New Mortgage Rules and CMHC Updates: A Guide for First-Time Buyers

Lee Welbanks • September 17, 2024

In Budget 2024, the Canadian government introduced significant changes to help first-time homebuyers by extending mortgage amortization periods up to 30 years for those purchasing newly built homes. Effective August 1, 2024, this change will help ease monthly mortgage payments, making homeownership more accessible.


Key Eligibility Criteria for First-Time Buyers:

  • First-Time Buyer Status: At least one borrower must qualify as a first-time homebuyer, meaning they have either never owned a home, haven't lived in a home they owned in the past four years, or recently went through a marriage breakdown.
  • Newly Built Homes: The property must be a newly constructed home that has never been occupied.


These extended mortgages will only apply to high-ratio mortgages (loans covering more than 80% of the home’s purchase price) and are limited to owner-occupied properties. All other mortgage insurance eligibility criteria remain unchanged.


CMHC’s New Amortization Rules for Market MLI and MLI Select Programs

The Canada Mortgage and Housing Corporation (CMHC) has also introduced changes. As of June 19, 2024, the maximum amortization period for new construction market projects will increase from 40 years to 50 years. Additionally, the maximum period for re-amortization (for default management) will extend to 55 years for loans under the MLI Select Program.


These changes aim to encourage the construction of more rental housing units while managing housing affordability. CMHC’s modifications also include updates to energy efficiency criteria, lowering the maximum points from 100 to 50 based on energy efficiency, which means developers may need to shift focus toward affordable units to receive maximum benefits.


Changes to "Use of Funds" and Refinancing

CMHC has lifted restrictions on how refinanced funds can be used, reverting to pre-2020 rules. This allows non-approved lenders to offer bridge loans, creating more flexibility in financing options.


Environmental Site Contamination Policies

In response to industry practices, CMHC is reviewing its environmental site contamination policies. For now, projects with known site contamination will be accepted under conditional approval, pending a contamination-free site confirmation.


Why These Changes Matter

For first-time homebuyers, the ability to spread mortgage payments over 30 years is a welcome relief in today’s housing market, particularly for newly built homes. These changes are designed to improve housing affordability and supply, especially for younger Canadians looking to purchase their first home.


Meanwhile, CMHC’s new rules around extended amortizations and energy efficiency adjustments will have a significant impact on developers, especially those focused on building rental properties or using energy-efficient technologies in their projects.

If you're considering buying a home or developing a property, these changes could impact your strategy. To fully understand how these updates may apply to your situation, it's important to consult with a mortgage expert who can offer personalized advice.

If the title of this article caught your attention, chances are your family is growing. Congratulations. If you’re thinking now is the right time to move into a home that better fits your growing family—but you’re unsure how parental leave affects your ability to qualify for a mortgage—you’re in the right place. Here’s the good news. Qualifying for a mortgage while on parental leave is possible when it’s done correctly. When you work with an independent mortgage professional, lenders can often qualify you based on your return-to-work income , as long as you can provide documentation confirming you have guaranteed employment waiting for you. A word of caution If you walk into a bank branch and disclose that you’re currently on parental leave, there’s a chance the bank will only allow you to qualify using your parental leave income. That can significantly reduce your borrowing power. Parental leave income is typically limited to 55% of your previous earnings, up to a weekly maximum. Qualifying on that amount alone can restrict your options and impact the type of home you can purchase. Why lender choice matters One of the biggest advantages of working with an independent mortgage professional is choice . You’re not limited to one lender’s rules or products. Some lenders will allow you to qualify using 100% of your confirmed return-to-work income , which can make a meaningful difference in your approval amount and overall options. What you’ll need to qualify Most lenders will require an employment letter that includes: Employer name (preferably on company letterhead) Your job title Original start date (to confirm probation has been completed) Confirmed return-to-work date Guaranteed salary upon return Lenders want reassurance that your income will resume once parental leave ends. You may also be asked to provide income history from the past couple of years, which is standard for most mortgage applications. One important note Whether or not you actually return to work after parental leave is entirely your decision. From a mortgage perspective, qualification is based on having a confirmed position available to you at the time of approval. If you have questions about qualifying for a mortgage while on parental leave—or anything mortgage-related—please connect anytime. I’d be happy to walk you through your options and help you plan with confidence.

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.
