Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Jeff Johnson • 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.

What You Need To Know About Co-Signing A Mortgage

By Jeff Johnson • June 25, 2025
So you’re thinking about co-signing on a mortgage? Great, let’s talk about what that looks like. Although it’s nice to be in a position to help someone qualify for a mortgage, it’s not a decision that you should make lightly. Co-signing a mortgage could have a significant impact on your financial future. Here are some things to consider. You’re fully responsible for the mortgage. Regardless if you’re the principal borrower, co-borrower, or co-signor, if your name is on the mortgage, you are 100% responsible for the debt of the mortgage. Although the term co-signor makes it sound like you’re somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage. When you co-sign for a mortgage, you guarantee that the mortgage payments will be made, even if you aren’t the one making them. So, if the primary applicant cannot make the payments for whatever reason, you’ll be expected to make them on their behalf. If payments aren’t made, and the mortgage goes into default, the lender will take legal action. This could negatively impact your credit score. So it’s an excellent idea to make sure you trust the primary applicant or have a way to monitor that payments are, in fact, being made so that you don’t end up in a bad financial situation. You’re on the mortgage until they can qualify to remove you. Once the initial mortgage term has been completed, you won’t be automatically removed from the mortgage. The primary applicant will have to make a new application in their own name and qualify for the mortgage on their own merit. If they don’t qualify, you’ll be kept on the mortgage for the next term. So before co-signing, it’s a good idea to discuss how long you can expect your name will be on the mortgage. Having a clear and open conversation with the primary applicant and your independent mortgage professional will help outline expectations. Co-signing a mortgage impacts your debt service ratio. When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted in your debt service ratios. This means that if you’re looking to qualify for another mortgage in the future, you’ll have to include the payments of the co-signed mortgage in those calculations, even though you aren’t the one making the payments directly. As this could significantly impact the amount you could borrow in the future, before you co-sign a mortgage, you’ll want to assess your financial future and decide if co-signing makes sense. Co-signing a mortgage means helping someone get ahead. While there are certainly things to consider when agreeing to co-sign on a mortgage application, chances are, by being a co-signor, you'll be helping someone you care for get ahead in life. The key to co-signing well is to outline expectations and over-communicate through the mortgage process. If you have any questions about co-signing on a mortgage or about the mortgage application process in general, please connect anytime. It would be a pleasure to work with you.

First-Time Homebuyer? A New GST Rebate Could Put Thousands Back in Your Pocket

By Jeff Johnson • June 20, 2025
If you’re a first-time homebuyer eyeing a new build or major renovation, there's encouraging news that could make homeownership significantly more affordable. The federal government has proposed a new GST rebate aimed at easing the financial burden for Canadians entering the housing market. While still awaiting parliamentary approval, the proposed legislation offers the potential for thousands in savings —and could be a game-changer for buyers trying to break into today’s high-cost housing landscape. What’s Being Proposed? Under the new legislation, eligible first-time homebuyers would receive: A full GST rebate on homes priced up to $1 million A partial GST rebate on homes between $1 million and $1.5 million This could mean up to $50,000 in tax savings on a qualifying home—a major boost for anyone working hard to save for a down payment or meet mortgage qualification requirements. Why This Matters With interest rates still elevated and home prices holding steady in many regions, affordability remains a challenge. This rebate could offer meaningful relief in several ways: Lower Upfront Costs: Removing GST from the purchase price reduces the total amount of money buyers need to save before closing. Smaller Monthly Payments: A lower purchase price leads to a smaller mortgage, which translates to more manageable monthly payments. Improved Mortgage Qualification: With a reduced purchase amount, buyers may find it easier to meet lender criteria. According to recent estimates, a homebuyer purchasing a $1 million new home could see monthly mortgage payments drop by around $240 —money that could go toward savings, home improvements, or simply everyday expenses. Helping Families Help Each Other This proposal also offers a win for parents who are supporting their children in buying a first home. Whether through gifted down payments or co-signing, a lower purchase price and more affordable monthly costs mean that family support can go further—and set first-time buyers up for long-term success. Is This the Right Time to Buy? If you’re thinking about buying a new or substantially renovated home, this proposed rebate could dramatically improve your financial position. Now is the perfect time to explore your options and make sure your mortgage strategy is aligned with potential policy changes. 📞 Let’s connect for a free mortgage review or pre-approval.
