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.

How to Finance Renovations When Buying a Home in Canada

By Jeff Johnson • August 19, 2026
Can’t Find the Right Home After You’re Pre-Approved? There’s Another Option The best place to start any home purchase is with a mortgage pre-approval. It gives you clarity around your budget and lets you shop with confidence. But what happens when you’ve been pre-approved, you know where you want to live—and nothing suitable fits your price range? This is a common challenge, especially for first-time homebuyers. Before buyer fatigue sets in, it may be worth considering a different approach: buying a home that needs work and financing the renovations as part of your mortgage . What Is a Purchase Plus Improvements Mortgage? A purchase plus improvements program allows you to buy a property and include the cost of approved renovations directly in your mortgage. This can be a great solution if: You can’t find a move-in-ready home within budget You’re open to renovations You want to customize the home from the start It opens up more options and can help you get into a location or property that would otherwise be out of reach. How the Process Works While the idea is straightforward, the process itself is structured and requires planning. Here’s a high-level overview: Renovation quotes are required upfront You’ll need detailed quotes for the work you want completed before final mortgage approval. Renovations must add value The lender must be satisfied that the improvements will increase the property’s value accordingly. Funds are reimbursed, not advanced You pay for the renovations initially. Once the work is completed and verified by an appraiser, the lender reimburses you and adds the cost to your mortgage. With the right guidance, this process is very manageable—but it’s important to understand the steps before committing. Is This Program Right for You? Purchase plus improvements isn’t for everyone. Buying a home is already a big undertaking, and adding renovations can increase stress—especially if timelines, budgets, or contractors become challenging. That said, if you’re financially prepared and like the idea of shaping the home to fit your needs, this program can be an excellent way to get more value and flexibility from your purchase.

Fell Behind on a Payment? Don’t Panic—Here’s What to Do

By Jeff Johnson • August 12, 2026
Missed a Credit Card or Line of Credit Payment? Here’s What to Do If you’ve missed a payment on a credit card or line of credit and you’re worried about how it might affect your credit—or your future mortgage—this is for you. First things first: 👉 If you currently have an overdue balance, log in and make the minimum payment now. Seriously. Do that first. Everything else can wait. If You’re Only a Few Days Late Here’s the good news: Credit bureaus don’t record late payments until they reach 30 days past due. So if you missed a due date by a few days and paid it as soon as you noticed, it typically won’t show up on your credit report as a late payment—as long as you’re under the 30-day mark. That said, it never hurts to double-check. You can call your credit card company, explain what happened, and confirm the account is back in good standing. If you normally pay on time, they may even reverse the interest charged. It doesn’t hurt to ask. If You’re 30, 60, or 90 Days Behind If payments have gone past 30 days, your credit has likely been impacted—but the situation is still fixable. The most important step is to: Bring all accounts current as soon as possible Make at least the minimum payment on every account The faster you catch up, the more you limit the damage. Ignoring missed payments only makes things worse. If Cash Flow Is Tight If you’re struggling to make payments, communication matters. Contact your lender and keep them informed—even if you can’t pay right away. Lenders are far more willing to work with you when you’re transparent. What hurts your credit most is silence . If lenders don’t hear from you after repeated missed payments, they may write the balance off as bad debt and send it to collections. Collections can significantly impact your credit and stay on your report for years. How This Affects Mortgage Qualification Repeated missed payments can make qualifying for a mortgage more difficult—but timing matters. Once you’re back to making regular, on-time payments: Your credit can improve over time The impact of past mistakes becomes less significant If you’re planning to buy a home in the next couple of years, addressing credit issues early gives you far more options later. Final Thoughts Missing a payment doesn’t mean you’re “bad with money,” and it doesn’t mean homeownership is off the table. What matters most is how quickly you respond and how consistent you are going forward .
