How to Get a Mortgage Pre-Approval in Canada

A mortgage pre-approval is a lender's written estimate of how much it may lend you and at what rate, based on a review of your income, debts, and credit. It is not a guarantee, but it gives you a budget to shop with and usually holds a rate for a set period. Here is how to get a mortgage pre-approval in Canada, step by step.

What a pre-approval actually gives you

A pre-approval tells you the maximum a lender is prepared to consider and often locks a rate for a short window, so you are protected if rates rise while you house-hunt. It does not promise funds. The lender still has to verify your documents, appraise the property, and confirm everything at the time of the real application.

That distinction matters when you make an offer. A seller wants to know you are credible, and a pre-approval letter helps, but your financing condition still depends on final approval. Treat the pre-approval as a strong starting point, not a done deal.

Do not confuse a pre-approval with a pre-qualification. A pre-qualification is usually a quick, informal estimate based on the numbers you supply, often without a full credit review. A pre-approval involves a real credit check and a document review, so it carries more weight with sellers and gives you a more reliable figure.

Step-by-step: from documents to a rate hold

1. Check your credit report and score, and fix any errors before a lender sees it.
2. Gather your identification, income proof, down payment evidence, and debt details.
3. Decide whether to use a bank, credit union, or mortgage broker who can compare lenders.
4. Submit the application and let the lender pull your credit and assess your file.
5. Review the pre-approval amount, rate, rate hold period, and conditions in writing.
6. Shop for a home within the budget, keeping the rate hold deadline in mind.
7. Return to the lender with the property details for final approval before you waive conditions.

Each step builds on the last. Skipping the credit check or the document gathering is the most common reason a pre-approval turns out to be lower than expected. If you are self-employed, the self-employed mortgage guide explains the extra income proof you will need.

It also helps to know your budget before you talk to a lender. Use the mortgage affordability calculator to see what a given payment does to your monthly cash flow, then compare that with the pre-approval amount. The two numbers are not the same thing, and the lower one should guide your search.

What to bring to the appointment

• Identification — government photo ID and proof of your status in Canada if you are not a citizen.
• Income proof — recent pay stubs, an employment letter, and often notices of assessment from the Canada Revenue Agency.
• Down payment — recent bank and investment statements showing the funds and their source.
• Debts — credit card balances and limits, car loans or leases, lines of credit, student loans, and support payments.
• Assets — other accounts, vehicles, or property that support your file.

The full inventory is covered in the documents needed for a mortgage application. Having everything ready speeds up the process and reduces the chance the lender comes back with conditions you did not expect.

If any document is missing, say so up front. A lender who knows about a gap can suggest an alternative; a lender who discovers it later may view the file very differently. Honesty early is almost always faster than a surprise at the end.

How long a pre-approval lasts

Rate holds commonly last for a set number of days, often measured in months, and the exact window is set by the lender. Confirm the expiry date in writing, because a hold that lapses leaves you exposed to whatever rates are then available. Some lenders let you extend the hold for a fee, and some will match a lower rate if rates fall during the hold period.

If your search runs longer than the hold, ask about an extension before it expires rather than after. It is usually easier to negotiate while you are still a prospective borrower than after the deadline has passed.

Compare holds across lenders as carefully as you compare rates. A slightly higher rate with a longer hold can be worth more than a lower rate that expires in a few weeks, especially in a market where homes sell quickly.

Pitfalls that derail a pre-approval

1. Changing jobs, income, or your debt load after the pre-approval and before closing.
2. Applying for new credit, such as a car loan or a new credit card, while the file is open.
3. Making a large unexplained deposit into your down payment account without documenting its source.
4. Assuming the pre-approval amount is guaranteed for any property, including one the lender will not accept.
5. Letting the rate hold expire while you keep shopping.

Lenders re-check your file before funding. A pre-approval that looked fine can fall apart if your circumstances change, so keep your finances steady until the mortgage is in place. A short period of stability is a small price for a smoother closing.

Another quiet pitfall is assuming the pre-approval covers any property. Lenders decline certain property types, locations, or buildings with issues, so confirm the property will be acceptable before you make a firm offer.

After pre-approval: shopping with confidence

With a pre-approval in hand, you can shop with a realistic ceiling and make a cleaner offer. Use the number as a guide, not a target, and test how the payment would feel with the affordability calculator. The GDS and TDS ratios show how the lender reached your number, and the mortgage stress test explains why you qualify for less than the raw math might suggest. You can also estimate your tested payment with the stress test calculator. Confirm all current figures and hold periods with your lender before you commit.
