Further Tightening of the Mortgage Belt

Katherine Martin • September 19, 2016

Before reading this you should be warned that the following content is pretty dry… like eating 8 saltine crackers without drinking water dry. If you need to go and get something to drink before proceeding, no worries, we will wait here. Take your time. 

The quick and dirty version, as of November 1st 2016, OSFI is going to require banks to have more money on hand to protect them in case the Canadian economy decides to ride a shark with 200 pounds of dynamite strapped to it’s chest into the mouth of an active volcano. This means two things, banks will probably slowly increase rates to cover their costs and secondly you will probably see mortgage qualification tighten a little further. 

Here is all you need to know on the subject, sourced from a few different places online. 

OSFI

On September 9th, The Office of the Superintendent of Financial Institutions (OSFI) released for public consultation, revisions to its Capital Adequacy Requirements Guideline (CAR). The following is the official release:

OSFI’s CAR Guideline provides a framework for assessing the capital adequacy of federally regulated deposit-taking institutions and is updated periodically to ensure that capital requirements continue to reflect underlying risks and developments in the financial industry.

The CAR Guideline is based on requirements agreed by the Basel Committee on Banking Supervision. As a member of the Basel Committee, OSFI supports and applies the global risk-based framework to its regulated institutions through a measured and tailored approach that is suited to the Canadian context.

Captured in this set of revisions are OSFI’s expectations on the domestic implementation of two global capital adequacy standards issued by the Basel Committee in recent years. In this draft, OSFI outlines its discretionary approach to the implementation of the Basel III countercyclical buffer regime in Canada as well as provides guidance on the application of Basel’s equity investment in funds rules, which require institutions to hold adequate capital against equity investments in funds.

To reflect the changing risks in the Canadian mortgage market, the draft CAR Guideline has also been updated to include planned revisions to the treatment of insured residential mortgages (see OSFI’s December 2015 letter to industry ). Through the capital framework, OSFI is clarifying the conditions under which risk mitigation benefits of mortgage insurance are recognized for regulatory capital purposes. These changes aim to reinforce the need for banks to exercise prudent underwriting and proper due diligence when originating insured mortgages.

Finally, the revisions to the draft guideline provide clarification on how OSFI’s capital framework will apply to federal credit unions.

Quick Facts

  • The implementation date for these changes is set for November 1, 2016 for institutions with an October 31 year end, and January 1, 2017 for institutions with a December 31 year end.
  • OSFI is inviting comments on the proposed updates, which it will consider during the development of the final version of the guideline. The deadline for submitting comments is October 18, 2016.
  • A non-attributed summary of industry comments received along with OSFI’s responses will be posted on OSFI’s website when the final version of the guideline is released.

About OSFI

The Office of the Superintendent of Financial Institutions (OSFI) is an independent agency of the Government of Canada, established in 1987, to protect depositors, policyholders, financial institution creditors and pension plan members, while allowing financial institutions to compete and take reasonable risks.

Canadian Mortgage Trends

As most people don’t care to read straight government correspondence, Canadian Mortgage Trends, a publication of Mortgage Professionals Canada published an article summarizing the Capital Adequacy Requirements.

“Under the proposed revised guideline, the amount of capital required to be held by the institutions is not expected to change significantly,” assured a spokesperson. “These changes aim to ensure that capital requirements continue to reflect underlying risks and developments in the financial industry.”

The article goes on to describe an interesting change called a “countercyclical buffer”… if that doesn’t spin you around on your chair, nothing will! Hot stuff! Anyway…

Money Sense Magazine

Not one to miss a chance at a sensational headline, Money Sense Magazine published an article called “Expect tougher mortgage rules by November”. The article goes on to outline the following:

  • Hot markets prompt tougher rules for banks
  • Taxpayer will be less exposed
  • How it will impact the Canadian home buyer
  • When will tougher rules take affect?

Start Smart: Get Pre-Approved for Your Mortgage

By Katherine Martin • November 19, 2025
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!

Mortgage Approval 101: GDS & TDS Explained

By Katherine Martin • November 12, 2025
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. 2. 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.
