What you Need to Know About the Latest Mortgage Rule Changes

Marci • 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.

Mortgage Approval 101: GDS & TDS Explained

By Marci Deane • March 4, 2026
Can You Afford That Mortgage? Let’s Talk About Debt Service Ratios One of the biggest factors lenders look at when deciding whether you qualify for a mortgage is something called your debt service ratios. It’s a financial check-up to make sure you can handle the payments—not just for your new home, but for everything else you owe as well. If you’d rather skip the math and have someone walk through this with you, that’s what I’m here for. But if you like to understand how things work behind the scenes, keep reading. We’re going to break down what these ratios are, how to calculate them, and why they matter when it comes to getting approved. What Are Debt Service Ratios? Debt service ratios measure your ability to manage your financial obligations based on your income. There are two key ratios lenders care about: Gross Debt Service (GDS) This looks at the percentage of your income that would go toward housing expenses only. Total Debt Service (TDS) This includes your housing costs plus all other debt payments—car loans, credit cards, student loans, support payments, etc. How to Calculate GDS and TDS Let’s break down the formulas. GDS Formula: (P + I + T + H + Condo Fees*) ÷ Gross Monthly Income Where: P = Principal I = Interest T = Property Taxes H = Heat Condo fees are usually calculated at 50% of the total amount TDS Formula: (GDS + Monthly Debt Payments) ÷ Gross Monthly Income These ratios tell lenders if your budget is already stretched too thin—or if you’ve got room to safely take on a mortgage. How High Is Too High? Most lenders follow maximum thresholds, especially for insured (high-ratio) mortgages. As of now, those limits are typically: GDS: Max 39% TDS: Max 44% Go above those numbers and your application could be declined, regardless of how confident you feel about your ability to manage the payments. Real-World Example Let’s say you’re earning $90,000 a year, or $7,500 a month. You find a home you love, and the monthly housing costs (mortgage payment, property tax, heat) total $1,700/month. GDS = $1,700 ÷ $7,500 = 22.7% You’re well under the 39% cap—so far, so good. Now factor in your other monthly obligations: Car loan: $300 Child support: $500 Credit card/line of credit payments: $700 Total other debt = $1,500/month Now add that to the $1,700 in housing costs: TDS = $3,200 ÷ $7,500 = 42.7% Uh oh. Even though your GDS looks great, your TDS is just over the 42% limit. That could put your mortgage approval at risk—even if you’re paying similar or higher rent now. What Can You Do? In cases like this, small adjustments can make a big difference: Consolidate or restructure your debts to lower monthly payments Reallocate part of your down payment to reduce high-interest debt Add a co-applicant to increase qualifying income Wait and build savings or credit strength before applying This is where working with an experienced mortgage professional pays off. We can look at your entire financial picture and help you make strategic moves to qualify confidently. Don’t Leave It to Chance Everyone’s situation is different, and debt service ratios aren’t something you want to guess at. The earlier you start the conversation, the more time you’ll have to improve your numbers and boost your chances of approval. If you're wondering how much home you can afford—or want help analyzing your own GDS and TDS—let’s connect. I’d be happy to walk through your numbers and help you build a solid mortgage strategy.

