A mortgage is the biggest financial commitment many Canadians will make in their lifetime. And while a mortgage is a huge responsibility, it can also mean freedom, security, and independence.

But a mortgage is a loan, and to make sure it doesn’t become an overwhelming financial burden, the government implemented measures in place to ensure current and potential homeowners don’t take on more debt than they can handle. 

Enter the mortgage stress test. If you’re looking to buy a house or are coming up on mortgage renewal time, chances are you’ve heard of it, and may have questions about what it is and whether you have to take it.

Today, we’ll tell you everything you need to know about the stress test, including how it works, how to prepare for it, and steps you can take to increase your chances of passing.

Important update for insured mortgages

As of March 16, 2020, the change of the test rate planned for April 6, 2020 that would have reduced the minimum qualifying rate and made it easier for insured mortgages to pass has been suspended indefinitely.

New rules that would have been easier to pass
The bank must use the higher interest rate of either:

  • the interest rate you negotiate with your lender
  • weekly median 5-year fixed insured mortgage rate from mortgage insurance applications, plus 2%.

The goal is to make the test more representative of the rates currently offered by lenders and more responsive to market conditions.

What is the mortgage stress test?

The test was implemented by the Office of the Superintendent of Financial Institutions Canada (OSFI) on January 1, 2018 to help ensure that all homeowners with high-ratio or uninsured mortgages are able to afford their payments in the event their financial circumstances worsen or interest rates increase. This makes mortgages are harder to qualify for, but it also provides security for homeowners.

For example, say you and your partner are a dual-income family with some residual student loans and a baby on the way. Right now, you’re both gainfully employed and making well over $100,000 a year between the two of you. At the moment, you might have no trouble getting approved for a $400,000 loan with an interest rate of 2.69%, and you’d be able to make the payments comfortably.

However, what happens in 9 months when the baby comes and one of you goes on parental leave, and possibly decides to stay home permanently with the kid. Or, what if interest rates spike, or one of you loses your job? Would you still be able to comfortably make your payments?

It is designed to ensure that if your financial circumstances change tomorrow, you’ll still be able to afford the home you bought today.

How does the stress test work?

When you apply for a mortgage, the lender or broker will lead you through the application process, and qualify you for a loan of a certain amount at a specific interest rate.

Let’s use the same numbers from the previous example and say the bank qualified you for a $400,000 loan, you negotiated down to an interest rate of 2.69%, on a 5-year fixed term, and an amortization of 25 years. Your monthly payments would be $1,829.93. 

To pass, you’d have to qualify for the same loan, but with a higher interest rate. There are two rates considered, and you have to qualify for whichever is higher in order to be approved.

Insured mortgage stress test example

Let’s assume that your down payment was less than 20%, so the mortgage will be insured. The bank must use the higher interest rate of either:

The Bank of Canada qualifying rate changes weekly. Let’s say it is 5.1%. That’s higher than 4.69%, so to pass the test, you’d have to qualify for the $400,000 loan with an interest rate of 5.1%, and monthly payments of $2,349.24.

Uninsured mortgage stress test example

Let’s assume that your down payment was greater than 20%, so the mortgage will be uninsured. The bank must use the higher interest rate of either:

To pass, you have to qualify for the $400,000 loan at an interest rate of 5.3%. With the same terms, that would mean monthly payments of $2,395.20.

What numbers are important for passing the stress test?

Passing the stress test is a numbers game, and there are a few crucial calculations lenders will look at when qualifying you. The two most important numbers are your total debt service ratio (TDS) and your gross debt service ratio (GDS).

Total debt service ratio

Your TDS is the portion of your monthly income that’s required to cover all your debts. To figure this out, start by adding together all your monthly debts, including:

  • Mortgage
  • Interest
  • Property taxes
  • Heating costs
  • Student loans
  • Car payments
  • Lines of credit
  • Personal loans
  • Other debts and financial obligations

Then, take that total and divide it by your gross annual income. To pass and get approved for a mortgage, your TDS shouldn’t be higher than 42%.

Gross debt service ratio

GDS is similar to TDS, but it looks at the portion of your income that’s needed to cover your housing costs specifically. To calculate your GDS, add up all your monthly housing costs, including mortgage, heat and utility bills, condo fees, interest, and taxes.

Divide that total by your gross annual income. To be approved, your GDS shouldn’t be higher than 35%.

Do I have to take the stress test?

It applies to all people in Canada who are applying for a mortgage or switching lenders at mortgage renewal time. This includes both high-ratio and conventional mortgages. However, only federally regulated lenders are required to administer the test, and that includes:

  • Banks
  • Trust companies
  • Monoline lenders
  • Loan companies

In other words, you’ll have to pass the test if you’re:

A) applying for your first mortgage or switching your loan to a different lender, and
B) using a conventional lender like a bank.

Can I avoid the stress test?

Yes, you can bypass it by renewing your mortgage with the same lender, rather than switching when it matures.

For new mortgages, you can avoid it by applying through an unregulated lender, which includes:

  • Credit unions
  • Private mortgage lenders
  • Mortgage finance companies

The trade off with unregulated lenders, however, is they usually charge a higher interest rate. You might be able to bypass it, but your monthly payments will be higher and your mortgage will cost more in the long run.

What can I do to make sure I pass?

When you apply for a mortgage, the two key numbers a professional will look at are your TDS and GDS. If these percentages are too high — meaning your housing expenses and total debts account for too much of your income — chances are you won’t get approved or won’t pass.

Here are some things you can do that will help you pass the test:

  • Have a larger down payment
  • Pay a lump sum on your current mortgage (for homeowners who are switching lenders)
  • Decrease your home-buying budget and look for a more affordable house
  • Cancel any loan applications that are in process
  • Pay off credit card, personal, student, car, and other loans
  • Increase your annual income
  • Find a co-signer

Conclusion

The mortgage stress test has made it more difficult for Canadians to get approved. At the same time, the rule is protecting homebuyers and homeowners from incurring too much debt, especially when housing prices continue to rise. 

Moreover, passing it will afford you peace of mind, because you’ll know you can still afford your house even if your financial situation changes.

If you’re worried, there are calculators out there you can use to give yourself a better idea of your financial standing, and steps you can take to give yourself a better chance of passing the test.

FAQ

What’s a high-ratio (insured) mortgage?

When people talk about a high-ratio mortgage, it means the buyer had less than a 20% down payment. In Canada, you can get a mortgage with a down payment as low as 5%. When the loan covers 81 to 95% of the purchase price of a house, this is a high-ratio mortgage. They must be insured through Genworth Financial, Canada Mortgage and Housing Corporation (CMHC), or Canada Guaranty.

What’s a conventional (uninsured) mortgage?

A conventional mortgage is one where the buyer had a down payment of 20% or more. These don’t require insurance.

What’s a monoline lender?

Monoline lenders are financial institutions that only provide one product or service, such as mortgages. In Canada, monoline lenders include:

  • RMG
  • Canadiana Financial
  • Street Capital
  • First National
  • Merix Financial
