Stress test for mortgage in Canada

Buying your own home is one of the main goals for many Canadians after finishing their studies and starting work. Homeownership is considered an important part of the "Canadian dream." However, beyond saving money for a down payment, there's another important aspect that not all buyers know about — the mortgage stress test.

Against the backdrop of significant changes in mortgage regulation that occurred in 2024-2025, the stress test has once again become the center of public debate. The removal of stress test requirements for certain categories of borrowers in November 2024 and the introduction of new loan-to-income (LTI) restrictions in early 2025 mark the beginning of a major reform of the mortgage lending system. The decisions that OSFI makes in 2026 could drastically change the rules of the game for all real estate market participants.

What is the mortgage stress test?

The mortgage stress test in Canada is a tool used to assess whether a borrower can continue making mortgage payments in case of financial difficulties, job loss, or rising interest rates. This test is mandatory before mortgage approval and helps reduce risks for both borrowers and lenders.

The essence of the stress test is for banks to assess how resilient a borrower is to possible interest rate fluctuations. To pass the test, you need to prove that the borrower can afford mortgage payments at a rate of 5.25% or their contract rate plus 2%, whichever is higher.

For example, if your contract rate is 3.5%, you'll be tested at 5.5% (3.5% + 2%). But if your contract rate is 4.5%, then the test will be at 6.5% (4.5% + 2%), since this is higher than the minimum threshold of 5.25%. It's important to understand that this qualifying rate is only used to assess your ability to pay, not to calculate your actual payments.

To determine if you can pass the stress test and get a home mortgage, use the Mortgage Qualifier Tool from the official website of the Financial Consumer Agency of Canada (FCAC). This calculator will help you assess whether your income and expenses meet the requirements for getting a mortgage.

Impact of the stress test on the real estate market

The introduction of the stress test has noticeably reduced the purchasing power of many potential homebuyers in Canada. Due to qualification at a higher rate, many borrowers may get a smaller loan amount. For example, if you could previously get a mortgage for $750,000 at a fixed rate of 2.75% over 25 years, qualifying at a rate of 5.25% could reduce the maximum loan amount by about 20%, significantly decreasing the available sum.

However, important changes occurred in the rules starting November 21, 2024. OSFI (Office of the Superintendent of Financial Institutions) eliminated the minimum qualifying rate (MQR) requirement for so-called straight switches — transfers of uninsured mortgages between federally regulated lenders. This exemption only applies when strict conditions are met: the loan amount doesn't increase, the amortization period remains the same or decreases, and other contract terms don't change. This simplified the process of switching lenders for property owners with a 20% or higher down payment who are looking for better interest rates.

Key terms: what's important to know

To understand mortgage lending rules, it's helpful to understand the basic terms:

• MQR (Minimum Qualifying Rate) — the minimum qualifying rate used for the stress test. As of October 2025, this is 5.25% or the contract rate plus 2%, whichever is higher. MQR is set and periodically reviewed by OSFI depending on economic conditions and may be changed in the future.
• LTI (Loan-to-Income) — the ratio of loan amount to the borrower's annual income. For example, if your mortgage is $450,000 and your annual income is $100,000, your LTI is 4.5.
• Uninsured mortgage — a loan with a 20% or higher down payment that doesn't require mandatory mortgage insurance through CMHC or other insurance companies.
• Insured mortgage — a loan with less than 20% down payment that requires default insurance.
• Straight switch — transferring a mortgage to a new lender without changing the loan amount, amortization period, or other key terms.
• Amortization — the total period over which the mortgage is planned to be fully paid off (usually 25 or 30 years).

There are credit unions and other lenders that may provide loans without requiring a stress test. Since many credit unions are regulated provincially rather than federally, OSFI's stress test requirements don't apply to them. However, before turning to such organizations, it's worth considering several important points.

• The absence of a stress test allows you to get a larger loan than through federal banks. This can be especially useful for those who can't pass the stress test but still want to buy a home.
• However, keep in mind that such lenders may offer higher interest rates — the difference is usually 0.5% to 1% compared to major banks. Lending terms at these organizations may be less flexible, and borrower protection may be less reliable.
• Additionally, such lenders may be less protected by government guarantees in case of economic problems, which increases risks for borrowers.
• Alternative and private lenders may also offer financing without a stress test, but their interest rates are often significantly higher — sometimes up to 8-10% annually.

This is why many borrowers still choose federal banks despite having to pass the stress test, to get more stable and reliable lending terms with lower interest rates.

Debates around the necessity of the stress test and the new LTI system

The stress test helps reduce the likelihood of mortgage defaults and decreases risks for lenders. However, it complicates the home buying process for many Canadians. In 2025, the question of the stress test's future became particularly relevant.