Start Smart: Get Pre-Approved for Your Mortgage

By Marci Deane • February 25, 2026
Thinking of Buying a Home? Here’s Why Getting Pre-Approved Is Key If you’re ready to buy a home but aren’t sure where to begin, the answer is simple: start with a pre-approval. It’s one of the most important first steps in your home-buying journey—and here's why. Why a Pre-Approval is Crucial Imagine walking into a restaurant, hungry and excited to order, but unsure if your credit card will cover the bill. It’s the same situation with buying a home. You can browse listings online all day, but until you know how much you can afford, you’re just window shopping. Getting pre-approved for a mortgage is like finding out the price range you can comfortably shop within before you start looking at homes with a real estate agent. It sets you up for success and saves you from wasting time on properties that might be out of reach. What Exactly is a Pre-Approval? A pre-approval isn’t a guarantee. It’s not a promise that a lender will give you a mortgage no matter what happens with your finances. It’s more like a preview of your financial health, giving you a clear idea of how much you can borrow, based on the information you provide at the time. Think of it as a roadmap. After going through the pre-approval process, you’ll have a much clearer picture of what you can afford and what you need to do to make the final approval process smoother. What Happens During the Pre-Approval Process? When you apply for a pre-approval, lenders will look at a few key areas: Your income Your credit history Your assets and liabilities The property you’re interested in This comprehensive review will uncover any potential hurdles that could prevent you from securing financing later on. The earlier you identify these challenges, the better. Potential Issues a Pre-Approval Can Reveal Even if you feel confident that your finances are in good shape, a pre-approval might uncover issues you didn’t expect: Recent job changes or probation periods An income that’s heavily commission-based or reliant on extra shifts Errors or collections on your credit report Lack of a well-established credit history Insufficient funds saved for a down payment Existing debt reducing your qualification amount Any other financial blind spots you might not be aware of By addressing these issues early, you give yourself the best chance of securing the mortgage you need. A pre-approval makes sure there are no surprises along the way. Pre-Approval vs. Pre-Qualification: What’s the Difference? It’s important to understand that a pre-approval is more than just a quick online estimate. Unlike pre-qualification—which can sometimes be based on limited information and calculations—a pre-approval involves a thorough review of your finances. This includes looking at your credit report, providing detailed documents, and having a conversation with a mortgage professional about your options. Why Get Pre-Approved Now? The best time to secure a pre-approval is as soon as possible. The process is free and carries no risk—it just gives you a clear path forward. It’s never too early to start, and by doing so, you’ll be in a much stronger position when you're ready to make an offer on your dream home. Let’s Make Your Home Buying Journey Smooth A well-planned mortgage process can make all the difference in securing your home. If you’re ready to get pre-approved or just want to chat about your options, I’d love to help. Let’s make your home-buying experience a smooth and successful one!

Your Guide to Real Estate Investment in Canada

By Marci Deane • February 18, 2026
Your Guide to Real Estate Investment in Canada Real estate has long been one of the most popular ways Canadians build wealth. Whether you’re purchasing your first rental property or expanding an existing portfolio, understanding how real estate investment works in Canada—and how it’s financed—is key to making smart decisions. This guide walks through the fundamentals you need to know before getting started. Why Canadians Invest in Real Estate Real estate offers several potential benefits as an investment: Long-term appreciation of property value Rental income that can support cash flow Leverage , allowing you to invest using borrowed funds Tangible asset with intrinsic value Portfolio diversification beyond stocks and bonds When structured properly, real estate can support both income and long-term net worth growth. Types of Real Estate Investments Investors typically focus on one or more of the following: Long-term residential rentals Short-term or vacation rentals (subject to local regulations) Multi-unit residential properties Pre-construction or assignment purchases Value-add properties that require renovations Each type comes with different financing rules, risks, and return profiles. Down Payment Requirements for Investment Properties In Canada, investment properties generally require higher down payments than owner-occupied homes. Typical minimums include: 20% down payment for most rental properties Higher down payments may be required depending on: Number of units Property type Borrower profile Lender guidelines Down payment source, income stability, and credit history all play a role in approval. How Rental Income Is Used to Qualify Lenders don’t always count 100% of rental income. Depending on the lender and mortgage product, they may: Use a rental income offset , or Include a percentage of rental income toward qualification Understanding how income is treated can significantly impact borrowing power. Financing Options for Investors Investment financing can include: Conventional mortgages Insured or insurable options (in limited scenarios) Alternative or broker-only lenders Refinancing equity from existing properties Purchase plus improvements for value-add projects Access to multiple lenders is often crucial for investors as portfolios grow. Key Costs Investors Should Plan For Beyond the purchase price, investors should budget for: Property taxes Insurance Maintenance and repairs Vacancy periods Property management fees (if applicable) Legal and closing costs A realistic cash-flow analysis is essential before buying. Risk Considerations Like any investment, real estate carries risk. Key factors to consider include: Interest rate changes Market fluctuations Tenant turnover Regulatory changes Liquidity (real estate is not easily sold quickly) A strong financing structure can help manage many of these risks. The Role of a Mortgage Professional Investment mortgages are rarely “one-size-fits-all.” Lender policies vary widely, especially as you acquire more properties. Working with an independent mortgage professional allows you to: Compare multiple lender strategies Structure financing for long-term growth Preserve flexibility as your portfolio evolves Avoid costly mistakes early on Final Thoughts Real estate investment in Canada can be a powerful wealth-building tool when approached with a clear strategy and proper financing. Whether you’re exploring your first rental property or planning your next acquisition, understanding the numbers—and the lending landscape—matters.
