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.

Everything You Should Know Before Buying a Home

By Marci Deane • March 11, 2026
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.
