Notice of Assessment for a Mortgage in Canada (2026): What Lenders Need and Why

You found the home. Your realtor is ready. And the mortgage broker just asked you to send over your Notice of Assessment — maybe two of them.

If you are not sure what that is, where to find it, or why a bank needs it before approving your mortgage, you are not alone. This is one of the most common document questions in Canadian home buying — and getting it right can mean the difference between a smooth approval and a frustrating delay.

This guide explains exactly what lenders need from your NOA, why it matters more than your T4, and what to do if yours shows a balance owing, is outdated, or you simply cannot find it.

Quick Answer: Canadian mortgage lenders use your Notice of Assessment to verify your declared income, confirm you have no outstanding CRA debt (which takes priority over any lender), and calculate your debt service ratios. Most lenders want the 2 most recent years. Get yours instantly through CRA My Account — it is the fastest and most reliable source.

Why Lenders Ask for Your Notice of Assessment

Your NOA serves three specific purposes in a mortgage application — and each one matters to your approval:

1. Income Verification

The NOA shows your net income (Line 23600) as officially assessed by the Canada Revenue Agency. This is the number lenders use to calculate how much mortgage you can qualify for.

Your pay stubs show what you earn now. Your T4 shows what you earned last year. Your NOA shows what the government confirmed you earned after assessing your tax return — and that distinction matters. If your pay stub says $95,000 but your NOA says $62,000 (because of significant business expense deductions), the lender qualifies you on $62,000.

This is especially important for self-employed Canadians. A mortgage broker or bank verifying employment income for a salaried employee mostly relies on pay stubs and a T4. For self-employed borrowers, the NOA is often the primary income document — because it reflects what was actually declared and accepted by the CRA.

2. Confirming No Outstanding CRA Debt

Federal tax debt is a super-priority lien in Canada. This means if you owe the CRA money, the government's claim on your assets takes precedence over your mortgage lender's claim. A lender who approves your mortgage without checking for CRA debt is taking on risk they do not know about.

Your NOA shows whether you had a balance owing. If you paid it, the account balance is zero. If you did not pay it, it shows as outstanding — and lenders will want to understand the situation before approving your mortgage.

A CRA balance owing does not automatically disqualify you from a mortgage — but it will be scrutinized, and you may need to show it has been paid or is being paid under an arrangement.

3. Calculating Debt Service Ratios

Lenders calculate two ratios to determine how much mortgage you can carry:

• Gross Debt Service (GDS) ratio: Housing costs (mortgage payments, property taxes, heating, half of condo fees) as a percentage of gross income. Maximum: 39%
• Total Debt Service (TDS) ratio: All debt payments (housing + car loans, credit cards, student loans, other debts) as a percentage of gross income. Maximum: 44%

The income in both formulas comes from your NOA — specifically Line 23600. The higher your declared income, the higher the mortgage you can qualify for. This is the fundamental reason self-employed Canadians who aggressively minimize taxable income on their NOA often qualify for a smaller mortgage than their actual cash flow would suggest.

How Many Years of NOAs Do Lenders Need?

The standard across most major Canadian lenders — RBC, TD, BMO, Scotiabank, CIBC, and most credit unions — is 2 consecutive years of NOAs. Some lenders require 3 years for self-employed borrowers or when income has been inconsistent.

Which Line on Your NOA Matters for a Mortgage

Lenders focus on specific lines of your NOA when calculating your qualifying income. Knowing which lines matter helps you understand how a lender sees your financial picture.

Self-employed note: Lenders typically use a 2-year average of Line 23600 when income varies year to year. If Year 1 shows $70,000 and Year 2 shows $90,000, most lenders qualify you on $80,000 — not $90,000.

Where to Get Your NOA for a Mortgage Application

As of February 2026, the CRA no longer mails NOAs automatically. Here are your options to get them quickly for a mortgage application:

Option 1 — CRA My Account (Fastest — Recommended)

1. Go to canada.ca/my-cra-account and sign in
2. Select Tax returns from the menu
3. Choose View past returns and select the tax year
4. Select Notice of Assessment to view and download as a PDF
5. Repeat for each year required by your lender

Your NOA is available the moment the CRA processes your return — typically within 2 weeks of filing electronically. You can print or email the PDF directly to your mortgage broker.

Option 2 — Through Your Tax Software

If you used NETFILE-certified software (TurboTax, Wealthsimple Tax, H&R Block), your NOA is typically available directly within the app once issued. Check under "My returns" or "Filed returns" for the relevant year.

Option 3 — By Phone (Slowest)

Call the CRA at 1-800-959-8281 and request a paper copy. This takes 5–10 business days to arrive by mail — not ideal if your mortgage closing has a deadline. Always use CRA My Account if possible.

Important: Lenders want the official CRA document — not a summary or screenshot. Download the full PDF from CRA My Account and provide that to your broker.

What If Your NOA Shows a Balance Owing?

A balance owing on your NOA does not automatically disqualify you from a mortgage — but it will be flagged and you need to address it proactively.

Here is how lenders typically handle a NOA with a balance owing:

• Paid in full: If the balance was paid, your CRA account shows a zero balance. Some lenders will ask for a CRA account statement confirming it is paid. Log into CRA My Account and print your account summary.
• On a payment arrangement: Lenders treat the monthly payment obligation as a liability in your TDS ratio. You will need to disclose the arrangement and the monthly payment amount.
• Unpaid and unaddressed: This is the most challenging scenario. Lenders may decline the application until the CRA debt is resolved, or may require it to be paid at closing from the proceeds of the mortgage (on refinances). The super-priority status of CRA debt means lenders cannot safely ignore it.

If you have an outstanding CRA balance and are planning to apply for a mortgage, address it before you apply — even setting up a payment arrangement and having one or two payments made on record strengthens your position significantly.

