Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Joel Olson • January 3, 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.

4 Signs You’re Ready for Homeownership

By Joel Olson • October 21, 2025
Buying your first home is a big deal. And while you may feel like you’re ready to take that step, here are 4 things that will prove it out. 1. You have at least 5% available for a downpayment. To buy your first home, you need to come up with at least 5% for a downpayment. From there, you’ll be expected to have roughly 1.5% of the purchase price set aside for closing costs. If you’ve saved your downpayment by accumulating your own funds, it means you have a positive cash flow which is a good thing. However, if you don’t quite have enough saved up on your own, but you have a family member who is willing to give you a gift to assist you, that works too. 2. You have established credit. Building a credit score takes some time. Before any lender considers you for mortgage financing, they want to see that you have an established history of repaying the money you’ve already borrowed. Typically two trade lines, for a period of two years, with a minimum amount of $2000, should work! Now, if you’ve had some credit issues in the past, it doesn’t mean you aren’t ready to be a homeowner. However, it might mean a little more planning is required! A co-signor can be considered here as well. 3. You have the income to make your mortgage payments. And then some. If you’re going to borrow money to buy a house, the lender wants to make sure that you have the ability to pay it back. Plus interest. The ideal situation is to have a permanent full-time position where you’re past probation. Now, if you rely on any inconsistent forms of income, having a two-year history is required. A good rule of thumb is to keep the costs of homeownership to under a third of your gross income, leaving you with two-thirds of your income to pay for your life. 4. You’ve discussed mortgage financing with a professional. Buying your first home can be quite a process. With all the information available online, it’s hard to know where to start. While you might feel ready, there are lots of steps to take; way more than can be outlined in a simple article like this one. So if you think you’re ready to buy your first home, the best place to start is with a preapproval! Let's discuss your financial situation, talk through your downpayment options, look at your credit score, assess your income and liabilities, and ultimately see what kind of mortgage you can qualify for to become a homeowner! Please connect anytime; it would be a pleasure to work with you!

Mortgages Aren’t One-Size-Fits-All

By Joel Olson • October 7, 2025
Why the Cheapest Mortgage Isn’t Always the Smartest Move Some things are fine to buy on the cheap. Generic cereal? Sure. Basic airline seat? No problem. A car with roll-down windows? If it gets you where you're going, great. But when it comes to choosing a mortgage? That’s not the time to cut corners. A “no-frills” mortgage might sound appealing with its rock-bottom interest rate, but what’s stripped away to get you that rate can end up costing you far more in the long run. These mortgages often come with severe limitations—restrictions that could hit your wallet hard if life throws you a curveball. Let’s break it down. A typical no-frills mortgage might offer a slightly lower interest rate—maybe 0.10% to 0.20% less. That could save you a few hundred dollars over a few years. But that small upfront saving comes at the cost of flexibility: Breaking your mortgage early? Expect a massive penalty. Want to make extra payments? Often not allowed—or severely restricted. Need to move and take your mortgage with you? Not likely. Thinking about refinancing? Good luck doing that without a financial hit. Most people don’t plan on breaking their mortgage early—but roughly two-thirds of Canadians do, often due to job changes, separations, relocations, or expanding families. That’s why flexibility matters. So why do lenders even offer no-frills mortgages? Because they know the stats. And they know many borrowers chase the lowest rate without asking what’s behind it. Some banks count on that. Their job is to maximize profits. Ours? To help you make an informed, strategic choice. As independent mortgage professionals, we work for you—not a single lender. That means we can compare multiple products from various financial institutions to find the one that actually suits your goals and protects your long-term financial health. Bottom line: Don’t let a shiny low rate distract you from what really matters. A mortgage should fit your life—not the other way around. Have questions? Want to look at your options? I’d be happy to help. Let’s chat.