Starting in the first quarter of 2025, OSFI introduced a new risk control mechanism at the bank portfolio level — loan-to-income (LTI) limits. According to these rules, federal banks are limited in the number of new uninsured mortgages exceeding 4.5 times the borrower's annual gross income. It's important to understand: this restriction applies to each bank's portfolio as a whole, not directly to individual borrowers.

Each bank received an individual limit on the share of such high-risk loans in its portfolio — usually 15% to 25% of new uninsured mortgage originations per quarter. The specific limit for each financial institution is determined by OSFI based on its size, risk profile, and historical lending performance. Banks must report quarterly to OSFI on compliance with established limits.

In practice, this means that if a bank has already issued enough high-LTI mortgages in the current quarter, it may refuse subsequent borrowers with similar ratios or offer them less favorable terms, even if they technically pass the stress test.

OSFI has officially stated that it will evaluate the effectiveness of the LTI-limit system until at least January 2026, after which it will decide whether this system can supplement or completely replace the existing stress test for uninsured mortgages. OSFI's internal analysis showed that the stress test did not prevent the accumulation of mortgages with very high debt-to-income ratios — many borrowers continued to get loans exceeding 450% of their annual income.

Some experts and mortgage industry representatives predict that the complete elimination of the stress test for uninsured mortgages could happen as early as late 2025 or early 2026, if the LTI system proves effective. This would align with international practices: for example, the UK successfully transitioned to an LTI-restriction system, abandoning the stress test.

Arguments for and against the stress test

The debate around the stress test continues, and each side has valid arguments.

Benefits of the stress test:

• Protects borrowers from excessive debt — the test helps ensure people don't borrow more than they can afford
• Reduces systemic risks for the banking sector and the country's financial stability
• Prevents mass defaults when interest rates rise sharply, as happened in 2022-2023
• Cools down overheated real estate markets in major cities

Disadvantages and criticism of the stress test:

• Significantly reduces housing affordability, especially for young families and first-time buyers
• Regional imbalance: in provinces with lower housing prices, the stress test may be unnecessarily strict
• Unfairness during low interest rates: when actual rates are 2-3%, qualifying at 5.25% seems excessive
• The stress test did not prevent the accumulation of high LTI ratios, as OSFI's analysis showed
• Creates artificial barriers for responsible borrowers with good credit history

The mortgage stress test is a precautionary measure that protects both borrowers and the financial system as a whole. However, its impact on housing affordability is causing debate in society, and significant changes in mortgage lending regulation are possible in the coming years.

Impact of the stress test on different population groups

The stress test affects different population groups differently, which is especially important to consider when planning a home purchase.

• Young families and first-time buyers often face the greatest difficulties passing the stress test. Limited financial resources, the need to save for a down payment, and expenses for children complicate the ability to get a mortgage. In major cities like Toronto and Vancouver, where the average home price exceeds $1 million, the stress test effectively excludes many young people from the market. As a result, many young families are forced to delay home purchases for years, rent housing, or consider options in distant suburbs.
• For retirees, the stress test can become a serious obstacle when refinancing a mortgage or buying new housing. Limited income after retirement may not meet stress test requirements, especially if the main income consists of pensions and savings. Even if a retiree owns significant real estate and has excellent credit history, low official income can prevent refinancing. This may force retirees to abandon the idea of improving their housing situation or turn to alternative lenders with higher rates.
• Self-employed individuals and entrepreneurs often face additional complications when passing the stress test. Income instability and seasonality, difficulty in documenting earnings complicate the process. Banks may require two to three years of tax returns, business financial statements, and other documents. Even with good actual income, officially declared income may be lower due to tax deductions and business expenses. This may lead to the need to turn to alternative lenders or increase the down payment.
• Investment property buyers face special rules: potential rental income is usually only partially considered (50-80%), which further reduces their qualifying ability when applying the stress test.

Regional differences and market features

The impact of the stress test varies significantly depending on the region of Canada. In provinces with high real estate prices, such as British Columbia and Ontario, the stress test creates the greatest barriers for buyers. In Vancouver and Toronto, where the average home price can exceed $1-1.5 million, a family needs significant annual income (often more than $200,000) to pass the stress test.

At the same time, in Atlantic provinces, Quebec, or the prairies, where housing prices are significantly lower, the impact of the stress test is less dramatic, although still noticeable for buyers with low and middle income.

Strategies for potential buyers

Those planning to buy housing in Canada should consider the impact of the stress test on mortgage opportunities and use available strategies to increase their chances of approval.

Increasing the down payment remains one of the most effective strategies. The larger the down payment, the smaller the loan needed, which reduces the impact of the stress test on the borrower. If you can put down 20% or more, this also eliminates the need to pay CMHC insurance, which further reduces monthly payments.

Improving your credit score can help significantly. A credit score above 700 (preferably 750 and higher) provides access to the best interest rates. Regular on-time bill payments, reducing credit card usage (preferably below 30% of the limit), and correcting errors in your credit history can improve your score within a few months.

