Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Welbanks Mortgage Group • 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.

Navigating The Housing Market

By Lee Welbanks • July 16, 2025
If you’ve been thinking about buying a property, whether that be your first home, next home, forever home, or a home to retire into, the current state of the Canadian economy might have you wondering: Is this really the right time to make a move? There is certainly no shortage of doom and gloom in the news out there. The truth is, that’s a tough question to answer in the best of times. It’s nearly impossible to know for sure what’s going to happen next with the housing market in Canada. It could heat up or it could cool down. So here’s some advice. Instead of basing your buying decision entirely on external market factors, like the economy or housing market, consider looking for the answers internally. When you stop looking at the market to determine your timing to buy a home, and instead examine the personal reasons you have for wanting to buy a home, the picture can become much clearer. Here are some questions to consider. Although they are subjective, they will help bring you clarity. Ask yourself: Does buying a property now put me in a better financial position? Do I make enough money now to afford a new home and maintain my lifestyle? Do I feel confident with my current employment status? Have I saved enough money for a down payment? How long do I plan on living in this new home? Is there any scenario where I might have to sell quickly and potentially lose money? Does buying a property now move me closer to my life goals? Do I really want to buy now or am I just feeling a lot of pressure to just buy something? Am I holding back because I'm scared property prices might drop soon? There’s no doubt that buying a home can be stressful, but it doesn’t have to be. Having a plan in place is the best course of action to help you make good decisions and alleviate that stress. If you’d like to have a conversation to discuss your plans, ask some questions, and map out what buying a home looks like for you, we can address many of the unknowns together. The best place to start is to work through a mortgage pre-approval.

Buying a Vacation Home? Here’s What You Need to Know

By Lee Welbanks • July 15, 2025
The idea of owning a vacation home—your own cozy escape from everyday life—is a dream many Canadians share. Whether it’s a lakeside cabin, a ski chalet, or a beachside bungalow, a second property can add lifestyle value, rental income, and long-term wealth. But before you jump into vacation home ownership, it’s important to think through the details—both financial and practical. Start With Your 5- and 10-Year Plan Before you get swept away by the perfect view or your dream destination, take a step back and ask yourself: Will you use it enough to justify the cost? Are there other financial goals that take priority right now? What’s the opportunity cost of tying up your money in a second home? Owning a vacation home can be incredibly rewarding, but it should fit comfortably within your long-term financial goals—not compete with them. Financing a Vacation Property: What to Consider If you don’t plan to pay cash, then financing your vacation home will be your next major step. Mortgage rules for second properties are more complex than those for your primary residence, so here’s what to think about: 1. Do You Have Enough for a Down Payment? Depending on the type of property and how you plan to use it, down payment requirements typically range from 5% to 20%+ . Factors like whether the property is winterized, the purchase price, and its location all come into play. 2. Can You Afford the Additional Debt? Lenders will calculate your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios to assess whether you can take on a second mortgage. GDS: Should not exceed 39% of your income TDS: Should not exceed 44% If you’re not sure how to calculate these, that’s where I can help! 3. Is the Property Mortgage-Eligible? Remote or non-winterized properties, or those located outside of Canada, may not qualify for traditional mortgage financing. In these cases, we may need to look at creative lending solutions . 4. Owner-Occupied or Investment Property? Whether you’ll live in the home occasionally, rent it out, or use it strictly as an investment affects what type of financing you’ll need and what your tax implications might be. Location, Location… Logistics Choosing the right vacation property is more than just finding a beautiful setting. Consider: Current and future development in the area Available municipal services (sewer, water, road maintenance) Transportation access – how easy is it to get to your vacation home in all seasons? Resale value and long-term potential Seasonal access or weather challenges What Happens When You’re Not There? Unless you plan to live there full-time, you'll need to consider: Will you rent it out for extra income? Will you hire a property manager or rely on family/friends? What’s required to maintain valid home insurance while it’s vacant? Planning ahead will protect your investment and give you peace of mind while you’re away. Not Sure Where to Start?
