What you Need to Know About the Latest Mortgage Rule Changes

Sabeena Bubber • 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

How Property Type and Condition Influence Mortgage Financing

By Sabeena Bubber • October 21, 2026
Why the Property Matters When You’re Qualifying for a Mortgage When qualifying for a mortgage, lenders typically look at four core areas: Income Credit Down payment or equity The property itself Most buyers focus heavily on income, credit, and savings—and for good reason. But even if those boxes are checked, the property can still determine whether a mortgage is approved. Why Lenders Care About the Property From a lender’s perspective, the property is the collateral for the mortgage. In the unlikely event of default, they need to know the home can be sold quickly and at fair market value to recover their funds. Because of this, lenders are careful about the condition, value, and marketability of any property they finance. Homes that are in poor repair, unconventional, or overpriced can raise red flags—even when the borrower is well qualified. Appraisals Are Always Part of the Process Every mortgage requires an appraisal to confirm value. Insured mortgages (through CMHC, Sagen, or Canada Guaranty) often use an automated valuation model completed online. Conventional mortgages typically require a full, on-site appraisal by a certified appraiser. This appraisal is not optional and happens after an offer is accepted—not at the pre-approval stage. Why Pre-Approvals Aren’t a Guarantee A pre-approval is a great first step, but it only assesses you, not the property. Once you’ve made an offer, the lender must approve the specific home you’re buying. Understanding this upfront helps avoid surprises and confusion later in the process. The Risk of Buying Without a Financing Condition In competitive markets, buyers sometimes remove financing conditions to strengthen their offer. However, this comes with risk. If the appraisal comes back low—or the lender is concerned about the property’s condition—you could be denied financing after the offer is firm. In that scenario, your deposit may be at risk. Buying a Home That Needs Work If you’re considering a property that isn’t in perfect condition, there are solutions. A purchase plus improvements program allows you to buy a home and include renovation costs in your mortgage. The process is structured and requires planning, but it can be an excellent way to turn a fixer-upper into a great long-term investment. Final Thoughts Mortgage approval isn’t based solely on your finances—the property matters just as much. Knowing this ahead of time helps you make smarter offers, reduce risk, and plan more effectively. If you’re buying a property that needs work or want clarity on how a lender may view a specific home, feel free to reach out. I’d be happy to walk you through your options and help you plan with confidence.

How to Maximize Your Mortgage Renewal Opportunity

By Sabeena Bubber • October 14, 2026
Your Lender Is Not Obligated to Renew Your Mortgage Many homeowners assume that if they’ve made every mortgage payment on time, their lender is automatically required to renew their mortgage at the end of the term. That’s a common belief—but it isn’t true. When you sign a mortgage, you’re agreeing to a contract for a specific term . Once that term ends, the lender has the legal right to either renew the mortgage or call the loan . There is no obligation to offer a renewal. In practice, most lenders do renew mortgages—but certain situations can prevent that from happening. Reasons a Lender May Decline to Renew A lender may choose not to renew if: Mortgage payments were missed during the term A bankruptcy or consumer proposal has occurred There is a separation or divorce Employment or income has changed A borrower on the mortgage has passed away The lender no longer prefers the property’s location or market The lender is no longer licensed to lend in Canada Even one of these factors can change how a lender views the risk. Why This Matters Because renewal is not guaranteed, waiting until the last minute can put you in a difficult position. Understanding this reality early gives you time and control. How to Protect Yourself at Renewal The best approach is to be proactive. Ideally, you should begin reviewing your options 120 days before your mortgage term ends . This gives you enough time to explore alternatives and make informed decisions—rather than reacting under pressure. Even if your current lender offers a renewal, that’s just one option , not automatically the best one. The lender that was right for you years ago may no longer offer the most competitive rate, terms, or flexibility today. The goal at renewal isn’t convenience—it’s reducing your total cost of borrowing and choosing terms that align with your current situation. Why Work With an Independent Mortgage Professional Working with an independent mortgage professional ensures someone is advocating for you , not the lender. Instead of being limited to one set of products, you can compare options across multiple lenders and choose the solution that best protects your interests. Final Thoughts Whether your lender is offering a renewal or not, the smartest move is to review all your options before signing anything. If your mortgage is coming up for renewal—or if you want to plan ahead—feel free to connect anytime. I’d be happy to help you protect your options and make a confident decision.
