More Changes to Mortgage Qualification on the Horizon?

Katherine Martin • August 8, 2016

Given the current economic environment in Canada, with record levels of household indebtedness and growing risks and vulnerabilities in some housing markets, OSFI’s supervisory scrutiny in the area of mortgage underwriting will continue.” This was included in Reinforcing Prudent Residential Mortgage Risk Management published early July by the Office of the Superintendent of Financial Institutions (OSFI).

The purpose of this nice and tidy piece of government correspondence is to inform the public that OSFI will be upping their game, paying closer attention to mortgage underwriting policies. And although no hard and fast rule changes were announced, an announcement of “hey, we are paying really close attention here” is typically not made unless there has been at least some thought about what the next steps might be (if required).

So let’s take a look at some of the potential changes the government could make to mortgage qualification.

Qualifying All Terms at the Benchmark Rate

As it stands right now, variable rate mortgages and fixed rate mortgages with terms of less than five years are qualified using the benchmark rate. The benchmark rate is set higher than the actual contract rate and is used to “stress test” mortgage applications.

In our current low interest rate environment, many Canadians see the five year fixed mortgage as a good choice simply because it qualifies using the contract rate instead of the benchmark rate. This means using the five year rate, borrowers can qualify for a lot more house compared to a shorter fixed term or variable rate mortgage.

Forcing all mortgages to be qualified at the benchmark rate could be on the horizon and would most likely lessen the appeal of the five year fixed rate.

Increasing the Benchmark Rate

If the goal is to tighten mortgage qualification, a simple way to do that would be to increase the benchmark slowly but surely. The higher the qualifying rate, the less you qualify for. Plain and simple. However as this might have other economic ramifications, we’ll just have to wait and see if this is in the government playbook.

Lower Debt Service Ratios

In order to qualify for a mortgage, you take your principal, interest, taxes, and heat and divide by your annual income, this is called your gross debt service ratio or GDS. When you add your other debt obligations to this calculation, it becomes your total debt service ratio or TDS.

Currently, for insured mortgages in Canada, your maximum GDS is limited to 39% while your TDS is capped at 42%.

A simple tweak to these numbers would have a pretty significant impact.

A Flat 10% Down Payment

If you remember, back in February of 2016, the government increased the minimum down payment amount. When purchasing a property, the first $500,000 requires a minimum of 5% down, whereas the portion of the purchase price above $500,000 now requires a 10% down payment.

Seeing as though the government just made these changes, it doesn’t seem likely that they would scrap them and simply introduce a flat 10% downpayment across the board, but you never know!

Regardless of what future changes are made to mortgage qualifications (if any) to address “our current economic environment”, you can count on us to make sure you are kept in the know.

What Online Mortgage Calculators Can—and Can’t—Tell You

By Katherine Martin • July 8, 2026
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.

Everything You Need to Know About Mortgage Financing in Canada

By Katherine Martin • July 1, 2026
For most Canadians, buying a home isn’t possible without a mortgage. And while getting a mortgage may seem straightforward—borrow money, buy a home, pay it back—it’s the details that make the difference. Understanding how mortgages work (and what to watch out for) is key to keeping your borrowing costs as low as possible. The Basics: How a Mortgage Works A mortgage is a loan secured against your property. You agree to pay it back over an amortization period (often 25 years), divided into shorter terms (ranging from 6 months to 10 years). Each term comes with its own interest rate and rules. While the interest rate is important, it’s not the only thing that determines the true cost of your mortgage. Features, penalties, and flexibility all play a role—and sometimes a slightly higher rate can save you thousands in the long run. Key Questions to Ask Before Choosing a Mortgage How long will you stay in the property? Your timeframe helps determine the right term length and product. Do you need flexibility to move? If a work transfer or lifestyle change is possible, portability may be important. What are the penalties for breaking the mortgage early? This is one of the biggest factors in the real cost of borrowing. A low rate won’t save you if breaking costs you tens of thousands. How are penalties calculated? Some lenders use more borrower-friendly formulas than others. It’s not easy to calculate yourself—get professional help. Can you make extra payments? Prepayment privileges allow you to pay off your mortgage faster, potentially saving years of interest. How is the mortgage registered on title? Some registrations (like collateral charges) can limit your ability to switch lenders at renewal without extra costs. Which type of mortgage fits best? Fixed, variable, HELOCs, or even reverse mortgages each have their place depending on your financial and life situation. What’s your down payment? A larger down payment could reduce or eliminate mortgage insurance premiums, saving thousands upfront. Why the Lowest Rate Isn’t Always the Best Choice It’s tempting to chase the lowest rate, but mortgages with rock-bottom pricing often come with restrictive terms. For example, saving 0.10% on your rate may put a few extra dollars in your pocket each month, but if the mortgage has harsh penalties, you could end up paying thousands more if you break it early. The goal isn’t just the lowest rate—it’s the lowest overall cost of borrowing . That’s why it’s so important to look beyond the headline number and consider the whole picture. The Bottom Line Mortgage financing in Canada is about more than rate shopping. It’s about aligning your mortgage with your financial goals, lifestyle, and future plans. The best way to do that is to work with an independent mortgage professional who can walk you through the fine print and help you secure the product that truly keeps your costs low. If you’d like to explore your options—or review your current mortgage to see if it’s really working in your favour—let’s connect. I’d be happy to help.