Reducing existing debts before applying for a mortgage is critically important. Banks evaluate your TDS (total debt service) ratio, which includes all your debt obligations. Paying off credit cards, auto loans, or student loans can significantly improve your metrics and increase the available mortgage amount.

Considering a joint application with a spouse or partner combines your incomes, which can substantially increase qualifying ability. However, remember that all debts of both applicants are also considered.

Consulting with a mortgage broker can open access to a broader range of lenders and programs. Brokers work with dozens of lenders, including those that may offer more flexible terms for self-employed individuals, new immigrants, or people with non-standard situations.

For those who cannot pass the stress test at federal banks, turning to provincially regulated credit unions may be a solution. While interest rates may be 0.5-1% higher, they may offer more flexible approval criteria and even 30-year amortization instead of the standard 25 years.

Experts recommend that potential buyers consult with mortgage specialists or financial advisors to better understand the process and assess their opportunities in current market conditions. This is especially relevant in 2025, when the regulatory environment is undergoing significant changes.

What You Need to Know About Mortgage Renewals and Switching Lenders

If you already own property and are planning to renew your mortgage, the situation depends on what you decide to do. When renewing with your current lender, you don't need to pass the stress test — you automatically qualify to renew your contract under new terms.

However, if you want to switch lenders to get a better rate, things became easier starting November 21, 2024, but with some conditions. For uninsured mortgages (those with a down payment of 20% or more), the stress test requirement has been removed for what's called a "straight switch" — meaning when you move to a new lender without increasing your loan amount or extending your amortization period.

This important change gives homeowners more opportunities to shop around for better terms. Experts estimate that about 1.2 million Canadian households need to renew their fixed-rate mortgages in 2025, many of whom originally got their mortgages at rates below 3%. Removing the stress test for straight switches allows them to shop around between lenders, even if their financial situation has changed.

However, it's important to understand: if you want to increase your loan amount (for example, to refinance for other purposes), extend your amortization period, or change other terms, the stress test will still apply in full.

Real Example: How the Stress Test Affects Your Buying Power

Let's look at a concrete example. A family with an annual income of $100,000 wants to buy a house. They have a 20% down payment ($100,000) and need a $400,000 mortgage. The bank offers them a 4% interest rate over 25 years.

Without the stress test, their monthly payment would be about $2,110, which is quite manageable on their income (roughly 25% of gross income).

However, with the stress test, the bank must check if they can afford payments at 6% (4% + 2%). At this rate, the monthly payment would be about $2,565. Add property taxes (about $300 per month) and heating (about $150), and total housing costs reach approximately $3,015 per month.

This works out to about 36% of their gross monthly income, which is within the acceptable GDS ratio (39%). If the family has no other significant debts, they'll pass the stress test. However, if they have a $400 monthly car payment and $200 in minimum credit card payments, their TDS ratio reaches 43%, which is close to the maximum allowable level of 44%.

Now let's consider the LTI impact. With a $400,000 mortgage and $100,000 income, their LTI is 4.0 — below the 4.5 threshold. However, if they wanted a $500,000 mortgage (LTI of 5.0), the bank might refuse or offer less favorable terms if it has already used up its quarterly limit on high-risk loans.

How to Prepare for Changes and Stay Updated

Given that Canada's mortgage regulation system is undergoing significant changes, it's important for buyers and homeowners to stay informed.

Regularly check OSFI's official website for current updates on the minimum qualifying rate and LTI rules. Keep an eye on Bank of Canada announcements about the key rate, as this affects mortgage rates and, consequently, the stress test.

Calculate your current LTI ratio by dividing your total mortgage amount (or desired mortgage) by your annual gross income. If it's approaching or exceeding 4.5, be prepared for potential complications or less favorable terms when getting an uninsured mortgage.

Work with a qualified mortgage broker who stays current with industry changes and can offer alternative solutions if one lender refuses due to LTI restrictions.

Plan ahead: if you're planning to buy or renew your mortgage in the next 12-24 months, start preparing now — improve your credit score, pay down debts, and save for a larger down payment.

In conclusion, it's worth noting that Canada's mortgage stress test remains an important factor in the real estate market as of October 2025, although the regulatory system is actively evolving. OSFI plans to complete its assessment of the LTI limits pilot program in early 2026 and may reconsider the entire mortgage regulation framework.

Possible scenarios include keeping the stress test in an updated form, completely eliminating it for uninsured mortgages, or a hybrid model combining MQR and LTI restrictions. OSFI's decision will determine whether Canada continues using the stress test or fully transitions to an LTI restriction system, following the example of other developed countries like the UK. Stay updated with OSFI announcements, consult with professionals, and prepare in advance to make the most informed decisions when buying a home or renewing your mortgage.
