Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Wyatt Tunnicliffe • January 2, 2025

As housing affordability challenges persist across Canada, innovative solutions are reshaping the way homeowners can contribute to housing supply. Starting January 15, 2025, new mortgage insurance rule changes will allow Canadian homeowners to access insured refinancing options to create secondary suites, such as basement apartments or laneway homes.


This move, announced in Budget 2024 and detailed by the Department of Finance Canada, is part of a broader strategy to increase housing density and improve affordability while offering homeowners the chance to generate additional income.


Why These Changes Matter

Historically, converting extra space into rental units has been both costly and mired in municipal red tape. Recent zoning reforms across Canada’s major cities, driven by Housing Accelerator Fund agreements, are reducing these barriers. The creation of secondary suites not only expands housing supply but also provides financial benefits to homeowners, such as offering seniors additional income to support aging in place.


Key Parameters for the New Rules

The new mortgage insurance program is designed to enable homeowners to build legal, self-contained secondary suites that comply with municipal requirements.


Here are the essential details:


Eligibility Requirements

  • Homeowners must already own the property.
  • The homeowner or a close relative must occupy one of the existing units.
  • Additional units must not be used as short-term rentals.


Project Specifications

  • New units must be fully self-contained with separate entrances (e.g., basement suites, laneway homes).
  • Up to four total dwelling units are allowed, including existing units.


Financial Parameters

  • The “as improved” property value must be less than $2 million.
  • Homeowners can refinance up to 90% of the property’s value, including the enhanced value from secondary suites.
  • The maximum amortization period is 30 years.
  • Additional financing must not exceed the project’s costs.


When Do These Rules Take Effect?

Starting January 15, 2025, lenders can submit applications for mortgage insurance under these updated parameters. This applies to all eligible properties across Canada, provided the new units align with municipal zoning requirements.


What This Means for Homeowners

For homeowners with underutilized space, such as basements or detached garages, this new program offers an opportunity to increase property value and create a source of long-term income. By building legal secondary suites, homeowners can contribute to Canada’s rental housing market while gaining financial security.


A Step Toward Housing Solutions

As housing supply remains a pressing issue, these mortgage insurance changes reflect a commitment to practical, homeowner-driven solutions. Whether you’re a senior looking to age in place or a family seeking to maximize your property’s potential, these changes represent an exciting opportunity to invest in your home and your community.


Stay informed and explore your options with your lender to determine if this program is right for you. The path to unlocking your property’s potential begins in 2025.

Need to Free Up Some Cash? Your Home Equity Could Help If you've owned your home for a while, chances are it’s gone up in value. That increase—paired with what you’ve already paid down—is called home equity, and it’s one of the biggest financial advantages of owning property. Still, many Canadians don’t realize they can tap into that equity to improve their financial flexibility, fund major expenses, or support life goals—all without selling their home. Let’s break down what home equity is and how you might be able to use it to your advantage. First, What Is Home Equity? Home equity is the difference between what your home is worth and what you still owe on it. Example: If your home is valued at $700,000 and you owe $200,000 on your mortgage, you have $500,000 in equity . That’s real financial power—and depending on your situation, there are a few smart ways to access it. Option 1: Refinance Your Mortgage A traditional mortgage refinance is one of the most common ways to tap into your home’s equity. If you qualify, you can borrow up to 80% of your home’s appraised value , minus what you still owe. Example: Your home is worth $600,000 You owe $350,000 You can refinance up to $480,000 (80% of $600K) That gives you access to $130,000 in equity You’ll pay off your existing mortgage and take the difference as a lump sum, which you can use however you choose—renovations, investments, debt consolidation, or even a well-earned vacation. Even if your mortgage is fully paid off, you can still refinance and borrow against your home’s value. Option 2: Consider a Reverse Mortgage (Ages 55+) If you're 55 or older, a reverse mortgage could be a flexible way to access tax-free cash from your home—without needing to make monthly payments. You keep full ownership of your home, and the loan only becomes repayable when you sell, move out, or pass away. While you won’t be able to borrow as much as a conventional refinance (the exact amount depends on your age and property value), this option offers freedom and peace of mind—especially for retirees who are equity-rich but cash-flow tight. Reverse mortgage rates are typically a bit higher than traditional mortgages, but you won’t need to pass income or credit checks to qualify. Option 3: Open a Home Equity Line of Credit (HELOC) Think of a HELOC as a reusable credit line backed by your home. You get approved for a set amount, and only pay interest on what you actually use. Need $10,000 for a new roof? Use the line. Don’t need anything for six months? No payments required. HELOCs offer flexibility and low interest rates compared to personal loans or credit cards. But they can be harder to qualify for and typically require strong credit, stable income, and a solid debt ratio. Option 4: Get a Second Mortgage Let’s say you’re mid-term on your current mortgage and breaking it would mean hefty penalties. A second mortgage could be a temporary solution. It allows you to borrow a lump sum against your home’s equity, without touching your existing mortgage. Second mortgages usually come with higher interest rates and shorter terms, so they’re best suited for short-term needs like bridging a gap, paying off urgent debt, or funding a one-time project. So, What’s Right for You? There’s no one-size-fits-all solution. The right option depends on your financial goals, your current mortgage, your credit, and how much equity you have available. We’re here to walk you through your choices and help you find a strategy that works best for your situation. Ready to explore your options? Let’s talk about how your home’s equity could be working harder for you. No pressure, no obligation—just solid advice.
