What you Need to Know About the Latest Mortgage Rule Changes

Matt Chan • 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 us anytime, we’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.

When you apply for a mortgage, your employment history and status carry a lot of weight. Even if you feel secure in your job, lenders need proof that your income is reliable and will continue. To them, your employment status is one of the strongest indicators of whether you can make your mortgage payments long term. Here’s how lenders typically view different employment situations: Permanent Employment This is the gold standard. Once you’ve passed any probationary period and hold permanent status, lenders see you as a lower risk. It shows that your employer is committed to you, and your income is steady. Probationary Periods If you’re still on probation—usually 3 to 6 months, though sometimes longer—lenders may hesitate. That’s because your employer can end your contract without cause during this period. Once probation is over, you’re considered more secure. That said, context matters. If you’ve worked with the same company for years as a contractor and just transitioned into full-time employment, lenders may accept a letter from your employer confirming that probation is waived. Documentation is key here. Parental Leave Being on or about to take parental leave doesn’t mean you can’t qualify for a mortgage. As long as you have a letter from your employer guaranteeing your position and return-to-work date, lenders can use your regular salary—not your leave income—when assessing your application. Term Contracts This is one of the trickiest categories. Even highly skilled professionals with strong incomes can face challenges here. A term contract has a start and end date, which makes lenders question the stability of your future income. To use term-contract income, lenders generally want to see at least two years of history, or proof that your contract has already been renewed. The more evidence you can show of consistent employment, the stronger your case will be. The Bottom Line If you’re planning to apply for a mortgage, it’s important to understand how your employment status could affect your approval. Whether you’re starting a new job, coming back from leave, or working under contract, lenders want documentation that proves your income is reliable. 📞 If you’ve recently changed jobs or are planning a career shift, let’s connect. I can help you prepare your file so you qualify with confidence and avoid surprises in the approval process.

What Online Mortgage Calculators Can—and Can’t—Tell You Online mortgage calculators are everywhere—and on the surface, they seem like a no-brainer. You plug in some numbers, and out pops what you can “afford.” Simple, right? Not quite. While the math itself is correct, the story behind those numbers is often misleading. Mortgage qualification isn’t just about numbers—it’s about context, risk, and lender policy. And that’s where calculators fall short. The Numbers Are Accurate—but the Picture Isn’t An online calculator can show you what a payment might look like at a given interest rate, or how making extra payments could reduce your amortization. That’s useful information! But when it comes to mortgage qualification , calculators don’t account for the many variables that lenders consider, such as: Your credit history and score Employment type (salary, self-employed, contract) Outstanding debts and monthly obligations Assets, savings, and down payment source The property type and location you’re buying Lenders evaluate all these factors through their internal risk models. That means two people entering the exact same numbers into a calculator could receive very different results when they actually apply for a mortgage. Why Online Calculators Can Mislead You When you see a “How much can I afford?” or “Mortgage Qualification” calculator online, it’s easy to treat the result as fact. But these tools don’t know your financial story—they only crunch the data you enter. A calculator can’t predict how a lender views your risk, how new mortgage rules apply to your file, or how things like spousal support, car loans, or variable income will impact approval. In short: calculators estimate payments, not qualification . Use Calculators the Right Way Don’t get us wrong—online calculators still have value. Use them to explore different “what-if” scenarios: How do payments change with different down payment amounts? How would a rate increase affect affordability? What if you added $100 a month to your payments? These tools are great for helping you understand your comfort zone. Just remember: they’re a starting point, not a green light. The Real First Step: Get a Pre-Approval If you’re serious about buying a home, skip the guesswork and get a mortgage pre-approval . It’s quick, free, and gives you real-world clarity on what you can afford. A pre-approval looks at your full financial picture—income, credit, debts, assets—and provides a framework for your purchase price, payment range, and rate options. It’s the only way to get a reliable answer to the question, “What can I really afford?” Final Thoughts Online calculators are convenient, but they can’t replace expert advice. Think of them as a starting point, not a solution. A professional mortgage broker can interpret the numbers, navigate lender policies, and tailor your financing strategy to your actual situation. If you’d like help understanding your true buying power—or want to get pre-approved with confidence— reach out anytime . I’d be happy to walk you through your options and help you make sense of the numbers.

Going Through a Divorce? Don’t Let Your Credit Take the Hit Divorce is stressful enough without adding financial fallout to the mix. Between lawyers, paperwork, and emotional strain, it’s easy to overlook how a separation can impact your credit. But your financial future depends on protecting it now—because long after the dust settles, a damaged credit score can linger. Here are a few smart steps to help keep your credit strong and your finances steady as you move forward. 1. Take Control of Joint Debts When it comes to joint debt, both parties are equally responsible—no matter what your divorce agreement says. If your ex misses a payment on an account with your name attached, your credit takes the hit too. Go through all joint credit cards, loans, and lines of credit. Wherever possible: Close joint accounts to stop future shared use. Transfer balances to the person responsible for repayment. Notify lenders in writing of any changes to account ownership. Once everything is updated, pull your credit report after three to six months to confirm all joint accounts have been closed and reporting correctly. Mistakes happen—stay proactive to prevent surprises later. 2. Open Your Own Bank Accounts Separation means financial independence, and that starts with your own banking. Open a new chequing account in your name only and redirect your pay deposits and bill payments there. At the same time, close any joint bank accounts and change passwords on existing online banking and credit profiles. Even in peaceful separations, shared access can cause confusion—or conflict. Protect yourself by ensuring your money and information are secure. 3. Start Building Credit in Your Name If most of your past credit was tied to your spouse’s name, now’s the time to establish your own. Apply for a small personal credit card or secured credit product . Use it sparingly and pay it off in full each month. This helps you build a solid individual credit history, setting the stage for future goals like buying a home, refinancing, or starting fresh financially. 4. Keep an Eye on Your Credit Monitor your credit report regularly for errors or unexpected changes. You can request free reports from both major credit bureaus in Canada— Equifax and TransUnion —once a year. Tracking your credit isn’t just about catching mistakes; it helps you see your progress as you rebuild your financial independence. Final Thoughts Divorce can be emotionally draining, but protecting your credit doesn’t have to be complicated. By taking a few careful steps now—closing joint accounts, building credit in your name, and monitoring your reports—you’ll safeguard your financial health and gain peace of mind as you start your next chapter.
