Genworth Canada is the largest private residential mortgage insurance company in Canada. They have an excellent education website over at homeownership.ca. Recently, Genworth published an article discussing the recent changes to mortgage rules and how they impact affordability, here it is for your reading pleasure.

Canada’s new mortgage rules: Will they affect affordability?

In late 2016, Canada’s new mortgage rules – aimed at promoting responsible homeownership – were introduced by the federal government. Although the changes included measures geared toward curbing foreign real estate speculation and others specific to low loan-to-value mortgages, let’s focus on the change most likely to affect affordability for you, a first-time homebuyer purchasing with less than 20% down: the interest rate stress test.

The affordability of Homeownership has been helped in recent years by low interest rates and the availability of high loan-to-value mortgages backed by mortgage insurance. But what would happen if those interest rates were to jump? Concerned by that scenario, the government introduced tougher interest rate stress-test criteria in fall 2016, with the aim at preparing perspective homebuyers for a future rise in interest rates.

What does that mean for you? More likely than not, less money to work with. Here’s why.

Implications of the stress test

Lenders and mortgage insurers look at two debt service ratios when qualifying you for a mortgage and mortgage insurance.

Gross debt service (GDS)

The carrying costs of your home, such as mortgage payments, taxes, heating, etc., relative to your income.

Total debt service (TDS)

Your home carrying costs (mortgage payments, taxes, heating, etc.) plus your debt payments (credit cards, student loans, car loans, etc.), again relative to your income.To qualify for mortgage insurance, the highest allowable GDS ratio is 39% and the highest allowable TDS ratio is 44%.

While you may qualify for a fantastic five-year fixed mortgage rate from your bank (2.94%, for example), the new rules use the Bank of Canada’s five-year fixed mortgage rate (4.64% in late 2016, for example) to determine whether you can afford your mortgage payments.

This tougher affordability standard acts as a buffer to test whether or not you could still afford your mortgage if interest rates were to rise dramatically.

RESULT: The new rules mean you can afford less house for your income – approximately a 20% to 30% reduction in the mortgage amount you qualify for.

What can you do?

Canada’s new mortgage rules, while the subject of much debate, are here to stay. But the good news is, working within them is possible! You may have to revise your plans or timelines, but first-time homebuyers can still get into the real estate market.

Get yourself on track to buy your first home by laying the groundwork for responsible homeownership: reduce your consumer debt, save for a larger down payment, and boost your overall financial fitness.

Thinking About Buying a Home? Here’s What to Know Before You Start Whether you're buying your very first home or preparing for your next move, the process can feel overwhelming—especially with so many unknowns. But it doesn’t have to be. With the right guidance and preparation, you can approach your home purchase with clarity and confidence. This article will walk you through a high-level overview of what lenders look for and what you’ll need to consider in the early stages of buying a home. Once you’re ready to move forward with a pre-approval, we’ll dive into the details together. 1. Are You Credit-Ready? One of the first things a lender will evaluate is your credit history. Your credit profile helps determine your risk level—and whether you're likely to repay your mortgage as agreed. To be considered “established,” you’ll need: At least two active credit accounts (like credit cards, loans, or lines of credit) Each with a minimum limit of $2,500 Reporting for at least two years Just as important: your repayment history. Make all your payments on time, every time. A missed payment won’t usually impact your credit unless you’re 30 days or more past due—but even one slip can lower your score. 2. Is Your Income Reliable? Lenders are trusting you with hundreds of thousands of dollars, so they want to be confident that your income is stable enough to support regular mortgage payments. Salaried employees in permanent positions generally have the easiest time qualifying. If you’re self-employed, or your income includes commission, overtime, or bonuses, expect to provide at least two years’ worth of income documentation. The more predictable your income, the easier it is to qualify. 3. What’s Your Down Payment Plan? Every mortgage requires some amount of money upfront. In Canada, the minimum down payment is: 5% on the first $500,000 of the purchase price 10% on the portion above $500,000 20% for homes over $1 million You’ll also need to show proof of at least 1.5% of the purchase price for closing costs (think legal fees, appraisals, and taxes). The best source of a down payment is your own savings, supported by a 90-day history in your bank account. But gifted funds from immediate family and proceeds from a property sale are also acceptable. 4. How Much Can You Actually Afford? There’s a big difference between what you feel you can afford and what you can prove you can afford. Lenders base your approval on verifiable documentation—not assumptions. Your approval amount depends on a variety of factors, including: Income and employment history Existing debts Credit score Down payment amount Property taxes and heating costs for the home All of these factors are used to calculate your debt service ratios—a key indicator of whether your mortgage is affordable. Start Early, Plan Smart Even if you’re months (or more) away from buying, the best time to start planning is now. When you work with an independent mortgage professional, you get access to expert advice at no cost to you. We can: Review your credit profile Help you understand how lenders view your income Guide your down payment planning Determine how much you can qualify to borrow Build a roadmap if your finances need some fine-tuning If you're ready to start mapping out your home buying plan or want to know where you stand today, let’s talk. It would be a pleasure to help you get mortgage-ready.

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.

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.
