What Is the Mortgage Stress Test in Canada and How Does It Work?

If you're planning to buy a home in Canada, you've probably heard about the mortgage stress test. But what exactly is it, and why does it matter to you as a potential homebuyer? Let’s break it down in simple terms.

Understanding the Mortgage Stress Test in Canada

The mortgage stress test is a set of rules implemented by the Canadian government to ensure that borrowers can afford their mortgage payments even if interest rates rise. This measure is based on guidelines set by the Office of the Superintendent of Financial Institutions (OSFI). You can review the detailed B-20 guideline on their official website. In essence, it’s a financial safeguard designed to prevent homeowners from taking on more debt than they can handle.

Introduced in 2018, the stress test applies to all new mortgage applications and mortgage renewals with a different lender. These rules are outlined in OSFI’s B-20 guideline for residential mortgage underwriting practices. It’s overseen by the Office of the Superintendent of Financial Institutions (OSFI) for federally regulated lenders.

Why Is the Mortgage Stress Test Important?

Canada’s real estate market is one of the most expensive in the world, especially in cities like Toronto and Vancouver, according to a 2023 report by the Canadian Real Estate Association (CREA). The stress test helps mitigate the risk of financial instability caused by rising interest rates or unexpected economic changes. A case study by OSFI in 2022 highlighted how these measures reduced the number of high-risk mortgages during economic downturns. By ensuring borrowers have a financial buffer, the stress test aims to protect both individual homeowners and the broader economy.

How Does the Mortgage Stress Test Work?

When you apply for a mortgage, lenders don’t just evaluate your ability to make payments based on the current interest rate. Instead, they assess your finances using a higher qualifying interest rate to simulate potential future increases. Here’s how it’s calculated:

1. Qualifying Rate: Lenders use the higher of:

   • The Bank of Canada’s benchmark rate (currently 5.25%).

   • Your contracted mortgage rate plus 2%.

     
     

2. Affordability Assessment: Lenders calculate your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios, which include housing costs and overall debt obligations. These ratios must fall within allowable limits when tested at the qualifying rate.

   
   

Who Does the Stress Test Apply To?

The mortgage stress test applies to:

• First-Time Homebuyers: Even with government incentives, first-time buyers must pass the stress test.

  
  

• Mortgage Renewals: If you’re switching lenders at renewal, you’ll need to pass the stress test.

  
  

• Refinancing: Any refinanced mortgage is subject to the stress test.

How to Prepare for the Mortgage Stress Test?

To improve your chances of passing the stress test, consider these tips:

1. Boost Your Credit Score: A higher credit score may help you qualify for better rates and improve your overall application.

   
   

2. Save for a Larger Down Payment: The more you put down, the less you’ll need to borrow, making it easier to meet the stress test criteria.

   
   

3. Pay Down Existing Debt: Lowering your debt obligations improves your TDS ratio, which lenders consider during the stress test.

   
   

4. Understand Your Budget: Use online mortgage calculators from CMHC to estimate how much you can afford under stress test conditions

What Happens If You Don’t Pass the Stress Test?

Failing the mortgage stress test doesn’t mean the end of your homeownership dreams. Here’s what you can do:

• Adjust Your Budget: Consider looking at homes in a lower price range.

  
  

• Seek a Co-Signer: Adding a financially stable co-signer could improve your application.

  
  

• Explore Alternative Lenders: Some non-federally regulated lenders may offer options that don’t require the stress test. You can explore such options through the Canadian Credit Union Association (CCUA).
