference matters, though, because one is a guess and the other is a commitment your lender has actually checked. Here is how they compare and which one you need at each step.
What is a mortgage pre-qualification?
A pre-qualification is the first, lightest step. You share a rough picture of your finances, such as your income, your savings, and your monthly debts, and a lender gives you a ballpark of what you could likely borrow.
Nothing is verified. The lender takes your numbers at face value and often does not pull your credit or ask for documents. It can happen in a few minutes online or over the phone.
That makes a pre-qualification useful early on. It helps you get a rough sense of your price range before you spend weekends touring homes. Just remember the figure can change once a lender looks at the real paperwork.
What is a mortgage pre-approval?
A pre-approval goes much deeper. The lender reviews your actual documents, pulls your credit, and confirms a specific loan amount, usually with a rate held for a set window (often 90 to 120 days).
To get one, you typically provide:
Proof of income, such as pay stubs, a letter of employment, or notices of assessment
Recent bank or investment statements showing your down payment savings
A list of your debts and monthly obligations
Consent for the lender to check your credit
Because a lender has verified the details, a pre-approval tells you a real, reliable budget. It also signals to sellers that a lender has already looked at your finances and is prepared to lend. Learn the full process in our guide on how to get pre-approved for a mortgage in Ontario.
Keep in mind a pre-approval is not a final loan guarantee. The lender still confirms everything again once you have an accepted offer on a specific property, and the home itself must appraise and meet the lender's conditions.

Which one is stronger?
A pre-approval is clearly stronger. It is built on documents a lender has verified, not just numbers you stated, so both you and any seller can trust it.
In a competitive situation, this matters. When a seller receives your offer on the Agreement of Purchase and Sale (OREA Form 100), their agent will look at whether your financing is solid. An offer backed by a pre-approval reads as serious and ready. An offer backed only by a pre-qualification can look uncertain.

Which one do you actually need before making an offer?
You need a pre-approval before you make an offer. A pre-qualification is fine for the very first stretch, when you are just testing your price range and browsing listings for fun.
Once you are seriously shopping and ready to write an offer, the pre-approval does three things for you:
It confirms a real budget so you never fall for a home you cannot finance.
It lets you move fast, which matters when a good listing draws interest.
It strengthens your offer in the seller's eyes.
Homes in many GTA municipalities can move quickly, so having your pre-approval ready before you find "the one" keeps you from missing out while you scramble for paperwork.
How this fits with your down payment
Your pre-approval and your down payment work together. In Ontario, the minimum down payment is 5% on the first $500,000 of the price, 10% on the portion from $500,000 to $1,500,000, and 20% above $1,500,000. On an $800,000 home, that is $55,000 minimum.
With less than 20% down, mortgage default insurance is required and the premium is added to your mortgage. Programs like the FHSA (up to $8,000 a year, $40,000 lifetime) and the RRSP Home Buyers' Plan (up to $60,000) can help you build that down payment faster.

Frequently asked questions
Does a pre-qualification hurt my credit score?
Usually not. A pre-qualification often relies on a soft check or no credit check at all, so it typically does not affect your score. A pre-approval involves a full credit check, which can cause a small, temporary dip. Shopping several lenders in a short window is generally treated as one inquiry.
How long does a pre-approval last?
Most pre-approvals are valid for a set window, commonly 90 to 120 days, and the lender may hold a rate for you during that time. If your window runs out before you buy, you can usually renew it by providing updated documents. Ask your lender for their exact terms.
Can my pre-approval amount change later?
Yes. A pre-approval is based on your finances at the time and still comes with conditions. If your income, debts, or credit change, or if the home does not appraise or meet the lender's requirements, the final amount can shift. Avoid big new purchases or loans while you shop.
Is a pre-approval a guarantee I will get the mortgage?
No. It is a strong, verified signal, but the lender confirms everything again once you have an accepted offer on a specific home. The property must appraise and satisfy the lender's conditions. Keep your finances steady between your pre-approval and closing to avoid surprises.
Do I need a pre-approval just to look at homes?
Not for casual browsing. A quick pre-qualification is enough to set a rough budget while you explore listings. Once you are ready to attend showings with intent and make offers, get a pre-approval so you know your real number and can act quickly.
Which should I get first?
Start with a pre-qualification if you want a fast, no-pressure estimate. Then get a pre-approval before you shop seriously. Many buyers skip straight to the pre-approval, since it gives you a reliable budget and the standing to make a strong offer without redoing the work later.
