Mortgage pre-approval is one of the first concrete steps in buying a home in the GTA. A pre-approval is a formal commitment from a lender stating they will lend you up to a specific amount, at a specific rate, for a specific term — subject to the property meeting their standards and your financial situation remaining unchanged. Without it, you're searching for homes without knowing what you can actually afford, and sellers won't take your offers seriously. This guide walks through exactly how to get mortgage pre-approval in Canada, what documents you need, how the stress test works, and how to choose between a broker and going directly to your bank.
Pre-approval is different from a rate quote or an online mortgage calculator estimate. Those tools give you rough guidance. A pre-approval involves a full credit pull, income verification, and a formal commitment letter — the kind sellers and their agents recognize as a real signal that you're a qualified buyer ready to act. For context on the full purchase timeline, see the steps to buying a home in the GTA.
What Documents You Need for Pre-Approval
Lenders need to verify your identity, income, assets, and debts. Gather these before you start:
| Document category | What to provide |
|---|---|
| Identity | Two government-issued photo IDs; Social Insurance Number |
| Income (employed) | Last 2 T4 slips, 2 recent pay stubs, letter of employment |
| Tax history | Last 2 years' Notices of Assessment (NOA) from CRA |
| Down payment | 90 days of bank statements showing accumulated funds |
| Debts | Statements for all credit cards, loans, and lines of credit |

The Stress Test
Every Canadian mortgage applicant must pass the federal mortgage stress test, regardless of down payment size. The stress test qualifies you at the higher of:
- Your contracted interest rate plus 2%, or
- 5.25% (the regulatory floor)
If your lender is offering a 5-year fixed rate of 4.5%, you'll be stress-tested at 6.5%. This means the lender calculates your GDS and TDS ratios — the percentages of your gross income going to housing costs and total debt — based on the higher qualifying rate, not the actual rate you'll pay. The stress test typically reduces a buyer's maximum purchase price by approximately 15–20% compared to what the actual payment would support.
The CMHC mortgage qualifier tool can help you estimate how the stress test affects your maximum purchase price before you apply.
GDS and TDS Ratios
Lenders calculate two debt ratios:
- GDS (Gross Debt Service ratio): The percentage of gross monthly income going to housing costs (mortgage payment, property tax, heating, and 50% of condo fees if applicable). Maximum: 39% for most lenders.
- TDS (Total Debt Service ratio): GDS plus all other monthly debt obligations (car loans, credit cards, student loans). Maximum: 44% for most lenders.
If your existing debts are high, they reduce how much mortgage you qualify for. Paying down a car loan or line of credit before applying can meaningfully increase your maximum pre-approval amount.
Mortgage Broker vs. Bank
You can apply for pre-approval through your own bank or through a mortgage broker. The differences:
| Bank directly | Mortgage broker | |
|---|---|---|
| Lenders accessed | One | 30+ lenders |
| Rate comparison | Only their own products | Multiple lenders compared simultaneously |
| Cost to buyer | Free | Free (broker paid by lender) |
| Credit bureau impact | One hard pull | Multiple lenders accessed with one pull (soft pulls for rate shopping) |
| Best for | Long-standing banking relationship with strong terms | First-time buyers, self-employed, or anyone wanting to compare rates |
Mortgage brokers are compensated by the lender when your mortgage funds — their service costs you nothing as the borrower. They can access products from banks, credit unions, monoline lenders, and alternative lenders that aren't available directly to the public. For most first-time GTA buyers, a broker is the better starting point.
Rate Hold
Most pre-approvals come with a rate hold — the lender guarantees the offered rate for the duration of the pre-approval period, typically 90–120 days. If rates rise before you buy, your rate hold protects you. If rates fall, you can generally access the lower rate. Getting a pre-approval during a rising rate environment protects your purchasing power.
Pre-Approval vs. Pre-Qualification
A pre-qualification is an informal estimate based on self-reported information — no credit pull, no income verification, no formal commitment. It's useful for rough budgeting but carries no weight with sellers. A pre-approval involves a full credit pull, document submission, and a formal commitment letter from the lender. When you're ready to make offers in the GTA, you need a pre-approval — not a pre-qualification.

FAQ
How long does mortgage pre-approval take in Canada?
With a mortgage broker and complete documentation, pre-approval typically takes 1–3 business days. Banks may take 3–7 business days. The timeline depends on how quickly you can submit your documents and how complex your income situation is. Self-employed buyers typically take longer due to additional documentation requirements.
Does mortgage pre-approval hurt your credit score?
A pre-approval requires a hard credit pull, which temporarily reduces your credit score by a few points. Multiple hard pulls from different lenders within a 14–45 day window are typically treated as a single inquiry by credit bureaus for mortgage-shopping purposes. One or two mortgage inquiries will not significantly affect your ability to qualify.
Can I get pre-approved for a mortgage with a low credit score?
Most major banks and A-lenders require a minimum credit score of 680 for their standard mortgage products. A score below 680 may still qualify through alternative (B) lenders like Home Trust or Equitable Bank, typically at slightly higher rates. A mortgage broker can advise on which lenders are most suitable for your credit profile.
Do I need to be pre-approved before making an offer?
Not legally, but practically yes. In the GTA, sellers and listing agents expect buyers to have financing arranged before making offers. Some sellers will not accept offers from buyers without pre-approval. Even if a seller accepts your offer with a financing condition, the conditional period (typically 5 business days) is very short — far too short to start the pre-approval process from scratch.
What is the maximum mortgage I can get in Canada?
Your maximum mortgage depends on your gross income, existing debts, down payment, and the stress test qualifying rate. As a rough guide, most buyers qualify for approximately 4–5 times their gross annual income, though the exact amount varies by lender, rate, and debt load. Use a mortgage broker to get an accurate pre-approval amount based on your specific situation rather than relying on online calculators.
