What you Need to Know About the Latest Mortgage Rule Changes

Anita Groves • 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, 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.

  • 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.

You’d think an online calculator is a pretty straightforward device, one that you should be able to place your confidence in, and for the most part, they are. Calculators calculate numbers. The numbers are reliable, but how you interpret those numbers, not so much, especially if the goal is mortgage qualification. If you rely on the numbers from a “What can I afford” or “Mortgage Qualification” calculator without talking to an independent mortgage professional, you’re going to be misinformed. Don’t be fooled. Even though an online mortgage calculator can help you calculate mortgage payments or help you assess how additional payments would impact your amortization, they’ll never be able to give you an exact picture of what you can afford and how a lender will consider your mortgage application. While mortgage calculators are objective, mortgage lending isn’t. It’s 100% subjective. Lenders consider your financial situation, employment, credit history, assets, liabilities, the property you are looking to purchase. Then, they will compare that with whatever internal risk profile they are currently using to assess mortgage lending. Simply put, they don’t just look at the numbers. An online calculator is a great tool to help you run different financial scenarios and help assess your comfort level with different payment schedules and mortgage amounts. However, if you rely on an online calculator for mortgage qualification purposes, you’ll be disappointed. The first step in the mortgage qualification process is a preapproval. A preapproval will examine all the variables on your application, assess your financial situation, and provide you with a framework to buy a property based on your unique circumstance. Securing a preapproval comes at no cost to you and without any obligation to buy. It’ll simply allow you the freedom to move ahead with confidence, knowing exactly where you stand. Something a calculator is unable to do. Please connect anytime if you’d like to talk more about your financial situation and get a preapproval started. It would be a pleasure to work with you.

If you’re a first-time homebuyer eyeing a new build or major renovation, there's encouraging news that could make homeownership significantly more affordable. The federal government has proposed a new GST rebate aimed at easing the financial burden for Canadians entering the housing market. While still awaiting parliamentary approval, the proposed legislation offers the potential for thousands in savings —and could be a game-changer for buyers trying to break into today’s high-cost housing landscape. What’s Being Proposed? Under the new legislation, eligible first-time homebuyers would receive: A full GST rebate on homes priced up to $1 million A partial GST rebate on homes between $1 million and $1.5 million This could mean up to $50,000 in tax savings on a qualifying home—a major boost for anyone working hard to save for a down payment or meet mortgage qualification requirements. Why This Matters With interest rates still elevated and home prices holding steady in many regions, affordability remains a challenge. This rebate could offer meaningful relief in several ways: Lower Upfront Costs: Removing GST from the purchase price reduces the total amount of money buyers need to save before closing. Smaller Monthly Payments: A lower purchase price leads to a smaller mortgage, which translates to more manageable monthly payments. Improved Mortgage Qualification: With a reduced purchase amount, buyers may find it easier to meet lender criteria. According to recent estimates, a homebuyer purchasing a $1 million new home could see monthly mortgage payments drop by around $240 —money that could go toward savings, home improvements, or simply everyday expenses. Helping Families Help Each Other This proposal also offers a win for parents who are supporting their children in buying a first home. Whether through gifted down payments or co-signing, a lower purchase price and more affordable monthly costs mean that family support can go further—and set first-time buyers up for long-term success. Is This the Right Time to Buy? If you’re thinking about buying a new or substantially renovated home, this proposed rebate could dramatically improve your financial position. Now is the perfect time to explore your options and make sure your mortgage strategy is aligned with potential policy changes. 📞 Let’s connect for a free mortgage review or pre-approval. Whether you’re buying your first home or helping someone else take that first step, I’m here to help you make informed, confident decisions.