What If You Do Not Have 2 Years of NOAs?

There are several situations where 2 years of NOAs are not available:

Newcomers to Canada

If you recently arrived in Canada and have filed only one return (or none yet), most major banks have newcomer mortgage programs that accept alternative income documentation — international credit history, employment letters, and bank statements. Some lenders only require your most recent available NOA plus additional employment verification.

First-Time Filers

If you have never filed a Canadian tax return and are applying for a mortgage, file immediately. Lenders cannot process most mortgage applications without at least one NOA. Filing your first return and receiving your NOA can often be done within 2–4 weeks if you file electronically.

Self-Employed with Less Than 2 Years of Business History

Most prime lenders require 2 years of self-employment history before they will use self-employment income for qualifying. If you have been self-employed less than 2 years, you may need to apply through an alternative or B-lender program, or use a co-borrower with traditional employment income.

Recent Career Change or Gap in Filing

If you have an unfiled year, file it immediately — even retroactively. Lenders will identify gaps in your tax history and may ask to see all years. Unfiled returns can also indicate outstanding CRA debt, which lenders will flag.

The NOA and the Mortgage Stress Test (2026)

All Canadian mortgage applications are subject to the federal mortgage stress test, administered by OSFI. In 2026, the qualifying rate is the higher of your contract rate plus 2% or 5.25%.

The stress test is calculated on the income shown on your NOA. Here is a practical example of how your NOA income affects what you can borrow:

Estimates based on 39% GDS ratio, $250/month in property taxes and heating, no other debt. Actual qualification depends on full debt picture, credit score, and down payment.

This table illustrates why your NOA income — not your gross earnings — directly determines how much house you can buy. For self-employed Canadians, this is the clearest argument for managing tax deductions strategically rather than minimizing taxable income as aggressively as possible.

Future Change: CRA Income Verification Tool for Mortgages

Following Budget 2024 consultations, the CRA is actively developing a direct income verification tool for the mortgage industry. Once implemented, lenders may be able to verify your income directly with the CRA — with your consent — rather than relying on paper NOAs.

This would speed up mortgage approvals significantly and reduce fraud risk. As of April 2026, the tool is still in development. For now, the NOA PDF from CRA My Account remains the standard verification method.

Frequently Asked Questions

Why do mortgage lenders in Canada need my Notice of Assessment?

Lenders use your NOA for three reasons: to verify the income you declared on your tax return matches what you are claiming on your mortgage application, to confirm you have no outstanding CRA debt (which holds super-priority over any lender's claim), and to calculate your Gross Debt Service and Total Debt Service ratios using your official net income from Line 23600.

How many years of NOAs do I need for a mortgage in Canada?

Most Canadian lenders require the 2 most recent consecutive years of NOAs. Self-employed borrowers and those with variable income may be asked for 3 years. Newcomers to Canada with limited CRA history may qualify with just 1 year plus alternative documentation like international credit history and employment letters.

Which line on my NOA do lenders use for income?

The primary income figure most lenders use is Line 23600 — Net Income. This is your income after most deductions but before certain final adjustments. For self-employed borrowers with two years of returns, lenders typically use a 2-year average of this line.

How do I get my NOA for a mortgage application?

The fastest way is through CRA My Account at canada.ca/my-cra-account. Go to Tax returns → View past returns → Select the year → Download the NOA as a PDF. You can access every NOA you have ever received this way. As of February 2026, the CRA no longer mails NOAs automatically — My Account is the primary source.

Can I still get a mortgage if my NOA shows a balance owing?

Yes — but the outstanding debt will be scrutinized. If the balance has been paid, provide a CRA account statement showing a zero balance. If it is on a payment arrangement, lenders will include the monthly payment in your TDS calculation. If it is unpaid and unaddressed, lenders may require it to be resolved before or at closing. Address any CRA debt before applying for a mortgage.

I am self-employed. How does my NOA affect my mortgage qualification?

For self-employed borrowers, the NOA is the primary income verification document. Lenders use Line 23600 (net income after deductions) — which means the more expenses you deduct, the lower your qualifying income. This is a fundamental tension for self-employed Canadians: aggressive tax minimization reduces your tax bill but also reduces the mortgage you can qualify for. Discuss your strategy with a mortgage broker before filing if a home purchase is planned.

What if I only have one year of NOA — I just moved to Canada?

Most major Canadian banks offer newcomer mortgage programs that accommodate limited Canadian tax history. These typically require your most recent available NOA (if any), an employment letter confirming your position and income, 6 months of Canadian bank statements, and sometimes international credit bureau documentation. Speak with a mortgage broker familiar with newcomer programs.

My NOA shows the wrong income because the CRA made changes to my return. What do I do?

If the CRA made changes you disagree with, file a T1 Adjustment through CRA My Account or a Notice of Objection within 90 days of your assessment date. If you agree with the changes but they reduce your qualifying income, be transparent with your lender and provide full documentation. Attempting to use an older NOA that shows higher income while hiding a more recent reassessment is considered mortgage fraud.

How old can my NOA be when applying for a mortgage?

Most lenders want NOAs that are recent — typically from the current or immediately prior tax year. An NOA from 3+ years ago may not be accepted as current income verification. If you have not filed recently, file immediately. The sooner you file, the sooner you get an updated NOA. Tax returns for prior years can be filed retroactively through CRA My Account.

Will the CRA eventually verify my income directly with mortgage lenders?

The CRA is actively developing an income verification tool for the mortgage industry following Budget 2024 consultations. When implemented, lenders would be able to verify your income directly with the CRA — with your consent — rather than relying on paper NOAs. As of April 2026, this tool is still in development. The NOA PDF from CRA My Account remains the standard method for now.
