Mortgage Pre-Approval in Ontario — What You Need to Know
Before you tour a single home in Toronto, Mississauga, or anywhere in the GTA, get pre-approved. It's the single most important step in the home buying process — and it takes less time than you think.
Book a Buyer ConsultationWhy Pre-Approval Is Non-Negotiable in the GTA
The GTA real estate market moves fast. Sellers in Toronto, Oakville, and Burlington often review multiple offers within days. Here's why pre-approval is your most important first move.
Know Your Real Budget
Pre-approval gives you a firm number to shop with — not a guess. You'll know the maximum purchase price and monthly payment you qualify for before wasting time on homes you can't afford.
Lock Your Rate
Most lenders hold your pre-approved rate for 90–120 days. If rates rise before you buy, you're protected. If rates fall, you get the lower rate.
Compete With Serious Buyers
In the GTA, sellers often won't entertain offers without proof of financing. A pre-approval letter signals you're a committed, qualified buyer.
Speed Up Closing
With pre-approval done upfront, final mortgage approval moves faster once your offer is accepted — reducing the risk of financing conditions killing your deal.
Understanding the Mortgage Stress Test
Since 2018, federally regulated lenders in Ontario must qualify buyers at the stress test rate — which is the greater of:
In practice, this means a buyer with $100,000 gross income might qualify for approximately $500,000–$550,000 in mortgage financing — depending on debts, down payment, and lender. The stress test reduces your maximum buying power by roughly 20% compared to qualifying at your actual contract rate.
Credit unions and alternative lenders are not always subject to the federal stress test, which is why working with a mortgage broker who accesses multiple lender types can sometimes unlock more buying power.
Documents You'll Need
Gathering these before your first lender meeting will speed up the process significantly.
Government-issued photo ID (passport or driver's license)
Proof of income: recent pay stubs, T4s, or 2 years of Notice of Assessment (self-employed)
Employment letter confirming position, salary, and employment start date
Last 90 days of bank statements for down payment verification
Proof of down payment source (savings, RRSP, gift letter, etc.)
List of current debts: credit cards, car loans, student loans
Social Insurance Number (SIN) for credit check authorization
Mortgage Pre-Approval FAQ
Common questions from GTA buyers about the pre-approval process.
What's the difference between pre-qualification and pre-approval?
Pre-qualification is an informal estimate based on self-reported income and debts — it has no weight with sellers. Pre-approval is a formal lender review with verified documents and a credit check. In the GTA market, only pre-approval matters. Always get pre-approved before you start seriously shopping.
Does getting pre-approved hurt my credit score?
A mortgage pre-approval involves a "hard inquiry" which may temporarily lower your credit score by a few points. However, if you're shopping multiple lenders within 14–45 days, credit bureaus typically treat all mortgage inquiries as a single inquiry, minimizing the impact.
How much mortgage can I qualify for in Ontario?
Federally regulated lenders use the stress test, qualifying you at the greater of 5.25% or your contract rate plus 2%. Generally, your total debt service (TDS) ratio must stay under 44% and your gross debt service (GDS) ratio under 39% of gross income. A broker or lender can calculate your exact limit.
Should I use a bank or a mortgage broker?
Both have merit. Banks offer convenience and loyalty discounts. Mortgage brokers shop 30–50+ lenders to find the best rate and terms for your specific situation — and their service is free (lenders pay them). I recommend getting quotes from both before deciding.
What is CMHC mortgage insurance and when do I need it?
If your down payment is less than 20%, your mortgage must be insured through CMHC, Sagen, or Canada Guaranty. The premium ranges from 2.8%–4% of the mortgage amount and is added to your mortgage. It protects the lender — not you — but it allows you to buy with as little as 5% down.
