Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Shanna Davis • 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.

Standard or Collateral Charge Mortgage. What’s best for you?

By Shanna Davis • October 30, 2025

When arranging mortgage financing, your mortgage lender will register your mortgage in one of two ways. Either with a standard charge mortgage or a collateral charge mortgage. Let’s look at the differences between the two. Standard charge mortgage This is your good old-fashioned mortgage. A standard charge mortgage is the mortgage you most likely think about when you consider mortgage financing. Here, the amount you borrow from the lender is the amount that is registered against the title to protect the lender if you default on your mortgage. When your mortgage term is up, you can either renew your existing mortgage or, if it makes more financial sense, you can switch your mortgage to another lender. As long as you aren’t changing any of the fine print, the new lender will usually cover the cost of the switch. A standard charge mortgage has set terms and is non-advanceable. This means that if you need to borrow more money, you'll need to reapply and requalify for a new mortgage. So there will be costs associated with breaking your existing mortgage and costs to register a new one. Collateral charge mortgage A collateral charge mortgage is a mortgage that can have multiple parts, usually with a re-advanceable component. It can include many different financing options like a personal loan or line of credit. Your mortgage is registered against the title in a way that should you need to borrow more money down the line; you can do so fairly easily. A home equity line of credit is a good example of a collateral charge mortgage. Unlike a standard charge mortgage, here, your lender will register a higher amount than what you actually borrow. This could be for the property's full value, or some lenders will go up to 125% of your property's value. In the future, if the value of your property appreciates, with a collateral charge mortgage, you don't have to rewrite your existing mortgage to borrow more money (assuming you qualify). This will save you from any costs associated with breaking your existing mortgage and registering a new one. However, if you’re looking to switch your mortgage to another lender at the end of your term, you might be forced to discharge your mortgage and incur legal fees. Also, by registering your mortgage with a collateral charge, you potentially limit your ability to secure a second mortgage. So what’s a better option for you? Well, there are benefits and drawbacks to both. Finding the best option for you really depends on your financial situation and what you believe gives you the most flexibility. This is probably a question better handled in a conversation rather than in an article. With that said, undoubtedly, the best option is to work with an independent mortgage professional. It’s our job to understand the intricacies of mortgage financing, listen to and assess your needs, and recommend the best mortgage to meet your needs. As we work with many lenders, we can provide you with options. Don’t get stuck dealing with a single institution that may only offer you a collateral charge mortgage when what you need is a standard charge mortgage. So if you’d like to have a conversation about mortgage financing, please get in touch. It would be a pleasure to work with you and answer any questions you might have.

Everything You Need to Know About Second Mortgages

By Shanna Davis • October 16, 2025

What Is a Second Mortgage, Really? (It’s Not What Most People Think) If you’ve heard the term “second mortgage” and assumed it refers to the next mortgage you take out after your first one ends, you’re not alone. It’s a common misconception—but the reality is a bit different. A second mortgage isn’t about the order of mortgages over time. It’s actually about the number of loans secured against a single property —at the same time. So, What Exactly Is a Second Mortgage? When you first buy a home, your mortgage is registered on the property in first position . This simply means your lender has the primary legal claim to your property if you ever sell it or default. A second mortgage is another loan that’s added on top of your existing mortgage. It’s registered in second position , meaning the lender only gets paid out after the first mortgage is settled. If you sell your home, any proceeds go toward paying off the first mortgage first, then the second one, and any remaining equity is yours. It’s important to note: You still keep your original mortgage and keep making payments on it —the second mortgage is an entirely separate agreement layered on top. Why Would Anyone Take Out a Second Mortgage? There are a few good reasons homeowners choose this route: You want to tap into your home equity without refinancing your existing mortgage. Your current mortgage has great terms (like a low interest rate), and breaking it would trigger hefty penalties. You need access to funds quickly , and a second mortgage is faster and more flexible than refinancing. One common use? Debt consolidation . If you’re juggling high-interest credit card or personal loan debt, a second mortgage can help reduce your overall interest costs and improve monthly cash flow. Is a Second Mortgage Right for You? A second mortgage can be a smart solution in the right situation—but it’s not always the best move. It depends on your current mortgage terms, your equity, and your financial goals. If you’re curious about how a second mortgage could work for your situation—or if you’re considering your options to improve cash flow or access equity—let’s talk. I’d be happy to walk you through it and help you explore the right path forward. Reach out anytime—we’ll figure it out together.
