What you Need to Know About the Latest Mortgage Rule Changes

Katherine Martin • October 17, 2017

If you’ve tuned into the news today, you’ve probably heard that there are new mortgage rules coming into effect on January 1st. 2018. Over the next week you’ll most likely hear a lot of commentary on whether these rules are good, bad, necessary, or unnecessary. And no doubt someone somewhere will come to the conclusion that no one will ever get a mortgage again, and that the housing market in Canada is going to come crashing down around us. Please remember that it’s the media’s job to write headlines and attract eyes, so they tend to sensationalize everything. Take what you hear with a grain of salt. Mortgages will still be written, and houses will still be bought.  

At the end of the day, these new rules (outlined below) will come into play, and there’s nothing we can do to change the government’s mind. So how do we respond? Well… as it becomes increasingly difficult to qualify for a mortgage, your goal should be to work with a mortgage professional that gives you more choices. Instead of working with a single institution; having access to a single line of mortgage products, when you work with a mortgage broker, you have access to many different lenders, with a wide variety of choices.

As mortgage rules tighten, your goal should be to find as much flexibility as possible, you do this by working with a mortgage broker. So if you have any questions about your mortgage, please don’t hesitate to contact me anytime , I’d love to have a conversation with you. 

Okay, so on to the changes… the biggest change to the rules surrounding mortgage qualification is that a requirement to stress test each mortgage will be now applied to all borrowers, instead of just borrowers who have less than a 20% downpayment. Qualification for all mortgages will now be made at a minimum qualifying rate which is the greater of  the five-year benchmark rate published by the Bank of Canada or the contractual mortgage rate +2%. 

OSFI (The Office of the Superintendent of Financial Institutions) released their final version of their new guidelines for the mortgage industry. Below is the news release from OSFI. called: OSFI is reinforcing a strong and prudent regulatory regime for residential mortgage underwriting

News Release

For Immediate Release

OTTAWA – October 17, 2017 – Office of the Superintendent of Financial Institutions Canada

Today the Office of the Superintendent of Financial Institutions Canada (OSFI) published the final version of Guideline B-20 −  Residential Mortgage Underwriting Practices and Procedures. The revised Guideline, which comes into effect on January 1, 2018, applies to all federally regulated financial institutions.

The changes to Guideline B-20 reinforce OSFI’s expectation that federally regulated mortgage lenders remain vigilant in their mortgage underwriting practices. The final Guideline focuses on the minimum qualifying rate for uninsured mortgages, expectations around loan-to-value (LTV) frameworks and limits, and restrictions to transactions designed to circumvent those LTV limits.

OSFI is setting a new minimum qualifying rate, or “stress test,” for uninsured mortgages.

  • Guideline B-20 now requires the minimum qualifying rate for uninsured mortgages to be the greater of  the five-year benchmark rate published by the Bank of Canada or the contractual mortgage rate +2%.

OSFI is requiring lenders to enhance their loan-to-value (LTV) measurement and limits so they will be dynamic and responsive to risk.

  • Under the final Guideline, federally regulated financial institutions must establish and adhere to appropriate LTV ratio limits that are reflective of risk and are updated as housing markets and the economic environment evolve.

OSFI is placing restrictions on certain lending arrangements that are designed, or appear designed to circumvent LTV limits.

  • A federally regulated financial institution is prohibited from arranging with another lender a mortgage, or a combination of a mortgage and other lending products, in any form that circumvents the institution’s maximum LTV ratio or other limits in its residential mortgage underwriting policy, or any requirements established by law.

“These revisions to Guideline B-20 reinforce a strong and prudent regulatory regime for residential mortgage underwriting in Canada,” said Superintendent Jeremy Rudin.

Quick Facts

  • On July 7, 2017, OSFI published draft revisions to Guideline B-20 –  Residential Mortgage Underwriting Practices and Procedures. The consultation period ended on August 17, 2017.
  • OSFI received more than 200 submissions from federally regulated financial institutions, financial industry associations, other organizations active in the mortgage market, as well as the general public.
  • The cover letter includes an unattributed summary of the comments and an explanation of how these issues were dealt with in the final Guideline B-20.
  • Following publication of Guideline B-20 OSFI plans to assess Guideline B-21 −  Residential Mortgage Insurance Underwriting Practices and Procedures  for consequential amendments.

Alternative Lending in Canada: What It Is and When It Makes Sense Not everyone fits into the traditional lending box—and that’s where alternative mortgage lenders come in. Alternative lending refers to any mortgage solution that falls outside of the typical big bank offerings. These lenders are flexible, creative, and focused on helping Canadians who may not qualify for traditional financing still access the real estate market. Let’s explore when alternative lending might be the right fit for you. 1. You Have Damaged Credit Bad credit doesn’t have to mean your homeownership dreams are over. Many alternative lenders take a big-picture approach . While credit scores matter, they’ll also look at: Stable employment Consistent income Size of your down payment or existing equity If your credit has taken a hit but you can demonstrate strong income and savings—or have a solid explanation for past credit issues— an alternative lender may approve your mortgage when a bank won’t. Pro tip: Use an alternative mortgage as a short-term solution while you rebuild your credit, then refinance into a traditional mortgage with better terms down the line. 2. You're Self-Employed Being your own boss has its perks—but mortgage approval isn’t usually one of them. Traditional lenders require verifiable, consistent income—often two years’ worth. But self-employed Canadians typically write off significant expenses, reducing their declared income. Alternative lenders are more flexible and understanding of self-employed income structures. If your business is profitable and your personal finances are healthy, you may qualify even with lower stated income. Even if interest rates are slightly higher, this option is often worth it—especially when balanced against tax planning and business deductions . 3. You Earn Non-Traditional Income Today’s income sources aren’t always conventional. If you earn through: Airbnb rentals Tips and gratuities Rideshare or delivery apps (like Uber or Uber Eats) Commissions or contracts You might face challenges with traditional lenders. Alternative lenders are often more willing to work with these non-standard income streams , especially if the rest of your mortgage application is strong. Some will consider a shorter income history or evaluate your average earnings in a more flexible way. 4. You Need Expanded Debt-Service Ratios Canada’s mortgage stress test has made it harder for many borrowers to qualify with big banks. Alternative lenders can offer more generous debt-service ratio limits —meaning you might be able to qualify for a larger mortgage or a more suitable home, especially in competitive markets. While traditional GDS/TDS limits typically sit at 35/42 or 39/44 (depending on your credit), some alternative lenders will go higher, especially if: You have a larger down payment Your loan-to-value ratio is lower Your overall financial profile is strong It’s not a free-for-all—but it’s more flexible than bank lending. So, Is Alternative Lending Right for You? Alternative lending is designed to offer solutions when life doesn’t fit the traditional mold . Whether you're rebuilding credit, running your own business, or earning income in new ways, this path could help you get into a home sooner—or keep your current one. And here’s the key: You can only access alternative lenders through the mortgage broker channel . Let’s Explore Your Options Not sure where you fit? That’s okay. Every mortgage story is unique—and I’m here to help you write yours. If you’re curious about alternative mortgage products, want a second opinion, or need help getting approved, let’s talk . I’d be happy to help you explore the best solution for your situation. Reach out anytime. It would be a pleasure to work with you.
