A mortgage pre-approval confirms how much a lender will advance, locks in an interest rate for 90 to 120 days, and shows sellers that a buyer is serious and financially ready. Getting one before house hunting is one of the most important steps a buyer can take in Ottawa’s market.
Pre-approval is different from a quick pre-qualification. It involves the lender actually verifying income, credit and down payment, so it carries real weight when it is time to make an offer.

What Is Mortgage Pre-Approval?
Pre-approval is a conditional commitment from a lender confirming the maximum mortgage a buyer qualifies for, based on a full review of their finances. The lender verifies income, checks credit and assesses the down payment before issuing a letter with a locked rate.
That rate hold, typically 90 to 120 days, protects the buyer if rates rise during the search, and most lenders honour a lower rate if rates fall before closing. It is a meaningful advantage in a changing market.
Pre-qualification is different and weaker. It is only a rough estimate based on self-reported numbers, so sellers and agents give it little weight. Serious buyers get a full pre-approval.
Why Pre-Approval Matters in Ottawa
Pre-approval gives a buyer three advantages. It confirms a realistic budget, strengthens every offer, and lets the buyer act quickly when the right home appears.
In competitive west-end communities like Kanata, Stittsville and Barrhaven, well-priced homes can attract multiple offers quickly, and an offer without pre-approval is at a real disadvantage. Sellers treat a pre-approval as confirmation that financing will not derail the deal.
Just as importantly, knowing the true budget keeps the search focused and prevents falling for homes that are out of reach. Current price context by area is published monthly by the Ottawa Real Estate Board.

The Mortgage Stress Test
Every buyer using a federally regulated lender must pass the mortgage stress test before receiving a commitment, including pre-approval. The test ensures a borrower could still afford payments if rates rose.
Buyers must qualify at the higher of their contract rate plus two percentage points or the 5.25% minimum qualifying rate, a rule set by the Office of the Superintendent of Financial Institutions under Guideline B-20. So a buyer who offered 4.5% must show they can afford payments at 6.5%.
Lenders also apply two debt-service ratios, calculated at the stress-tested rate rather than the actual rate.
| Ratio | What it measures | Typical maximum |
|---|---|---|
| Gross debt service (GDS) | Housing costs ÷ gross income | About 39% |
| Total debt service (TDS) | All debts ÷ gross income | About 44% |
Gross debt service includes the mortgage payment, property tax, heating and half of any condo fees, while total debt service adds all other monthly debts such as car loans and credit cards. Some lenders apply stricter limits than these guidelines.

Documents Needed for Pre-Approval
Having documents ready speeds up pre-approval, and many straightforward applications are assessed within a few business days. Lenders verify three things: income, down payment and credit.
- Proof of income: recent pay stubs, an employment letter, and the last two years of T4s and Notices of Assessment; self-employed buyers provide two years of T1 returns and financial statements
- Proof of down payment: about 90 days of account statements showing the source, including savings, investments, or an FHSA or RRSP withdrawal, plus a signed gift letter if funds are gifted
- Credit: the lender pulls a credit report as part of the review
The Canada Revenue Agency is the source for T4s and Notices of Assessment, and a mortgage broker can review a file in advance to smooth the process.
Credit Score and Pre-Approval
Credit is central to pre-approval. Insured mortgages generally require a minimum score around 600 for at least one borrower, while a score of about 680 or higher helps secure the best rates.
A pre-approval involves a hard credit inquiry, but rate shopping is protected: multiple mortgage inquiries within a short window, generally 14 to 45 days, are treated as a single inquiry, so the score impact is minimal. Guidance on credit is available from the Financial Consumer Agency of Canada.
Paying down balances and avoiding new cre
How Much Can a Buyer Afford?
A pre-approved amount is a ceiling, not a target. Borrowing the maximum leaves no cushion for closing costs, rate changes or the unexpected, which is a common source of financial stress.
The Financial Consumer Agency of Canada suggests keeping total housing costs, including mortgage, taxes, utilities and upkeep, within about 35% of gross household income. Buying below the maximum is usually the wiser choice.
The right budget also depends on the down payment. Jason’s guide on how much is needed for a down payment explains the tiers, and a down payment under 20% requires mortgage default insurance from a provider such as the Canada Mortgage and Housing Corporation.
How to Strengthen a Pre-Approval
A few steps improve both the amount a buyer qualifies for and the rate offered. Each addresses a factor lenders weigh.
Reducing existing debt lifts the total debt service ratio, since every monthly payment reduces borrowing room. Improving credit by keeping card balances low and avoiding new applications helps the rate, and a stable income history reassures lenders.
A larger down payment also helps, both by improving the ratios and, at 20% or more, by removing mortgage default insurance. Confirming financing through a licensed broker, such as members of the Canadian Mortgage Brokers Association of Ontario, can open up options and better rates.
After Pre-Approval: Next Steps
A pre-approval gives the search structure, but a few things are worth remembering. The rate hold lasts 90 to 120 days, and a longer search may require a renewal with updated documents.
Pre-approval is not final approval. The lender still assesses the specific property, including an appraisal, before issuing the mortgage commitment, which is why a firm offer still carries some risk if the appraisal comes in low.
Buyers should also budget for closing costs of roughly 1.5% to 4% of the price, and interest-rate movements are worth watching through the Bank of Canada. With pre-approval in hand, the next step is finding the right home.
